Cervical thymic cyst is uncommon and usually occurs in the first and second decades. Cervical thymic cyst after the third decade is so rare that it is very difficult to diagnose in spite of its typical location. We present a rare case of cervical thymic cyst in the lower left - anterior of the neck in a 50-year-old woman. It showed well-defined, anechoic cyst on ultrasonography and non-enhancing low attenuation mass on CT. A typical anatomic relationship was noted between the mass and carotid sheath.

A thymic cyst in the middle mediastinum adjacent to the right pericardium is extremely rare. We report a case of a large thymic cyst in the right cardiophrenic angle, compressing the right atrium, which was presented as a cardiomegaly on the chest radiograph and a pericardial cyst on the echocardiography. The definitive diagnosis was confirmed using surgical resection and biopsy.

We experienced a case of a tracheoesophageal cyst in the posterior mediastinum of a three-year-old girl, who complained of cough and fever. We confirmed this case by computerized tomography and pathologic examination after surgical resection. A brief review of the literature is presented.

We report a very rare case of mediastinal tuberculosis in a 57-year old woman who presented with a large mediastinal cyst on chest radiography. She had a 10-year history of exertional dyspnea, but felt comfortable at a rest. A subsequent chest CT suggested a mediastinal cyst with mediastinal lymphadenopathy and communicating pericardial sac. She underwent a thoracotomy and excision of the mass, which was histologically revealed to be of tuberculous origin. Although rare, the apparent increase in the incidence of tuberculosis may result mediastinal cysts being diagnosed mediastinal tuberculosis. We also briefly review mediastinal lymphadenopathy due to tuberculosis.

Lymphangioma is a congenital abnormality of the lymphatic system detected primarily in early childhood. There are rare reports of mediastinal lymphangioma in older adults. We hereby report on a 66-year-old female patient who underwent kidney transplantation 20 years previously and who developed pathologically confirmed solitary mediastinal lymphangioma 1 year ago. Chest radiography showed a mediastinal nodule, which was not observed 2 year previously, therefore she was referred to the pulmonary division. She had no symptoms, and chest computed tomography demonstrated a 25-mm, well-defined, low-density nodule located at the anterior mediastinum. The size of the nodule had increased from 25 mm to 34 mm 1 year later, and it was completely resected via video-assisted thoracic surgery. The histological diagnosis was cystic lymphangioma. Therefore, we recommend that clinicians consider cystic lymphangioma as a possible diagnosis even in older patients with a mediastinal cystic mass that shows progressive enlargement.

CT provides a valuable new perspective in assessing abnormalities of the thorax. In patients with amediastinal mass or widening detected by plain chest radiography, a definite diagnosis is sometimes possible whichwould not obtainable by conventional radiological technique. Clinical staging of bronchogenic carcinoma can beachieved by CT better than any other radiologic method. In fifty patients with histologically or angiographically confirmed disease of the thorax,an analysis of chest radiography and chest CT manifestations was made, and theresults were as follows; 1. 27 patients with mediastinal mass detected by chest radiography, a definite diagnosiswas possible in 10 patients (36%), who were 6 with teratodermoid, 1 with thymic cyst, 3 with aneurysm. In allpatients, the extent and localization of mediastinal mass could be established more precisely than by the chestradiography. 2. In 15 patients wtih bronchogenic carcinoma, 9 patients (60%) showed hilar adenopathy ormediastinal adenopathy which could not be noted on the chest radiography. 3. Main CT findings of braonchogeniccarcinoma were peripheral lung mass, spiculated or lobulated margin, adhesion to pleura or chest wall, andatelectasis or chronic pneumonia. 4. Commonly observed CT findings of teratodermoid were well capsulated mass,calcification, fat density , and multi-loculation. 5. Commonly observed CT findings of thymoma were homogenousmass, round contour, partially preserved mediastinal fat. CT was superior in evaluation of mediastinum and in the detemination of the extent of known bronchogenic carcinoma.
