Primary mediastinal adenocarcinoma is rare, but its originating from a calcified nodule is even more unusual. We present herein a 55-year-old female with a superior mediastinal mass, first discovered 2 years prior that changed dramatically from its original appearance as a calcified nodule. The mass was completely resected, and histopathological examination revealed a primary adenocarcinoma. Th...

Thymomas are the most common type of mass found in adult anterior mediastinal masses. Thymomas typically metastasize to the ribcage because of their slow growth and affinity for local invasion. Far metastases are rare, with the brain as the most commonly metastasized area. Bone metastases of thymomas are usually observed in the calvarium. A 60-year-old patient, who presented with metastatic mas...

Primary cranial mediastinal hemangiosarcomas are uncommon tumors. A 30-kg, 2-year-old, intact female German shepherd was presented for evaluation of cachexia and respiratory distress of a few days' duration. Lateral radiographic projection of the thorax revealed significant pleural effusion. Computed tomography revealed a cranial mediastinal mass effect adjacent to the heart. On surgical explor...

OBJECTIVE To describe a rare case of occult (<1 cm in diameter) medullary thyroid carcinoma (MTC) in a 45-year-old woman, presenting as an asymptomatic mediastinal mass. DESIGN The diagnostic methodology included laboratory measurements of relevant biochemical and hormonal parameters including calcitonin (CT), carcinoembryonic antigen (CEA) and chromogranin A, and imaging techniques including...

We read with great interest the presentation by Lindblom et al. [1] regarding an an-eurysm of the left internal mammary artery (IMA), which is a rare and potentially devastating pathology. The case presented has diagnostic challenges and a spontaneous rupture resulting in life-threatening bleeding. The authors suggested the importance of the careful interpretation of radiological findings and t...

We report a 35-year-old gentleman who presented to us with respiratory distress. He was diagnosed to have a large anterior mediastinal mass and was and posted for debulking of mediastinal mass. Immediately after intubation, airway collapsed and there was difficulty in ventilating the lungs, followed by drop in oxygen saturation. After sternotomy, oxygen saturation and airway pressures improved....

A parathyroid lipoadenoma is a very rare cause of mediastinal mass. The clinical features of this pathologic entity is similar to those of the more common pathologic variants of parathyroid disease associated with primary hyperparathyroidism. A 58-year-old woman presented with huge multinodular goiter. Her thoracic CT scan was done before surgery, showed a posterior mediastinal mass. On microsc...
