Although there are numerous aetiologies for coccygodynia described in the medical literature, precoccygeal epidermal inclusion cyst presenting as a coccygodynia has not been reported. We report a 30-year-old woman with intractable coccygodynia. Magnetic resonance imaging showed a circumscribed precoccygeal cystic lesion. The removed cyst was pearly-white in appearance and contained cheesy material. Histological evaluation established the diagnosis of epidermal inclusion cyst with mild nonspecific inflammation. The patient became asymptomatic and remained so at two years follow-up. This report suggests that precoccygeal epidermal inclusion cyst should be considered as one of the differential diagnosis of coccygodynia. Our experience suggests that patients with intractable coccygodynia should have a magnetic resonance imaging to rule out treatable causes of coccygodynia.
尽管医学文献中描述了尾骨痛的多种病因，但以尾骨痛形式出现的尾骨前表皮样囊肿尚未见报道。我们报告一名30岁患有顽固性尾骨痛的女性。磁共振成像显示尾骨前有一个边界清晰的囊性病变。切除的囊肿外观呈珍珠白色，内含干酪样物质。组织学评估确诊为表皮样囊肿伴轻度非特异性炎症。患者症状消失，在两年随访中一直保持无症状。本报告提示，尾骨前表皮样囊肿应被视为尾骨痛的鉴别诊断之一。我们的经验表明，患有顽固性尾骨痛的患者应进行磁共振成像检查，以排除可治疗的尾骨痛病因。
