OBJECTIVE To characterize the CT features of common anterior mediastinal tumors and evaluate CT findings that may help in suggesting specific diagnosis among these tumors. MATERIAL AND METHOD Fifty chest CT studies with pathological diagnosis of thymoma (n=28), mediastinal germ cell tumor (n=14) and lymphoma (n=8) were retrospectively reviewed by two radiologists who were blind to the patholo...

difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. mediastinal masses are not common findings, but are important variables. bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. we present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchoge...

An asymptomatic 26-year-old man received an annual medical check-up, and chest X-ray showed a protrusion of the aortopulmonary window. Chest computed tomography (CT) revealed an anterior mediastinal tumor and cysts with thin wall and septum enhancement. The preoperative diagnosis was cystic thymoma or malignant lymphoma. We performed total resection of the tumor through a median sternotomy. The...

A benign thymic cyst seen six years after valvular heart surgery is described, and the question of the possible role of previous surgical trauma in the development of the cyst is raised.

1 of 2 DESCRIPTION A 75-year-woman with a Duke’s B adenocarcinoma of the caecum underwent a staging CT examination which revealed an oval, 3.6×2.5 cm fl uid attenuation mass (18 Hounsfi eld units) superior to the carina, posterior to the trachea and medial to the oesophagus ( fi gure 1 ). She had no symptoms relating to the mediastinal mass. Radiologically the lesion was thought to be most in k...

Mediastinal bronchogenic cysts are usually identified on computed tomography (CT) as well-defined masses of variable density that may contain rim calcifications. Pleural effusion has never been described in association with these cysts. We report two cases of bronchogenic cysts with unusual presentation because of an association with a pleural effusion not explained by pulmonary infection. The ...

Hydatid disease is a parasitic infection that is remains endemic in many countries, particularly the Middle East and Central Asia. Mediastinal hydatidosis is very rare (less than 0.1% of all hydatid disease cases) that have been only anecdotally in the literature. To the best of our knowledge only one case of multiple mediastineal hydatid cysts has been reported previously. We report the second...

Posterior mediastinal enteric cysts are infrequently reported. They are mostly asymptomatic 1. The incidence of gastroenteric cysts presenting during immediate neonatal period is rare. Alimentary tract duplications are other rare congenital anomalies and are commonly seen in relation to the ileum. However, the high incidence of associated thoracic or cervical vertebral anomalies with foregut cy...
