Carpal tunnel syndrome is one of the most common conditions affecting the hand. The majority of cases are idiopathic, with tumours causing less than 3% of cases. We present a unique case of an angiolipoma overlying the carpal tunnel as a cause of median nerve compression. A 54-year-old female presented with signs and symptoms consistent with carpal tunnel syndrome associated with an enlarging lump overlying the carpal tunnel on the palmar surface of her hand. Nerve conduction studies confirmed median neuropathy. The case was successfully treated by surgical excision of the tumour and open carpal tunnel release. Histopathology confirmed the presence of an angiolipoma. The patient had complete resolution of symptoms at the final 6-week follow-up. This case highlights the importance of considering tumours in the differential diagnosis of carpal tunnel syndrome.

血管脂肪瘤：腕管综合症的独特原因

腕管综合症是影响手部的最常见疾病之一。大多数病例是特发性的，肿瘤引起的病例不到3％。我们介绍了一个独特的案例，血管脂肪瘤覆盖在腕管上，是正中神经受压的原因。一名54岁的女性表现出与腕管综合症相符的体征和症状，伴有手掌表面腕管上方肿大的肿块。神经传导研究证实中位神经病变。通过外科手术切除肿瘤并开放腕管松解术成功治疗了该病例。组织病理学证实存在血管脂肪瘤。在最后的6周随访中，患者的症状已完全缓解。
