Abstract

Primary hydatid cysts typically occur in the lungs or the liver, but can be found elsewhere without involving these organs. Primary bone cysts are rare and frequently missed. No standard treatment exists, especially for inoperable patients. A 53-year-old female patient with pain and swelling in the left gluteal region for a month was first admitted 3 years ago, with an initial diagnosis of DVT. Incidentally, magnetic resonance imaging showed cystic involvement of the pelvis, and an iliac bone biopsy suggested a diagnosis of hydatidosis. The cyst was inoperable, and praziquantel and albendazole chemotherapy was initiated. The patient was followed after 3 years, having a palpable 12 × 9 cm mass and showing minor radiographic changes. We report an unusual and inoperable case of primary bone hydatid cyst, with involvement of pelvic bones and surrounding soft tissue. This case suggests that cystic mass, especially where disease is endemic, should raise suspicion of echinococcosis. The chemotherapy regimen appears to have limited the growth of the cysts.

臀骨受累无法手术的骨盆骨原发性Hy虫病：罕见表现和随访的诊断

摘要

原发的包虫囊肿通常发生在肺部或肝脏中，但可以在其他地方发现而没有涉及这些器官。原发性骨囊肿很少见，经常遗漏。没有标准的治疗方法，特别是对于不能手术的患者。一位53岁的女性患者在3月前首次入院，该患者在左臀区疼痛和肿胀，持续了一个月，最初诊断为DVT。顺便说一句，磁共振成像显示骨盆囊性受累，an骨活检提示诊断为包虫。囊肿无法手术，并开始吡喹酮和阿苯达唑化疗。3年后随访患者，可触知的肿块为12×9 cm，并且影像学上有轻微变化。我们报告了原发性骨包虫囊肿的一种罕见且无法手术的病例，伴有骨盆骨头和周围的软组织。该病例表明，囊性肿块，尤其是疾病为地方性囊肿，应引起对棘球菌病的怀疑。化疗方案似乎限制了囊肿的生长。
