Posttraumatic pulmonary pseudocyst: Report of two cases

Posttraumatic pulmonary pseudocyst is a rare complication of blunt thoracic trauma. It is commonly seen in pediatric and young adult patients. In the literature, traumatic pseudocysts are also defined as pseudocystic hematoma, traumatic lung cavity and traumatic pneumatocele. Traumatic pseudocysts usually have good clinical prognosis, recover spontaneously with supportive treatment and do not require surgery. In this report, we present rare cases of two posttraumatic pulmonary pseudocysts developed after traffic accidents, where conservative treatment contributed excellent outcomes.

Traumatic Pulmonary Pseudocyst: A Case Report

Post-traumatic pulmonary pseudocyst (TPP) is an uncommon cavitary lesion of the lung. TPP is an air/fluid filled cavity without a true epithelial lining within the pulmonary parenchyma. TPPs usually occur following a motor vehicle accident or fall. Here we report a case of TPP which occurred after blunt chest trauma after a traffic accident. The chest X-ray few hours after the accident revealed mass/cyst like lesion on the right lover zone. Computed tomography of the thorax revealed bilateral cystic lesions on the parenchyma. The patient was treated conservatively with antibiotherapy. He was asymptomatic thereafter, and the traumatic pulmonary pseudocyst radiologically was completely resolved three months later. TPP might be confused with other cystic and cavitary lesions of the lung but radiological rapid onset is important in the differential diagnosis.

Posttraumatic pulmonary pseudocyst

Posttraumatic pulmonary pseudocyst (PPP) is a complication of blunt chest trauma and poorly documented. A retrospective review of PPPs observed during the past 6 years in our hospitals is presented in this report. We retrospectively studied the serial chest computed tomographic scans and clinical data of 33 consecutive patients with PPPs. Fifty-three PPPs from 33 patients were found. Thirty-six PPPs were located in the subpleural pulmonary parenchyma, whereas others were located in the pulmonary parenchyma near other harder structures. Follow-up examinations demonstrated that air-filled cavities and air-fluid cavities could turn into pulmonary hematomas and eventually resolved without specific treatment. The PPPs were resolved in 11 to 82 days. The resolving time of air-fluid cavity (mean, 47.5 days) was significantly longer than the resolving time of air-filled cavity (mean, 16.3 days; p = 0.001). Three patients died of acute respiratory distress syndrome or head trauma. No patient died of PPP. Twelve patients with serious pneumothorax, hemothorax, or both were cured with surgical hemostasis and/or drainage. Eighteen patients resolved without specific treatment. Computed tomography increased the frequency of PPP diagnosis and accurately demonstrated the characteristics of the lesions. Air-filled pseudocysts resolved more quickly than those containing fluid. The outcome of PPPs can be favorable without specific treatment. PPP does not require follow-up CT scan or intervention in the absence of complications. Prognostic/epidemiologic study, level V.

Post-traumatic pulmonary pseudocyst with hemopneumothorax following blunt chest trauma: a case report

IntroductionPost-traumatic pulmonary pseudocyst is an uncommon cavitary lesion of the lung and develops after blunt chest trauma and even more rarely following penetrating injuries. It is generally seen in young adults presenting with cough, chest pain, hemoptysis, and dyspnea. Post-traumatic pulmonary pseudocyst should be included in the differential diagnosis of cavitary pulmonary lesions. We describe the case of a 60-year-old Caucasian Greek woman who sustained traumatic pulmonary pseudocyst with hemopneumothorax due to a blunt chest trauma after a traffic accident.Case presentationAfter a traffic accident, a 60-year-old Caucasian Greek woman sustained a hemopneumothorax due to a blunt chest trauma. There was evidence of an extensive contusion in the posterior and lateral segments of the right lower lobe, a finding that was attributed to an early sign of a cavitation, and the presence of a thin-walled air cavity was detected on the anterior segment of the right lower lobe in the control computed tomography taken 24 hours after admission. Our patient was treated by catheter aspiration, and the findings of computed tomography evaluation about one month later showed complete resolution of one of the two air-filled cavitary lesions. The second pseudocyst also disappeared completely, as shown by the control computed tomography scan performed six months later.ConclusionsTraumatic pulmonary pseudocyst is a rare complication of blunt chest trauma, and computed tomography is a more valuable imaging technique than chest radiograph for early diagnosis.

A Case of Post-Traumatic Pulmonary Pseudocyst Mimicking Pulmonary Cavitary Tuberculosis

,A traumatic pulmonary pseudocyst is a rare complication of blunt thoracic trauma. The clinical symptoms and signs are similar to other respiratory diseases, such as pulmonary tuberculosis. Therefore, a trauma history with the resulting radiologic and clinical findings is important for making a diagnosis. A 26-year-old male was admitted to our hospital due to cough for 3 days. The chest x-ray revealed diffuse infiltrations and a cavitary lesion at the left lung. His left chest had hit a tree as a result of motorcycle accident one day before admission. Initially, it was assumed that his symptoms and chest X-ray might be due to a tuberculosis infection. However, bronchoscopy revealed old blood clots at both lungs, particularly in the left lower lobe bronchus. A transbronchial lung biopsy showed alveolar hemorrhage. A traumatic pulmonary pseudocyst was diagnosed from his trauma history and these findings. Computed tomography of the chest performed 4 months later showed regression of the cavitary lesion.

Nonoperative Management of Post-Traumatic Pulmonary Pseudocyst After Severe Thoracic Trauma and Hemorrhage by Coagulation Management, Kinetic Therapy, and Control of Secondary Infection: A Case Report

Nonoperative Management of Post-Traumatic Pulmonary Pseudocyst After Severe Thoracic Trauma and Hemorrhage by Coagulation Management, Kinetic Therapy, and Control of Secondary Infection: A Case Report

Pulmonale Pseudozysten

Post-traumatic pulmonary pseudocyst is a rare manifestation of blunt thoracic injury. Young adults and adolescents are predominantly affected. Here we report the successful outcome of post-traumatic pseudocysts secondary to severe lung contusion with severe intrathoracic haemorrhage in both lower lobes and the upper right lobe by aggressive coagulation management, kinetic therapy/postural drainage and control of secondary infection.

Posttraumatic Pulmonary Pseudocyst: A Rare Complication of Blunt Chest Trauma

Posttraumatic pulmonary pseudocyst is a rare cavitary lesion lacking an epithelial lining, which develops within the pulmonary parenchyma after blunt chest trauma. Such pseudocysts develop most commonly in children and young adults. The clinical course is usually benign with spontaneous resolution of the radiologic manifestations within 2 to 4 months after trauma. A young male injured in a motor vehicle accident, sustaining a posttraumatic pulmonary pseudocyst, is presented here.

Sentinel Lymph Node (SLN) Biopsy in Clinically Node Positive Disease

2003 management algorithm, because it is quite similar to our own treatment protocol reported in 1989. Although this patient responded to CT-guided drainage, we concur that some are recalcitrant to percutaneous interventions. We also have performed formal lung resection in patients with pneumatoceles unresponsive to minimally invasive procedures, with 25% of patients requiring resection for definitive management in our earlier study. In our experience, there may also be a role for transbronchial decompression to avoid bronchopleural fistulas. Alternatively, in patients undergoing percutaneous drainage who develop persistent bronchopleural fistulas, fibrin glue or Bioglue (Cryolife) might be a therapeutic option before thoracotomy for definitive treatment. In response to Dr Santos’s discussion of nomenclatures, we agree that terminology is important, especially with renewed efforts in and focus on accuracy and patient safety. Assigning appropriate phraseology to this pulmonary parenchymal disruption appears to be confusing for others as well, with only 16 “correct” references in the literature out of 41 articles. Similarly, trauma and critical care texts uniformly use alternate monikers rather than traumatic pulmonary pseudocyst. Even Dorland’s Medical Dictionary recognizes both pulmonary pseudocysts and pneumatoceles. We acknowledge colloquial verbiage often predominates in daily language over proper terminology, but recognize this confusion should be resolved. Our article should be entitled “Posttraumatic Pulmonary Pseudocyst.”

Post-traumatic pulmonary pseudocyst in a 20-year-old man after a motor vehicle accident

INTRODUCTION: Post-traumatic pulmonary pseudocyst (PPP) is an uncommon result of blunt trauma to the chest, presenting as one or more cavitary lesions within the lung parenchyma. We present the case of young man diagnosed with PPP following a motor vehicle accident.

Computed tomography evaluation of posttraumatic pulmonary pseudocysts

Two cases of posttraumatic pulmonary pseudocyst are reported. The characteristic thin-walled cystic lesions with air-fluid level were demonstrated in both cases by computed tomography but in only one case by conventional chest radiography. It is predicted that more such pseudocysts would be identified by using computed tomography with patients with blunt chest trauma.

Post-traumatic pulmonary pseudocyst in the adult: pathophysiology, recognition, and selective management.

Pulmonary contusion is the usual manifestation of lung parenchymal injury following blunt chest trauma. With rapid deceleration, however, parenchymal lacerations can result in cavities best termed post-traumatic pulmonary pseudocyst (PPP). This report discusses eight adult PPP cases encountered at the Denver General Hospital over the past 30 months. Five were males and the mean age was 29 years (range, 18 to 54). Injury mechanism was motor vehicle accident in four, industrial machinery in two, autopedestrian accident in one, and large-animal rodeo rollover in another. Review of daily portable anteroposterior chest roentgenograms revealed parenchymal infiltrates consistent with pulmonary contusion that typically cavitated within the first week. Computed tomography of the chest was pursued in complicated patients and clearly influenced therapy. Three (38%) pseudocysts developed into lung abscesses; two required resection and the other responded to percutaneous drainage. Although previously described as a benign pediatric entity, in our adult experience, PPP may result in a recalcitrant lung abscess requiring aggressive intervention.
