Thymic cysts of the mediastinum are uncommon, accounting
for only 1% to 3% of all mediastinal masses. They
may be congenital or acquired. A left anterior mediastinal
mass was incidentally detected on a chest radiograph of
a 40-year-old asymptomatic man. Computed tomography
showed a cystic mass, 5x6 cm in size. The cyst was totally
resected via left thoracotomy. Histopathologic diagnosis
was made as unilocular thymic cyst. As no etiologic factor
was determined, it was considered a congenital cyst
with atypical features. It had a considerably thick cystic
wall with calcifications; in contrast to congenital unilocular
thymic cysts, the contents of the cyst were not soft in
consistency.
