急速に増大し緊急手術となった気管支原性囊胞の1例

Bronchogenic Cyst with Rapid Increase and Emergency Operation；Report of a Case

はじめに　縦隔原発気管支原性囊胞は経過が長期に及び，症状が出現した後では高度癒着のため治療に難渋する場合がある．われわれは急速に増大した気管支原性囊胞に対し緊急手術を行ったが，癒着のため摘出に難渋した1例を経験したので報告する．

A 21-year-old man was admitted with fever and back pain. Chest computed tomography （CT） showed a cystic mass of 7×6 cm in the right middle mediastinum. After 3 days, symptoms worsen, and chest X-ray revealed the enlargement of the cyst, and an emergent operation was performed. Since the tumor was severely adhered to the superior vena cava and the azygous vein, the cystic mass was partially resected. The pathological diagnosis was bronchogenic cyst.
