Mediastinal teratoma is an infrequent germ cell tumour and comprises of 1 to 5% of all mediastinal tumours. We report a case of mediastinal mature teratoma in a 12 year old boy who presented to us with persistent non-productive cough, fever and dyspnoea for the past 7 months. Computed tomographic scan of thorax revealed a large anterior mediastinal mass measuring 11.2x9.9x14cm with calcificatio...

The second documented case of mediastinal ectopic tissue presenting as a mediastinal mass is reported. Previously reported cases of ectopic pancreatic tissue in the thorax are reviewed in an attempt to explain this anomalous development.

A case of a middle mediastinal mass which proved to be a thymoma is presented. The diagnostic difficulties that middle mediastinal masses produce and the investigations used to delineate them are discussed.

malignant peripheral nerve sheath tumor (mpnst) is a rare nerve sheath tumor derived from schwann cells or pleuripotent cells of neural crest. neurogenic tumors make about 10-20% of all mediastinal tumors. incidence of mpnst is 0.001% in general population and 0.16% in patients with neurofibromatosis i (nf i). we report a case of 60 year female presenting with progressive cough and breathlessne...

Imaging-guided percutaneous chest biopsy is a commonly performed procedure and considered the minimally invasive gold standard for histopathological investigation of thoracic masses. Recognized complications include pneumothorax, air embolism, and seeding of the biopsy tract. We describe a novel approach to diagnostic sampling of a mediastinal mass in a critically unwell patient using a transju...

Although mature teratomas are a common cause of anterior mediastinal tumors, they rarely arise in other mediastinal compartments. We describe a 16-year-old boy with a 20×10 cm mature cystic teratoma in the posterior mediastinum. This case emphasizes the importance of correct diagnosis if a mediastinal mass with the typical features of a mature teratoma-such as fat, cystic compartments, calcific...

INTRODUCTION Mediastinal schwannomas are typically benign and asymptomatic, and generally present no immediate risks. We encountered a rare case of a giant benign posterior mediastinal schwannoma, complicated by life-threatening cardiac tamponade. CASE PRESENTATION We report the case of a 72-year-old Japanese woman, who presented with cardiogenic shock. Computed tomography of the chest reveal...

Secondary transformation in Germ Cell Tumours (GCT) is an extremely rare event. We report here a case of malignant melanoma arising in primary mediastinal GCT. A young male presented with new onset dyspnoea and a mediastinal mass. As serum alpha fetoprotein was raised, a diagnosis of primary mediastinal GCT was made. He achieved remission with standard chemotherapy and resection of the mass. Af...

Sarcoidosis is a somewhat common pulmonary disease, but the concurrence of lung cancer and sarcoidosis in the same patient is very rare. Because sarcoidosis usually presents as mediastinal lymphadenopathies, this concurrence in a lung cancer patient detected radiologically is apt to be misunderstood to be mediastinal metastases, and it is thus considered to be an unresectable disease. We report...
