OBJECTIVE AND METHODS In order to clarify the utility of video-assisted thoracoscopic surgery (VATS) for mediastinal disease, we analyzed retrospectively 34 thoracoscopic surgical cases (seven lymph node, nine thymic, eight cystic and 10 cases with solid lesions that excluded thymic diseases) between February 1993 and July 2002. RESULTS In lymph node disease, adequate specimens were obtained ...

Multilocular thymic cyst (MTC) and germ cell tumors are common diseases that impact the mediastinum. Correctly diagnosing these can be difficult because several other conditions mimic them. We report a male patient with MTC associated mediastinal seminoma. A needle biopsy of tumor revealed numerous epithelioid granulomas mimicked sarcoidosis or mycobacterial infection. However, large atypical c...

The clinical, MR imaging, surgical, and histologic findings in two cases of cystic aberrant cervical thymus were reviewed. Aberrant cervical thymic tissue was sharply circumscribed and extended deep to the posterior pharyngeal wall at the level of the piriform sinus in both cases. Both lesions had cyst contents that were of increased signal intensity on T1-weighted images. Solid components disp...

Patient was referred to our Service with acute thoracic pain and diagnosis of intramural hematoma of the ascending aorta for surgical correction. The diagnostic investigation showed a cystic tumor involving the ascending aorta causing restriction of the right ventricular inflow. After resection, the histologic analysis disclosed the diagnosis of thymic cyst. The aim of this study is to describe...
