Myoepitheliomas are rare tumors increasingly recognized to occur in the soft tissues. Although the hand and carpal tunnel are exceptional locations, the presence of these lesions in such sites constitutes a potential cause of debilitating symptoms. We report the case of a patient with severe pain secondary to median nerve compression and displacement of flexor tendons caused by a rapidly growing myoepithelioma. This is the first sonographic description of this tumor producing carpal tunnel syndrome and disabling pain. High-resolution sonography allowed evaluation of gross tumor morphology and real-time assessment of its interactions with surrounding structures.
肌上皮瘤是一种罕见的肿瘤，越来越多地被认为发生于软组织中。尽管手部和腕管是其罕见的发病部位，但这些部位出现此类病变可导致使人衰弱的症状。我们报告了一例患者，其因快速生长的肌上皮瘤导致正中神经受压和屈肌腱移位而出现剧痛。这是关于该肿瘤导致腕管综合征及致残性疼痛的首例超声描述。高分辨率超声能够评估肿瘤大体形态，并实时评估其与周围结构的相互作用。
