PURPOSE
Coccydynia is a common entity in orthopedic practice, and various etiologies have been described for it. However, benign dermoid cyst causing coccydynia has not yet been reported.
METHODS
A 20-year-old male presented with typical symptoms of coccydynia recalcitrant to conservative treatment for 2 years. Since pain interfered with his daily activities, magnetic resonance imaging was performed which showed a circumscribed precoccygeal cystic lesion.
RESULTS
The patient underwent coccygectomy along with cyst excision. Histological examination revealed features of benign dermoid cyst. After surgery, the patient had excellent relief of his symptoms.
CONCLUSION
The case report identifies that the treating surgeon should be aware of benign dermoid cyst as one of the treatable but rare causes of intractable coccydynia, and MRI should be performed in patients with persistent coccygeal pain.
目的
尾骨痛在骨科临床中较为常见，其病因多样。然而，由良性皮样囊肿引起的尾骨痛尚未见报道。
方法
一名20岁男性，有典型的尾骨痛症状，经保守治疗2年无效。因疼痛影响日常活动，遂行磁共振成像检查，结果显示尾骨前有一界限清楚的囊性病变。
结果
患者接受了尾骨切除术及囊肿切除术。组织学检查显示为良性皮样囊肿。术后患者症状得到显著缓解。
结论
该病例报告提示，治疗医生应意识到良性皮样囊肿是顽固性尾骨痛的可治疗但罕见的病因之一，对于持续存在尾骨疼痛的患者应行磁共振成像检查。
