CT evaluation of sigmoid plate dehiscence causing pulsatile tinnitus.

To evaluate the characteristics of sigmoid plate dehiscence (SPD) causing pulsatile tinnitus (PT) on CT arteriography and venography (CTA + V). Thirty PT patients treated successfully with SPD reconstruction were enrolled. Sixty asymptomatic patients were matched. The location, extent, number of SPD cases and concomitant signs, including venous outflow dominance, transverse sinus stenosis, high jugular bulb, temporal bone pneumatization, height of pituitary gland and pituitary fossa, abnormal mastoid emissary vein, were detected and compared using CTA + V. More than one SPD was found on the symptomatic side in 13/30 PT patients (43.3 %). The upper segment of the sigmoid plate was involved in 29/44 SPDs in the vertical direction (65.9 %); the lateral wall was involved in 38/44 SPDs in the horizontal direction (86.4 %). Singular SPD was detected in 3/60 asymptomatic patients (1.67 ± 0.35 mm(2)), less so in PT patients (7.97 ± 5.17 mm(2)). Compared with the control group, ipsilateral venous outflow dominance, high jugular bulb and bilateral transverse sinus stenosis were more common in the PT group, together with deeper pituitary fossa and flatter pituitary glands. SPD causing PT has characteristic CT findings. It may be generated by vascular or intracranial pressure abnormalities and act as a common key to triggering PT's perception. Pulsatile tinnitus (PT) caused by sigmoid plate dehiscence (SPD) may be cured. SPD causing PT has some characteristic findings on CT. SPD may be a common key to triggering PT's perception. Thin-slice high resolution CT venography is recommended for SPD assessment. The relationship between intracranial pressure and SPD causing PT should be studied.

Treatment Outcomes From Pentoxifylline in Sclerosing Mesenteritis

Introduction: Sclerosing mesenteritis (SM) is a rare, chronic fibrosing and inflammatory disorder affecting the small bowel mesentery. Pentoxifylline has anti-inflammatory properties that could potentially benefit this disease. There is limited data on the efficacy of pentoxifylline for other fibroinflammatory disorders. We performed a retrospective chart review of patients with SM who were treated with pentoxifylline. Methods: ICD-9 codes were used to identify patients with SM, and free text search for pentoxifylline was used. Clinical data was abstracted from the electronic medical record and patients were called for followup. Data analysis was performed using JMP version 9.0.1. Results: Eleven patients were identified with median age of 64 years (range 39-75), and 36% were female. At presentation, abdominal pain was present in 10/11 (91%), abdominal distention or bloating was present in 8/11 (73%), and 7/11 (64%) had nausea or vomiting. Eighty-two percent (9/11) had a biopsy-proven SM, while the other 2 patients had characteristic CT findings without biopsy. Imaging findings at diagnosis included mesenteric mass in 6/11 (55%), mesenteritis without mass in 5/11 (45%), and lymphadenopathy in 4/11 (36%). Eight patients were prescribed tamoxifen prior to pentoxifylline; all 8 discontinued use (2 due to thromboembolism, 1 due to intolerance, 5 due to no response). The most common pentoxifylline dose was 400 mg 3 times a day (50% of patients), median duration was 4 months (range 1-30). Long-term follow-up data was available in 7 patients. Five patients were on prednisone while taking pentoxifylline. Two out of 7 patients (28.57%) experienced complete clinical improvement, 2/7 (28.57%) partial improvement, 3/7 (42.86%) no response. One patient had complete resolution of inflammatory changes on abdominal MRI. Two patients experienced nausea secondary to pentoxifylline, 1 of them requiring discontinuation. One patient died from refractory intestinal obstruction. Follicular large-cell lymphoma was diagnosed in 1 patient at follow-up. Conclusion: Pentoxifylline appears to be a reasonable treatment option for patients with SM that did not respond to tamoxifen. It appears to be well-tolerated, with only 1 patient stopping due to side effects. However, larger studies are necessary to better estimate the benefits and side effect profile of pentoxifylline in SM.

Dentigerous cysts with calcification mimicking odontogenic tumors: differential diagnosis by CT

This study aimed at clarifying whether we can differentiate dentigerous cysts with calcified substances from other odontogenic tumors that include calcification and the crown of an unerupted tooth by CT findings. We retrospectively selected histopathologically confirmed cases that included calcified substances and the crown of an unerupted tooth inside. There were 22 cases with eight pathological categories. Besides seven odontogenic tumors, we included dentigerous cysts, which were usually recognized without calcification within the lesions. We divided the cases into two groups: 14 cases of odontogenic tumors and 8 cases of dentigerous cysts. Cases were analyzed for various CT findings such as continuity with the alveolar crest, bone sclerosis around the lesion, and sizes and shapes of high CT value substances, as well as demographic factors. Comparisons between the groups for each analytical factor were performed. Dentigerous cysts with dystrophic calcification showed unique CT findings such as bone sclerosis around the lesion, continuity with the alveolar crest, and small scattered calcified substances near the crown of an unerupted tooth, compared with typical dentigerous cysts and other odontogenic tumors. On the other hand, odontogenic tumors showed various patterns in the location and distribution of high CT value substances, and we could only differentiate odontoma using its very high CT values. Although the patterns of calcification were not the main characteristic findings, it may be possible to differentiate dentigerous cysts with dystrophic calcification from odontogenic tumors by their other characteristic CT findings, and unnecessary extensive surgery can also be avoided.

Congenital distal tibio-fibular synostosis: A case report.

Congenital distal tibio-fibular synostosis is a very rare anomaly. The cases of congenital tibio- fibular synostosis reported in the literature so far have been confined to the proximal tibio-fibular joint. We present a case of tibio-fibular synostosis that involves the distal part of the tibia and fibula based on characteristic X-ray and CT findings. We have also attempted to classify the distal tibio-fibular synostosis. At the end we have discussed different modes of presentation of the condition and various management strategies. Key-words : tibio-fibular synostosis, distal, congenital

Thrombophlebitis of the internal jugular vein (Lemierre syndrome): clinical and CT findings

Thrombophlebitis of the internal jugular vein (IJV) secondary to neck infection (so-called Lemierre syndrome) is a rare disease. To evaluate the clinical and CT findings in patients with thrombophlebitis of the IJV. The clinical and contrast-enhanced neck CT findings were retrospective analyzed in 10 patients (eight men, two women; mean age, 62.9 ± 8.3 years) with thrombophlebitis of the IJV. Five patients (50%) had complications, including pneumonia (n = 3), neck abscess (n = 1), and thrombophlebitis of cerebral venous sinus (n = 1). All patients, except two who were lost to follow-up, had improved after antibiotics and anticoagulation therapy. Nine (90%) patients had underlying infectious processes in the neck. Contrast-enhanced neck CT of 12 IJVs (five right, three left, and two bilateral) affected by thrombophlebitis demonstrated > 5 cm in length (n = 8, 67%), ovoid shape (n = 7, 58%), complete occlusion of the lumen (n = 10, 83%), circumferential (n = 11, 92%), smooth (n = 8, 67%), and thick (≥4 mm) (n = 8, 67%) rim enhancement, and adjacent soft tissue swelling (n = 11, 92%). Contrast-enhanced CT is useful in the diagnosis of thrombophlebitis of the IJV; characteristic CT findings of this unusual entity may be the main clue to the correct diagnosis.

Utility of ECG-gated MDCT to differentiate patients with ARVC/D from patients with ventricular tachyarrhythmias

BackgroundThe accuracy of electrocardiogram-gated CT for diagnosing arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is uncertain. ObjectiveWe propose a comprehensive system for scoring characteristic CT findings to diagnose ARVC/D and discuss its utility. MethodsSeventy-seven patients (mean age, 43.1 years; 48 male) diagnosed with ARVC/D or with suspected ARVC/D on the basis of ventricular tachyarrhythmias underwent CT with and without contrast enhancement. We retrospectively graded characteristic CT findings (fatty tissue, bulging appearance, and dilatation of the right ventricle) as minor (1 point) or major (2 points) and then validated our scoring system’s utility for diagnosing ARVC/D with the use of the modified 2010 Task Force criteria as the reference standard. ResultsWe diagnosed 27 of 77 patients with ARVC/D (23 definite, 4 borderline), observing each CT finding more often in patients with ARVC/D than in patients without ARVC/D: fatty tissue, 74.1% versus 12.0%; bulging appearance, 74.1% versus 34.0%; and RV dilatation, 92.6% versus 44.0%. However, observation of each finding in both groups could cause false positive diagnosis. Recursive partitioning analysis showed the superiority of our CT scoring system over methods that used each CT finding and CT findings without fatty tissue for distinguishing ARVC/D and non-ARVC/D. For overall (definite and borderline) and definite ARVC/D diagnosis, sensitivities were 77.8% and 87.0%, specificities were 96.0% and 94.4%, positive predictive values were 91.3% and 87.0%, negative predictive values were 88.9% and 94.4%, and accuracies were 89.6% and 92.2%, respectively. ConclusionsOur CT scoring system showed excellent diagnostic ability and might aid differentiation of ARVC/D from ventricular tachyarrhythmias.

Sclerosing Angiomatoid Nodular Transformation of the Spleen: CT and MRI Features With Pathologic Correlation

The objective of this study was to describe the CT and MRI features of sclerosing angiomatoid nodular transformation of the spleen with pathologic correlation. Nine patients with surgically resected and pathologically confirmed sclerosing angiomatoid nodular transformation were included in the study. Clinical history was reviewed to determine patient demographics and symptoms at presentation. Gross pathologic, histologic, and immunohistochemical findings were recorded. CT (n = 9) and MRI (n = 4) examinations were evaluated for lesion shape and margins, intrinsic characteristics, and enhancement pattern. Patients included were six women and three men, with a mean age of 41.2 years. Pathologic features of sclerosing angiomatoid nodular transformation included multiple angiomatous nodules in a radiating pattern with a central stellate fibrous scar and evidence of hemosiderin deposition. On imaging, the lesions were solitary and round, 78% having a lobulated margin. They were heterogeneously hypoenhancing during the arterial and portal venous phases of contrast-enhanced CT or MRI, with peripheral enhancing radiating lines in 88% of lesions. They showed progressive enhancement and were isoenhancing or hyperenhancing in the delayed phase. A hypoenhancing central scar was shown on imaging in 22% of lesions. All lesions were hypointense on T2-weighted images. Sclerosing angiomatoid nodular transformation shows characteristic CT and MRI findings reflecting the underlying pathology. Typical features are a solitary, round, lobulated mass with early peripheral enhancing radiating lines and progressive enhancement of the angiomatous nodules; delayed enhancement of the fibrous tissue; and hypo-intense T2 signal intensity from hemosiderin deposition.

細菌性髄膜炎の経過中に“Mount Fuji sign”画像所見を呈した緊張性気脳症の1例

A 39-year-old man was suffered from bacterial meningitis spread from sphenoid sinusitis. During the first several days of the hospitalization, his clinical and laboratory findings were improved by the antibiotics. But he developed impaired consciousness and paraparesis on the sixth hospital day. A CT scan of the brain revealed pneumocephalus with compression of frontal lobes and the widening of the interhemispheric space between the tips of the frontal lobes, which was known as "Mount Fuji sign". Tension pneumocephalus was diagnosed on the basis of the clinical symptoms and the characteristic CT findings. As the bacterial meningitis itself was improving, the surgical treatment was not performed, but the antibiotics therapy continued. He gradually recovered and discharged without any other complications. The mechanism of tension pneumocephalus could not be disclosed. However, it was speculated that tension pneumocephalus was formed due to combined conditions of following factors; the fistula formation between sphenoid sinus and subdural space, the reduced CSF pressure on lumbar puncture, and a ball-valve mechanism though the fistula. We would emphasize that "Mount Fuji sign"on CT or MRI was the important finding to diagnose tension pneumocephalus.

Spreading pattern and CT findings of very early-stage peripheral small-cell lung cancer

Chest CT frequently reveals small pulmonary lesions. If there is no associated hilar or mediastinal lymphadenopathy, small-cell lung cancer (SCLC) is considered to be very early-stage. Few studies, however, have described the characteristic CT findings of very early-stage SCLC. Clarifying these findings would reduce diagnostic delay. The purpose of this study was to determine the characteristic CT findings of very earlystage SCLC. Computed tomography images obtained from 547 consecutive patients with lung cancer between 2003 and 2012 at Tokyo Dental College Ichikawa General Hospital were reviewed retrospectively. One hundred of these patients had SCLC and 447 had non-SCLC (NSCLC). These CT images, along with any that had also been obtained prior to the one on which the final diagnosis was based, were reviewed. In 5 of the cases reviewed, specific findings and a characteristic spreading pattern were identified on CT images that might have allowed a diagnosis of SCLC to have been made sooner. The findings included a sub-pleural, small nodule accompanied by daughter nodules spreading longitudinally along the bronchovascular bundle, no air bronchogram or cavitation, and background emphysematous change. These were not identified on CT images of very earlystage NCSLC, however (n = 22). Awareness of the relevance of these findings would help physicians and radiologists arrive at a differential diagnosis of small pulmonary nodules.

Small Renal Oncocytomas: Is Segmental Enhancement Inversion a Characteristic Finding at Biphasic MDCT?

The purpose of this study was to retrospectively determine whether segmental enhancement inversion was a common and characteristic finding in small (≤ 4 cm) renal oncocytomas on biphasic contrast-enhanced CT. This retrospective case-control study included 16 patients with 16 renal oncocytomas and 15 control patients with 15 renal cell carcinomas (RCCs), matched for age and sex, who underwent biphasic contrast-enhanced MDCT at our institution. Three reviewers independently analyzed each tumor for enhancement patterns on MDCT, including the presence or absence of segmental enhancement inversion, homogeneity, and phase of peak enhancement. The mean and median sizes of the oncocytomas were 2.5 and 2.4 cm, respectively (range, 1.1-3.9 cm), and the mean and median sizes of the RCCs were both 2.6 cm (range, 1.4-3.9 cm). There was no significant difference in the size of the renal masses between the two groups (p = 0.50). For two reviewers, segmental enhancement inversion was not present in any of the renal masses; for one reviewer, segmental enhancement inversion was present in one oncocytoma (6%) and one RCC (7%). For all reviewers, there was no feature or enhancement pattern that was statistically significantly associated with renal oncocytoma or RCC (p < 0.05). Segmental enhancement inversion was not a common or characteristic CT finding for renal oncocytoma and was not helpful in differentiating small renal oncocytomas from RCC.

CT and MR Imaging Findings of Sinonasal Schwannoma: A Review of 12 Cases

Schwannomas are benign tumors that are rarely found in the sinonasal cavity, and the purpose of this study was to characterize the CT and MR imaging findings of 12 patients with surgically proved sinonasal schwannomas. Assessed features include location, margin, shape, size, internal architecture, pattern and degree of enhancement, and associated bony wall changes. The characteristic CT and MR imaging findings of sinonasal schwannoma include a well-defined soft-tissue mass, most frequently occurring in the nasal cavity and ethmoid sinus with pressure remodeling of the adjacent bony wall. The tumors were isoattenuating on CT and predominantly isointense on both T1- and T2-weighted MR images, compared with the brain stem. Mild contrast enhancement on CT and strong enhancement on MR images were also demonstrated in most of the tumors, and cystic or hemorrhagic changes were noted in 2 cases.

Characteristic CT findings and pathologic basis of ground glass opacity caused by pulmonary alveolar proteinosis

To explore characteristic CT findings and pathologic basis of ground glass opacity caused by pulmonary alveolar proteinosis (PAP). Retrospective analysis of CT and pathological findings of 24 patients with PAP who were pathologically diagnosed from June 2006 to August 2011. Findings with CT: the lesions of the 24 patients mainly presented ground glass opacities. Local consolidations were seen in 8 patients. In 23 patients part of ground glass opacities bordered strip-shaped opacities with smooth edges, and there was a clear boundary between them and the bordering normal lung tissues, presenting a geographic appearance. Lesions in the 5 cases were mixed with alveoli or lobule aerocele, which made ground glass opacities present curved edges. Crazy paving pattern was detected in the 24 patients. Microscopically, the alveoli were seen to be filled with floccules proteinaceous material in various quantities in the 24 patients; hemangiectasis and congestion were seen in 17 patients, and enlarged alveolar cavities were seen in 5 patients. PAP usually causes ground glass opacities with clear edges, and different from ground glass opacities with obscure edges caused by other pulmonary diseases. They are relatively specific to the imagining diagnosis to PAP.

Infected tracheal diverticulum mimicking an aggressive mediastinal lesion on FDG PET/CT: an interesting case with review of the literature

The differential diagnosis for intense hypermetabolic mediastinal lesions on positron emission tomography (PET) could benefit from the combined morphological and metabolic information present in a fluorodeoxyglucose (FDG) PET/CT study. We report a case of an infected tracheal diverticulum mimicking an FDG-avid malignancy in a patient with a history of chronic lymphoproliferative disease. We review the literature for a systematic approach in the differential diagnosis of cystic mediastinal lesions. The embryological development of the normal tracheobronchial tree is reviewed, followed by a presentation of various congenital and acquired mediastinal lesions. The characteristic CT findings are described for each lesion and the avidity for FDG on PET is mentioned when references are available. This case emphasises that complicated benign processes should be considered in the differential diagnosis of an FDG-avid mediastinal lesion, even in subgroups of patients with significant risk factors for malignancy.

Non-inflammatory aortoiliac aneurysm with ureteral obstruction and consequent hydronephrosis: Case report

The natural course of abdominal aneurysms is progressive expansion, rupture, embolisation, thrombosis and compression of the visceral organs. The majority of papers report that inflammatory aortic and iliac aneurysms are associated with perianeurysmal and retroperitoneal fibrosis that ultimately results in the structural compromise of the urinary tract. Ureteral obstruction occurs in 20% to 71% of cases and approximately one half of these patients will present with obstructive uropathy. Most patients with inflammatory aneurysm are symptomatic, with elevated serum inflammatory markers, and characteristic multislice CT findings including a thickened aortic wall and a mass of periaortic inflammatory tissue. A 70-year-old man was admitted at the Vascular Surgery Clinic "Dedinje", Belgrade, because of ultrasonically verified asymptomatic aortoiliac aneurysm. Multisclice CT findings showed left urethral dilatation and hydronephrosis secondary to extrinsic ureteral obstruction due to aortoiliac aneurysm. CT findings, laboratory tests and finally, histopathologic examination showed atherosclerotic aneurysm without inflammation and retroperitoneal fibrosis. The patient was successfully treated with surgical resection of the aneurysm and aortobiliac reconstruction with "Y" prosthesis. We present a rare case of ureteral obstruction secondary to atherosclerotic aneurysm which, to our knowledge, has not been previously described in the domestic literature. A successful operative repair was performed. Postoperative course was uneventful and the patient was discharged on the seventh day after the surgery with normal vascular status and renal function.

Kimura Disease: CT and MR Imaging Findings

KD is a rare chronic inflammatory disorder of unknown etiology. The purpose of this study was to evaluate the CT and MR imaging findings of KD in the head and neck. We retrospectively reviewed the CT (n = 21) and MR (n = 9) images obtained in 28 patients (24 males and 4 females; mean age, 32 years; age range, 10-62 years) with histologically proved KD in the head and neck. In these 28 patients, CT and MR images demonstrated a total of 52 non-nodal lesions, 1-8 cm in greatest diameter, in the head and neck. The lesions were unilateral in 11 patients and bilateral in 17 patients. Eleven patients had a solitary lesion, and 17 patients had 2-4 lesions. The parotid and/or periparotid area was the most frequent location, with 36 lesions in 23 patients. The margin of the lesions was well-defined in 1 and ill-defined in 51 cases. Compared with the adjacent muscle, the MR signal intensity of all lesions was iso- to slightly hyperintense on T1-weighted images and hyperintense on T2-weighted images. Most of the lesions demonstrated mild or moderate enhancement on postcontrast CT scans and moderate or marked enhancement on postcontrast MR images. MR images also showed tubular signal-intensity voids in 7 of 13 lesions. Associated lymphadenopathy was demonstrated in 23 patients, usually bilaterally. Multiple ill-defined enhancing masses within and around the parotid gland with associated regional lymphadenopathy are characteristic CT and MR imaging findings of KD in the head and neck.

Prevertebral Calcific Tendinitis

Objective: 1) Recognize that prevertebral calcific tendinitis of the longus colli is a rare inflammatory noninfectious cause of retropharyngeal fluid. 2) Understand that appropriate treatment of this condition is with anti-inflammatory medications rather than antibiotics and/or surgical drainage. Method: We report a rare case of retropharyngeal effusion caused by prevertebral calcific tendinitis of the longus colli muscle. The patient was evaluated and treated in the emergency department of an urban university hospital and was seen one week later in the otolaryngology clinic. Results: Prevertebral calcific tendinitis of the longus colli is a rare entity that may cause an effusion that can be misdiagnosed as a retropharyngeal abscess. Our patient presented with a 1 day history of worsening neck pain and stiffness, and dysphagia. Absence of fever and a normal white cell count were noted. CT scan revealed a nonrim-enhancing, nonbulging retropharyngeal fluid collection and calcification of the longus colli tendons near the C2 vertebrae. One dose of intravenous dexamethasone was administered, and the patient’s neck stiffness markedly improved. At 1-week follow-up, his symptoms had completely resolved on a steroid taper. Conclusion: Prevertebral calcific tendinitis of the longus colli may cause a retropharyngeal effusion mimicking abscess. Prompt diagnosis can be made by recognizing the characteristic CT findings in the context of absent clinical evidence for infection. Anti-inflammatory medications are the treatment of choice.

Tuberculosis of the Male Genitourinary Tract

Background Information In the past decade, there has been a significant rise in the prevalence of tuberculosis as well as an increase in the extrapulmonary manifestations worldwide. Genitourinary tuberculosis is the most common manifestation of extrapulmonary tuberculosis. Diagnosis is often difficult and delayed because tuberculosis has a variety of clinical and radiological presentations, and it can mimic numerous other disease entities. A high level of suspicion is required and positive results on culture or histologic examination of biopsy or surgical specimens is still required in many patients for definite diagnosis. Educational Goals • To review the ultrasonographic features of tuberculosis affecting the kidney, adrenal gland, and male genital tracts. • To know the routes of Tuberculous spread. Imaging Findings Tuberculous infection occur all genitourinary organs, kidney, adrenal gland, ureter, urinary bladder, prostate, epididymis and testes. We reviewed pathophysiology of Tuberculous infection affecting male genitourinary tracts. We also reviewed the characteristic ultrasonographic and CT findings of Tuberculous infection. We compared other differential diagnostic diseases (inflammatory bowel diseases, peritoneal diseases) to these ultrasonographic and CT manifestations. Conclusion Tuberculous infection can mimic numerous other disease entities. Although a positive culture of histologic analysis of biopsy specimens is still required in many patients to yield the definite diagnosis, recognition and understanding of the spectrum of imaging features of extrapulmonary tuberculosis can aid in diagnosis.

Patterns of Fat Stranding

I n the setting of abdominal pain, whether acute or chronic, CT is helpful, and frequently essential, in discovering the underlying cause. Fat stranding is a common finding on CT of the abdomen and, when present, it directs the radiologist’s attention to the site of pathology. However, there is a wide differential for this pattern. The following logical approach to abdominal fat stranding on CT can lead to the formulation of a succinct and accurate differential diagnosis: 1. What is the location of the fat stranding? 2. What other structures are involved in the process? 3. Are there other characteristic CT findings of the diagnostic possibilities that suggest the most likely cause? Fat stranding refers to an abnormal increased attenuation in fat, (in the mesentery, omentum, retroperitoneum, or subcutaneous fat). The underlying pathophysiologic process is increased edema and engorgement of lymphatics. Abdominal fat stranding can produce various appearances. Whereas mild inflammation may cause a subtle hazy increased attenuation of the fat (ground-glass like), increasing severity of the inflammation can produce a reticular pattern, with more well-defined linear areas of increased attenuation. A reticulonodular appearance can also be observed frequently in association with neoplastic disease.
