Parosteal lipoma of the proximal radius is a benign, slow-growing tumor. It may cause compression of either the posterior interosseous or the superficial branch of the radial nerve. Surgical excision usually leads to complete recovery. Five cases of parosteal lipoma of the proximal radius are presented. X-ray films demonstrated a radiolucent mass in contact with the radius. Two patients had signs of posterior interosseous nerve compression, and two showed signs of superficial radial nerve compression. In one case the lipoma surrounded an exostosis arising from the proximal radius. The tumors were excised in four patients. The three patients with neurologic involvement recovered fully. One patient refused surgery, and posterior interosseous nerve paralysis developed.
桡骨近端骨旁脂肪瘤是一种良性、生长缓慢的肿瘤。它可能会压迫骨间后神经或桡神经浅支。手术切除通常可导致完全康复。本文报告了5例桡骨近端骨旁脂肪瘤。X线片显示与桡骨相邻的透光性肿块。2例患者有骨间后神经受压体征，2例有桡神经浅支受压体征。1例脂肪瘤围绕着桡骨近端长出的骨疣。4例患者的肿瘤被切除。3例有神经受累的患者完全康复。1例患者拒绝手术，随后出现了骨间后神经麻痹。
