We report the case of a 10-year-old girl with a soft tissue aneurysmal bone cyst (STABC) located in the posterior aspect of the left shoulder. Conventional radiography revealed an oblong mass with a calcified rim. On the computed tomography scan, the lesion appeared to have a non-uniform intralesional density with an incomplete rim. Magnetic resonance imaging revealed a multi-cavity lesion with fluid-fluid levels. Following pathological examination, the lesion was diagnosed as a STABC. This may be only the twentieth reported case in the English literature of this extremely rare benign tumor occurring in soft tissue. Eight months after surgery the patient was assessed at our outpatient clinic and found to have excellent mobility of her left shoulder and no sign of recurrence.
我们报告了一例10岁女孩的病例，其软组织动脉瘤样骨囊肿（STABC）位于左肩后部。传统X线摄影显示一个有钙化边缘的椭圆形肿块。在计算机断层扫描上，病变显示内部密度不均匀，边缘不完整。磁共振成像显示一个有多腔且有液-液平面的病变。经过病理检查，该病变被诊断为STABC。这可能是英文文献中报道的这种极其罕见的发生于软组织的良性肿瘤的第20例。手术后八个月，患者在我们的门诊接受评估，发现左肩活动度极佳，无复发迹象。
