Unusual Sonographic Findings Research Articles

Multiple foreign body granulomas after mastectomy with intraoperative application of tissue adhesive vs. surgical drainage - sonographic finding.

The use of tissue adhesive instead of a drain following mastectomy was a point of interest for many breast surgeons. Postoperative formation of multiple unusual sonographic lesions was observed in patients that underwent mastectomy with TissuGlu. The aim of this study was to describe the sonographic features of these lesions and, when possible, to examine them histologically. This study includes 98 patients, 49 underwent mastectomy with the application of TissuGlu and 49 with drain insertion. Unusual postoperative sonographic findings were thoroughly described. A histological examination was carried out according to the guideline recommendations. Unusual sonographic findings were detected in 87.8% of patients in the TissuGlu group and in only 4% of the patients in the drain group. These lesions were detectable between 6 and 59 months postoperatively. 47 breasts of the TissuGlu group were classified as category 3, while only 2 breasts as category 4. Lesions were on average 7.5 mm in diameter, echogenic or isoechoic with posterior shadowing, an irregular and ill circumscribed marginal contour, and a horizontal axis. All histologically examined lesions (n=29) were benign. Granulomatous tissue was histologically proven in 63% of those lesions (n=17), while residual adhesive material could be detected in 18.5% of lesions (n=5). The use of TissuGlu adhesive after mastectomy may cause the formation of unusual palpable granulomas, with or without residual adhesive materials. Sonographic description of lesions will help physicians to differentiate between granulomas and local relapse.

Prenatal sonographic features of triploidy at 12-16 weeks.

The purpose of our study was to describe the sonographic appearance of triploidy in early pregnancy. We report the sonographic characteristics of a cohort of fetal triploid cases detected at targeted ultrasonographic vaginal examinations between 12 and 16 weeks of gestation from 2008 to 2014. Indications for fetal karyotype following ultrasound were maternal request, advanced maternal age, increased nuchal translucency, and/or fetal abnormalities. Triploidy was detected in 25 cases during the 6 years of the study period with an estimated incidence of ~1 in 5000 pregnancies. Four cases had molar changes in the placenta. Among the remaining 21 cases, a consistent sonographic pattern was noted, which included the combination of asymmetric growth restriction with abdominal circumference lagging 2 weeks behind head circumference in 21/21, oligohydramnios in 20/21, abnormal posterior fossa or enlarged fourth ventricle in 20/21, and absent gall bladder in 17/21. Other findings present in more than 50% of cases included cardiac (70%) and renal (55%) abnormalities, clenched hands (55%), and hypoplastic lungs (67%). Fetal triploidy can manifest at 12-16 weeks with molar changes in the placenta or with a cluster of unusual sonographic findings whose presence should prompt appropriate testing for diagnosis in early pregnancy. © 2016 John Wiley & Sons, Ltd.

Pregnancy-Associated Breast Cancer: Significance of Early Detection and Imaging Appearance

Background/Objectives: To evaluate the mammographic and sonographic findings of pregnancy associated breast cancer. Patients and Methods: In this study, we selected 25 patients who were diagnosed with pregnancy associated breast cancer during the previous 10 years. The disease was diagnosed during pregnancy (n = 5) or lactation (n = 20). All patients underwent ultrasonography, the first choice for evaluation of pregnancy associated breast disease. Mammography was performed for 22 patients. Results: The commonest clinical symptom was a breast lump. Ultrasound was abnormal in all cases. The most common ultrasound finding was a solitary hypo echoic mass with irregular shape, irregular margin, and heterogeneous echogenicity. Architectural distortion was seen in two patients. Some unusual sonographic findings for breast cancer were detected in these patients, including parallel orientation, cystic components, and posterior enhancement. Mammography was performed for 22 patients and revealed positive findings in 80% of cases despite a dense breast. The most common mammographic finding was a breast mass with or without microcalcification (n = 10). Microcalcification alone was seen in 2 patients. Lesions, were predominantly invasive ductal carcinoma (96%). Conclusions: Ultrasonography is recommended for the initial diagnosis of pregnancy associated breast cancer. Mammography is indicated when initial evaluation suggests a malignant lesion or when ultrasound is negative in spite of a palpable breast lesion. When the imaging results are suspicious, a biopsy should be performed to obtain a pathologic diagnosis.

Sonographic findings in a fatal case of transient myeloproliferative disorder

Transient myeloproliferative disorder is a unique disease in infants with Down syndrome that typically resolves spontaneously. In this report, we present a fatal case of transient myeloproliferative disorder with unusual sonographic findings including adrenal gland enlargement and thickening of the corpus callosum.

Unusual Sonographic Finding of Metastatic Invasive Lobular Carcinoma to the Contralateral Breast

Invasive lobular carcinoma (ILC) is the second most common breast cancer after invasive ductal carcinoma (IDC), accounting for 5% to 14% of all breast cancers.1 Like other primary breast cancers, ILC can metastasize to a contralateral breast via lymphatic or hematogenous dissemination. However, contralateral breast cancer metastasis is a rare event. A variety of sonographic findings of metastases from extramammary malignancies have been reported, 2 but those from contralateral breast cancer are little known. We report an unusual sonographic finding of contralateral metastases of ILC in a patient with advanced breast cancer and systemic metastases.

An Unusual Imaging and Clinical Presentation of Papillary Thyroid Carcinoma

Papillary thyroid carcinoma is the most common thyroid malignancy, accounting for 88% of all thyroid cancers in the United States.' The most common clinical presentation is a solitary thyroid nodule. On high-resolution sonography, features suggestive of papillary thyroid carcinoma include a hypoechoic solid lesion with microcalcifications and intrinsic vascularity. 2-5 We report an atypical case of metastatic papillary thyroid carcinoma that presented as a left hip mass with unusual sonographic findings of a predominantly cystic primary thyroid lesion.

Unusual sonographic findings in a case of atypical medullary inflammatory carcinoma of the breast

We report the case of a 35-year-old woman who complained of a rapid enlargement of a pre-existing breast mass and yellowish nipple discharge. Clinical examination revealed a firm mass measuring 15 x 10 cm and "peau d'orange" phenomenon. Sonography revealed a well-defined mass with heterogeneous echotexture and hyperechoic trabecular structures that delineated hypoechoic areas, resulting in a honeycomb pattern. The patient underwent a surgical exploration and a biopsy of the mass and of the skin. The histopathologic examination revealed an atypical medullary carcinoma with high mitotic activity.

Pancreatic uncinate carcinoma: sonographic findings.

Pancreatic carcinoma arising from the uncinate process (pancreatic uncinate carcinoma) is relatively rare. We wished to define its clinical manifestations and sonographic findings. Clinical and sonographic data of eight cases were reviewed. The common bile duct and the pancreatic duct were not dilated until a very late stage. The lesion mimicked a mesenteric tumor in two cases. The superior mesenteric vessels were compressed anteriorly. Computed tomography was useful, not only for confirming the pancreatic uncinate origin of the lesion but also for determining precisely the mode of mesenteric vascular involvement. Knowledge of these unusual sonographic findings can determine the diagnostic strategy in pancreatic uncinate carcinoma.
