Abstract：
Juxta-articular myxoma (JAM) is a rare soft tissue tumour predominantly composed of mucinous tissue and usually found around large joints. We report a 73-year-old woman with a 5-year history of a soft tissue mass in the thenar eminence of the right wrist who presented to our department. An initial diagnosis of a ganglion cyst was made using magnetic resonance imaging (MRI) and the jellied content of the mass by aspiration. Two years after presentation, surgical treatment with tumour resection and carpal tunnel release via the radial approach was performed because the symptoms of carpal tunnel syndrome worsened, and the tumour invaded the carpal tunnel. Histopathological examination revealed a JAM. At the 1-year follow-up, the symptoms of carpal tunnel syndrome had resolved, and no recurrence was confirmed by MRI. Level of Evidence: Level V (Therapeutic).
摘要：
近关节粘液瘤（JAM）是一种罕见的软组织肿瘤，主要由粘液组织组成，通常在大关节周围发现。我们报告了一名73岁的女性，她有5年的右手腕大脑皮层软组织肿块病史，她向我们部门介绍。神经节囊肿的初步诊断是使用磁共振成像（MRI）和抽吸肿块的胶状内容物进行的。演讲两年后，由于腕管综合征的症状恶化，通过放射状入路进行了肿瘤切除和腕管松解术。肿瘤侵入腕管.组织病理学检查发现JAM。在1年的随访中，腕管综合征的症状已经消退,MRI证实无复发。证据等级：V级（治疗）。
