Tarsal tunnel syndrome (TTS) is a compression neuropathy of the posterior tibial nerve in the ankle, commonly caused by a mass lesion such as ganglion, tumor, fracture, or post-traumatic fibrosis. Although anomalous muscle is relatively common in the ankle, there has been only one report to date implicating it in TTS. This case demonstrates MR findings of a strained flexor digitorum accessorius longus muscle as an unusual cause of TTS.
跗管综合征（TTS）是一种踝关节胫后神经受压的神经病变，通常由诸如腱鞘囊肿、肿瘤、骨折或创伤后纤维化等肿块病变引起。虽然异常肌肉在踝关节相对常见，但迄今为止仅有一份报告表明其与跗管综合征有关。本病例展示了异常的拇长屈肌劳损作为跗管综合征罕见病因的磁共振成像表现。
