Abstract

Intraneural hemangioma of the median nerve is extremely rare. Only a few cases have been reported in literature. The researchers present ultrasound (US) and MRI findings of a case of 38-year-old-man with intraneural capillary hemangioma of the median nerve. The patient had a small, palpable mass in the volar aspect of the wrist and symptoms of carpal tunnel syndrome. US showed an infiltrative intraneural mass, without significant blood flow despite a compression test. The researchers initially misdiagnosed this mass as an in-continuity neuroma. The mass showed heterogeneous, but predominantly high signal intensity on T2-weighted image, as well as heterogeneous enhancement. The MRI findings were helpful for correct diagnosis on the retrospective review.

정중신경 내 혈관종은 매우 드물며, 적은 수의 증례만이 보고되어 있다. 저자들은 38세 남자환자에서 생긴 정중신경 내 모세혈관종의 초음파 및 자기공명영상 소견을 보고한다. 환자는 손목 바닥 부위에 만져지는 작은 종괴와 손목굴증후군 증상으로 내원하였다. 초음파검사에서 혈류증가를 동반하지 않는 침윤성 신경 내 종괴가 보였고, 저자들은 연속성 신경종으로 오인하였다. 종괴는 T2강조영상에서 불균질하지만 전체적으로 고신호강도를 보였으며, 불균질하지만 조영증강이 잘되는 소견을 보였고, 이러한 자기공명영상 소견은 영상소견을 재검토 하였을 때 모세혈관종을 올바르게 진단하는 데 도움이 되는 소견으로 생각된다.
