外傷性sinus pericraniiの1例

A Case of Traumatic Sinus Pericranii

Ⅰ．はじめに

　1850年にStromeyerが，頭蓋内静脈系と頭皮下静脈系の交通による頭皮下静脈性腫瘤をsinus pericraniiと報告して以来，報告が散見される．今回われわれは，左前頭部の陥没骨折後に発生した外傷性sinus pericraniiを経験したので報告する．

Sinus pericranii is a rare vascular anomaly involving an abnormal communication between the extracranial and in-tracranial circulations. A 33-year-old woman presented with a soft tissue mass at the left frontal region. It was associ-ated with head trauma when she was 12-year-old. The mass had gradually grown and become painful for 20 years. She underwent surgical resection of the mass successfully. This report discusses traumatic sinus pericranii.
