Pericardial cyst is an uncommon congenital mediastinal tumor. The majority of pericardial cysts are located in the right cardiophrenic angle, but rarely they can be located intrapericardially. We now present a case of a huge intrapericardial pericardial cyst excised with video-assisted thoracoscopic surgery.

Mediastinal fibrosis is uncommon but may result in entrapment and erosion of vital mediastinal structures by fibrous tissues. Idiopathic mediastinal fibrosis involved esophagus is very rare, and only a few cases have ever been reported. Such idiopathic mediastinal fibrosis involved esophagus is an enigmatic inflammatory fibrous tissue proliferation, but the treatment has not yet been clearly defined. We had successfully treated in such a case with partial esophagolysis and esophagomyotomy.

Bronchogenic cysts (BCs) are relatively common congenital anomalies in the mediastinum. Most of the patients with BC can be managed both safely and effectively by minimally invasive methods. Selected patients with a BC in a favorable location can have the cyst partially or completely excised by mediastinoscopic techniques. Herein we report on a case of a left lower paratracheal bronchogenic cyst that was completely resected by a video-assisted mediastinoscopic technique, and we discuss the technical aspects of this procedure.

The pneumomediastinum after a dental treatment occurs rarely and shows almost good prognosis, however it is potentially life-threatening complication. Here we report a case of pneumomediastinum, occurred by air bubbles originated from dental high speed equipment, via head and neck fascial space with literatures review.

We present herein an unusual case of multilocular thymic cyst, with prominent lymphoid follicular hyperplasia, in a 64-year-old man. It was incidentally founded as a mediastinal mass on chest radiography, during a routine health check-up. Computed tomography revealed a cystic lesion, which contains thick septa involving the thymus. The resected mass, 8x4 cm in diameter, involved the thymus and there is no adhesion or invasion into the adjacent tissue. The cut surface showed cystic spaces with thick white-tan firm wall, which cysts contained gelatinous material. Microscopically, the lesion was characterized by multiple cysts, lined by flattened cuboidal epithelium that was separated by thick walls, having a dense lymphoid tissue with lymphoid follicles. The patient was discharged without any complication and is well without evidence of recurrence for sixteen months.

With advancement of the technique of video-assisted thoracic surgery (VATS), some surgeons have made great efforts to reduce the number of incisions in the conventional three- or four-port approach. Several studies on cases treated by single-incision VATS and their short-term outcomes were reported. Here, we present our experience with single-incision VATS for the treatment of benign mediastinal diseases.

A 47-year old woman was admitted to our hospital for removal of a known mass that was located on the suprasternal notch; specifically, the mass was located on the supero-anterior mediastinuum. The mass was removed by a cervical incision and the histopathologic diagnosis of the resected specimen was hererotopic thyroid tissue with nodular hyperplasia. Mediastinal hererotopic thyroid tissue is a rare malady, so we report here on a case of mediastinal hererotopic thyroid tissue and we review the relevant medical literature.
