The aneurysmal bone cyst is a benign rare tumor, which usually develops during childhood and its more often found in limbs. The most accepted treatment consists in curetagge and filling with graft. However, certain locations may be inaccesible for surgery and represent therapeutical challenges. We present the case of an 11 year-old male patient with limping and right hip pain without any traumatic nor infectious record. In the image studies with CT and MRI a lytic and expansive lession was found in the upper part of the right acetabulum and right iliac wing, all of which suggested an aneurysmal bone cyst with an associated acetabular fracture. A biopsy was performed which confirmed the diagnosis. He was treated with a CT-guided embolization and, due to its size, curetagge and allograft filling afterwards. He was asymptomatic after1 year of follow-up.
动脉瘤样骨囊肿是一种罕见的良性肿瘤，通常在儿童期发病，多见于四肢。目前最常用的治疗方法是刮除病灶并植入骨移植材料。然而，某些部位手术难以触及，构成了治疗挑战。我们报告一例11岁男性患者，跛行伴右髋疼痛，无任何创伤或感染史。CT和MRI影像学检查发现右髋臼上部和右髂骨翼有溶骨性、膨胀性病变，提示为动脉瘤样骨囊肿伴髋臼骨折。活检确诊。患者先行CT引导下栓塞治疗，因其病灶大小，随后行刮除术及同种异体骨填充。随访1年后患者无症状。
