Extrapulmonary sequestration (EPS) is a rare congenital anomaly usually diagnosed during the first six months of life. It is mostly found between the left lower lobe of the lung and the diaphragm. Mediastinal presentation is extremely rare. We describe two identical cases of extrapulmonary sequestration mimicking mediastinal cystic mass in two boys. These emphasize the need to keep this diagnos...

We report a rare case of bronchogenic cyst associated with congenital complete absence of the pericardium. A 17-year-old male was admitted to the hospital for surgical resection of a growing cystic lesion located in the middle mediastinum. The patient was asymptomatic and no significant findings were found on physical examination. Resection of the mediastinal cyst was performed by video-assiste...

A 35-year-old Japanese man's routine chest radiography revealed an abnormal opacity. Chest computed tomography and magnetic resonance imaging showed a 5.5 cm in dia. cystic tumor located at the left anterior mediastinum. The tumor was suspected to be an asymptomatic thymic cyst, and we chose observation for the tumor. At the 3-year follow up, the cystic tumor had gradually enlarged to 7.5 cm in...

UNLABELLED Teratoma is a rare cause of thyrotoxicosis. Among the different types of teratoma, struma ovarii is the main type which contains thyroid tissue. There is no evidence in the literature that would indicate mediasternal teratoma would also lead to thyrotoxicosis or thyroid storm. Herein we report a 37-year-old woman who suffered from palpitation. Her chest X-ray showed a mass lesion at ...

Transbronchial fine needle aspiration (TBFNA) was used to confirm the diagnosis of bronchogenic cyst in two asymptomatic patients with mediastinal masses who declined surgical exploration. Both masses were located subcarinally but differed in computed tomographic density (7 and 59 Hounsfield units). Aspirate cytology demonstrated predominately bronchial columnar epithelial cells in mucus, witho...

Pericardial cysts frequently are recognized when they present in a cardiophrenic angle, but may not be suspected when they occur elsewhere in the chest. To highlight the unusual presentations of pericardial cysts, we present two patients with cysts in the upper mediastinum and review the reported experience with similar lesions. Our patients' cysts are particularly instructive because one cyst ...

Cervical thymic cysts are among the rarest cysts found in the neck. Nests of thymic tissue may be found anywhere along the descent of the thymic primordia from the angle of the mandible to the mediastinum. Mediastinal extension is seen in 50% of cervical thymic cysts. The author report an uncommon case of a 27-year-old female , who noted a painless, growing mass on his neck of two -year duratio...

CONTEXT Pancreatic pseudocysts located in the mediastinum are rare. Symptomatic mediastinal pseudocysts can present with dysphagia, dyspnea, airway obstruction and/or cardiac tamponade. Generally, the standard approaches are surgery and external drainage. Recently, there have been many reports of successful endoscopic drainage mainly using a transpapillary technique. However, there have only be...

Pericardial cysts are rare mediastinal cysts, which are commonly asymptomatic. We report the case of a middle-aged lady, with a previous short history of chest pain, who was found to have a focal pericardial density, felt to have been a consequence of haemorrhage into such a cyst.
