Micronodular thymoma is a rare subtype of thymoma with less than 20 cases published in the English literature. These tumours have been reported with thymoma or thymic cyst. The authors describe a new case of micronodular thymoma in a 68-year-old-patient which is well documented and particular by its cystic degeneration which hasn’t been described yet. Micronodular thymoma is a rare variant of t...

Mediastinal masses are a frequent finding in patients with Hodgkin's disease, and usually represent either mediastinal lymphadenopathy or a diseased thymus gland.1 In some rare patients, however, the mediastinal mass may be due to diffuse thymic hyperplasia2 or benign thymic cysts.3 In each of the 10 reported cases of thymic cysts in Hodgkin's disease, the diagnosis of the thymic cysts was made...

 Abstract Thymic carcinoid is an uncommon neoplasm that can present with Cushing syndrome. We report a 39-year old woman with symptoms of Cushing syndrome secondary to thymic carcinoid and synchronous with tuberculous lymphadenitis and pulmonary tuberculosis. 

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 epidermoid cysts are an extremely rare entity. These arise from epidermal cells that migrate to the thymus. The radiologic diagnosis of this rare lesion is challenging. We describe a case of an otherwise healthy 35-year-old woman who presented with an acute onset of chest pain and shortness of breath. She was found to have an anterior mediastinal mass. The imaging findings were, however,...

The differential diagnosis of a lateral cystic neck mass includes branchial cleft cysts and lymphangiomas. Cervical thymic cysts are rare, and thymopharyngeal duct cysts, which maintain a connection to the pharynx, are rarer still. We present an interesting case of a 6 year-old male who developed acute onset of a left-sided neck mass. CT and MRI findings revealed a multiloculated cyst closely a...

Several types of cysts in the mediastinum have been described, such as bronchogenic or thymic cysts and esophageal duplications, most of which arise in the middle or posterior mediastinum close to the tracheobronchial system or the esophagus. We present herein the rare case of a ciliated cyst anatomically distant to the genitourinary organs. An abnormal formation in the posterior mediastinum wa...

pediatric mediastinal tumors and include thymic cysts, hyperplasia, carcinoma, thymoma and thymolipoma (1). Thymomas are rare tumors of the thymic epithelium with a broad spectrum of morphological and clinical features; they comprise about 1% of mediastinal tumors. Familial occurrence of these tumors has been rarely reported (2-4). We report an unusual familial occurrence of three cases of thym...
