Unicameral bone cysts of the pelvis are extremely rare. This study summarizes the clinical, radiologic and pathologic features of 16 cases. Patients ranged in age from nine to 69. Most lesions were in the anterior portion of the iliac wing; many appeared to be related to an open iliac crest apophysis. This suggests that the pathogenesis of unicameral bone cysts in this portion of the ilium is similar to that seen in the proximal humerus and the proximal femur. The correct diagnosis was made preoperatively in only five cases. This indicates that, although they are well documented, unicameral bone cysts of the pelvis remain a diagnostic problem. Patients received a spectrum of treatments from curettage to observation. There appeared to be no difference in the outcome after any form of treatment. Therefore, unicameral bone cysts of the pelvis can be managed conservatively. The choice to manage patients conservatively depends on making the correct diagnosis based on clinical history and imaging. The most effective imaging is a combination of plain radiographs, computed tomography (CT) and magnetic resonance imaging (MRI).
骨盆单房骨囊肿极为罕见。本研究总结了16例患者的临床、放射学及病理学特征。患者年龄从9岁至69岁不等。多数病变位于髂骨翼前部；许多病变似乎与髂嵴骨骺开口有关。这表明髂骨这一部位的单房骨囊肿发病机制与肱骨近端和股骨近端相似。仅5例患者术前做出了正确诊断。这表明，尽管骨盆单房骨囊肿已有充分文献记载，但仍是一个诊断难题。患者接受了从刮除术到观察等一系列治疗。任何形式的治疗后结果似乎并无差异。因此，骨盆单房骨囊肿可采用保守治疗。对患者进行保守治疗的选择取决于根据临床病史和影像学做出正确诊断。最有效的影像学检查是X线平片、计算机断层扫描（CT）和磁共振成像（MRI）相结合。
