Bursae or abscess cavities communicating with the hip joint were demonstrated by hip arthrography or by computed tomography (CT) in 40 cases. The bursae or abscess cavities were associated with underlying abnormalities in the hip, including painful hip prostheses, infection, and inflammatory or degenerative arthritis. Structures communicating with the joint capsule included iliopsoas bursae (13 cases), bursae associated with the greater trochanter (21 cases), ischiotrochanteric bursae created by abnormal articulation between the ischium and lesser trochanter (two cases), and abscess cavities not associated with a bursa (four cases). Symptoms may be produced directly as a result of infection or indirectly as a result of inflammation or pressure on adjacent structures. In cases of suspected infection, direct puncture and aspiration of the bursa or abscess cavity, in addition to joint aspiration, may be necessary to obtain organisms for culture as joint aspiration may not yield fluid. Hip arthrography can confirm a diagnosis of bursae and abscess cavities communicating with the hip joint in patients with hip pain or soft-tissue masses around the groin. Differentiation of enlarged bursae from other abnormalities is important to avoid unnecessary or incorrect surgery.
40例患者通过髋关节造影或计算机断层扫描（CT）证实存在与髋关节相通的滑囊或脓肿腔。这些滑囊或脓肿腔与髋关节潜在异常相关，包括疼痛的髋关节假体、感染以及炎性或退行性关节炎。与关节囊相通的结构包括髂腰肌滑囊（13例）、与大转子相关的滑囊（21例）、坐骨与小转子间异常关节形成的坐骨转子滑囊（2例）以及与滑囊无关的脓肿腔（4例）。症状可能由感染直接引起，也可能由炎症或对相邻结构的压迫间接导致。在疑似感染的病例中，除了关节穿刺抽吸外，直接穿刺抽吸滑囊或脓肿腔可能是必要的，以便获取用于培养的微生物，因为关节穿刺抽吸可能无法获取液体。髋关节造影可确诊髋关节疼痛或腹股沟周围软组织肿块患者中与髋关节相通的滑囊和脓肿腔。区分肿大的滑囊与其他异常对于避免不必要或错误的手术很重要。
