気管支内に発生した過誤腫の1例

A case of endobronchial hamartoma

肺過誤腫は，ほとんどが肺野に発生するものであるが，まれに気管・気管支内にも発生する。今回我々は，CTで内部に脂肪濃度を認めた気管支内過誤腫の1例を経験したので，文献的考察を加えて報告する。

Lung hamartomas are mostly localized in the peripheral lung, and endobronchial hamartoma is relatively rare. Characteristic CT findings include a lesion with smooth edges, focal collections of fat, or collections of fat alternating with foci of calcification. Here we present a case of endobronchial hamartoma, which CT typically showed as a fatty lesion.
