The authors report a case of tumour of the right iliac region in a 14 years old girl, disclosed by a light traumatism, without appreciable antecedents, nor locomotor disfunction. Ultrasonography and computed tomography showed its cystic constitution. Surgically, there was a synovial cyst of the ilioinguinal area, cyst of the iliopsoas bursa, with a hip joint communication. It was resected and a partial recurrence occurred, corrected surgically three years later. A recent MRI showed the spontaneous development of a same cyst on the left side, asymptomatic at all. A non exhaustive survey of literature confirmed the iliopsoas synovial bursa is uncommonly pathologic, but a constant natural formation in man. Pathology occurs only in over sixty years old adults. This case seems to be the first pediatric case. The cyst of the psoas bursa is generally revealed by an inguinal swelling; abdominal growing is rare. Imaging with ultrasonography, computed tomography and RMI such as in this case, showed the cyst issued between the coxofemoral joint and the iliac psoas terminal tendon. It can grow in a retroperitoneal way. Pathogenic hypothesis are debated. In this bilateral case, etiology evoke an anatomic anomaly, in relation a joint communication.
作者报告了一名14岁女孩右髂区肿瘤的病例，该病例由轻度创伤发现，无明显既往史，也无运动功能障碍。超声检查和计算机断层扫描显示其为囊性结构。手术中发现为髂腹股沟区滑膜囊肿、髂腰肌滑囊囊肿，并与髋关节相通。囊肿被切除，但三年后出现局部复发并再次接受手术矫正。最近的磁共振成像显示左侧自发出现了一个相同的囊肿，完全无症状。对文献的非详尽检索证实，髂腰肌滑膜囊很少发生病变，但在人体中是一种常见的自然结构。病变仅发生在60岁以上的成年人中。该病例似乎是首例儿科病例。腰大肌滑囊囊肿通常表现为腹股沟肿胀；腹部生长较为罕见。如本病例中通过超声、计算机断层扫描和磁共振成像进行的影像学检查显示，囊肿位于髋关节和髂腰肌终腱之间。它可以呈腹膜后生长。关于致病假说存在争议。在这个双侧病例中，病因引发了一种与关节相通有关的解剖异常。
