Introduction. 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. Case Report. We report an uncommon case of a 15-year-old male, who noted a painless, growing mass on left side of his neck ...

Branchial pouch-derived anomalies may arise from remnants of the first, second, or third/fourth branchial arches. Branchial pouch-related structures are found within the thyroid gland in the form of solid cell rests, epithelial lined cyst with or without an associated lymphoid component, thymic and/or parathyroid tissue, and less commonly in the form of heterotopic cartilage. We present a rare ...

Thymic adenocarcinoma of the mediastinum is extremely rare. Only 12 cases adenocarcinoma associated with a thymic cyst have been reported in the literature. In this report, we describe a case of a thymic adenocarcinoma associated with thymic cyst. A 70-year-old man, presented with two months of chest tightness, breath shortness and chest pain. The contrast enhanced CT scan of chest revealed a r...

We present a case of a 6 year-old boy who presented with a huge mass in the right side of the neck and changes its size with respiration and with straining. Computed tomography of the chest and neck showed a huge mass that was thought to be cystic hygroma. It was excised by both median sternotomy and a right cervical incision. Pathology revealed a thymic cyst.

Thymic cysts occur relatively rarely and account for only about 3% of all anterior mediastinal masses. 1 Although thymic cysts usually grow very slowly, there have been three reported cases of unilocular thymic cysts that enlarged rapidly as a result of intra-cystic haemorrhage: two cases occurred in children with aplastic anaemia and one occurred in a 13 year old boy with no other symptoms. 2 ...

A 58-year-old man who had been undergoing treatment for chronic pericarditis for 15 months was found to have a calcified mediastinal mass shadow on a chest X-ray and was referred to us for further study and treatment. Chest computed tomography and magnetic resonance imaging showed an anterior mediastinal multilocular tumor with rim calcification. Tumor markers were within normal limits. The pat...
