Posterior interosseus (PI) nerve compression is a rare form of compressive neuropathy. It can cause pain along the radial nerve course and weakness of radial nerve innervating muscles without sensory symptoms. A 65-year-old man visited our institution complaining weakness of finger extension and thumb abduction after 2 times of injections at the right elbow in local clinic. The patient's clinical history and physical examination implied an iatrogenic radial nerve injury caused by the injection. The electrophysiologic study revealed of posterior interosseus neuropathy (PIN) with incomplete conduction block. However, the ultrasound study showed that the PI nerve was compressed by an anechoic cyst. The magnetic resonance imaging also confirmed of a ganglion cyst, not a hematoma. After repeated aspirations and a steroid injection, the electrophysiologic study showed recovery of motor weakness. Despite of the clue which implying an iatrogenic injury, clinician should consider other possibilities such as ganglion cysts and ultrasound guided aspiration and steroid injection could be an effective option for conservative management.

지방종은 가장 흔한 양성 종양이지만, 심부 조직에 발생하는 방골성 지방종은 매우 드문 질환이다. 저자들은 근위부 요골에 발생하여 후골간 신경마비를 일으킨 방골성 지방종 1례를 경험하였다. 53세 남자 환자가 3주전부터 발생하여 지속된 우측 수근 관절 및 수지의 신전 제한을 주소로 본원을 방문하였다. 검사 결과 방골성 지방종으로 확진되었고, 수술 6개월 후 증상 회복되어 정상적인 운동이 가능하였다.
