Lipofibromatous hamartoma (LFH) is an extremely rare benign tumor, which is characterized by an excessive infiltration of the epineurium and perineurium by fibroadipose tissues.A 27-year-old woman was diagnosed with left carpal tunnel syndrome (CTS) due to (LFH) of the median nerve. LFH was diagnosed by MRI and sonography; the characteristic ultrasonographic feature of LFH showed a good correlation with pathognomonic MRI findings. The median nerve was involved along its course in the forearm; however, the patient needed carpal tunnel release because of severe compression of the median nerve under the flexor retinaculum.Radiologic evaluation of patient with CTS to evaluate probable secondary CTS is recommended.
脂肪纤维瘤性错构瘤（LFH）是一种极为罕见的良性肿瘤，其特征是纤维脂肪组织过度浸润神经外膜和神经束膜。一名27岁女性因正中神经的LFH被诊断为左腕管综合征（CTS）。LFH通过磁共振成像（MRI）和超声检查确诊；LFH的特征性超声表现与典型的MRI表现具有良好的相关性。正中神经在前臂走行过程中受累；然而，由于屈肌支持带下正中神经严重受压，患者需要进行腕管松解术。建议对CTS患者进行影像学评估，以评估可能的继发性CTS。
