The patient was a 59-year-old woman in whom computed tomography revealed a posterior mediastinal cyst and ovarian cystoma at a medical check-up in March 2007. Blood tests showed high CA19-9 and CA125 levels. She underwent left adnexectomy for ovarian cystoma in July 2008 and histopathological examination led to a diagnosis of dermoid cyst. The postoperative levels of CA19-9 and CA125 remained h...

Congenital cysts are typically unilocular and thin-walled to the point of translucency; careful histopathologic examination shows no evidence of inflammation. In contrast, acquired thymic cysts are usually multilocular, hence the commonly used term “multilocular thymic cyst (MTC).” These cysts have thick, fibrous walls, and histopathologic examination typically reveals significant inflammation ...

Pericardial cysts are rare mediastinal abnormalities, which are usually congenital but may also be acquired after cardiothoracic surgery. Cysts frequently occur in the right cardiophrenic angle and their diagnosis is usually suspected after an abnormal chest X ray is obtained. The presence of a pericardial cyst in this typical location or, less frequently, in an unusual location, poses a diagno...

A 14-year-old male was found to have a mediastinal mass on chest radiograph. Chest computed tomography scans showed a cystic lesion behind the left main bronchus. Magnetic resonance imaging revealed additional cystic lesions in the left chest and root of the neck. He underwent excision of mediastinal mass and a pleural cyst. The neck lesion was presumed to be a cystic hygroma. Histological exam...

INTRODUCTION Congenital thymic cyst (CTC) is a rare mediastinal mass and the retrocaval position of this cyst has not been reported in the medical literature so far. CASE PRESENTATION The present study reports on a 66-year-old female with coronary artery disease (CAD) who was scheduled for coronary artery bypass grafting (CABG) at our hospital. During mediastinal exploration and pericardiotom...
