The formation of symptomatic intradural mucocele associated with a paranasal osteoma is rare, and no standard treatment has been established. Here, we present a case of intradural mucocele in a 27-year-old man complaining of headache and generalized convulsion. Cranial CT and brain MRI showed a left frontoethmoidal osteoma extending into the left anterior cranial fossa and orbit along with a mass in the left frontal lobe. He underwent resection of both intracranial osteomas and the mass through left frontal craniotomy. Histological findings were consistent with a mucocele, and the diagnosis of an intradural mucocele associated with a frontoethmoidal osteoma was confirmed. The postoperative course was uneventful. Although both osteoma and mucocele are benign, they may cause life-threatening symptoms by expanding intracranially. A tailored treatment considering the invasiveness and postoperative long-term follow-up of the patient is essential for this uncommon condition.
伴有鼻旁骨瘤的症状性硬膜内黏液囊肿的形成较为罕见，目前尚未确立标准治疗方法。在此，我们报告一例27岁男性硬膜内黏液囊肿病例，该患者主诉头痛和全身性惊厥。头颅CT和脑部MRI显示，左侧额筛骨瘤沿左侧前颅窝和眼眶延伸，并伴有左侧额叶肿块。他通过左额开颅手术切除了颅内骨瘤和肿块。组织学检查结果与黏液囊肿相符，确诊为伴有额筛骨瘤的硬膜内黏液囊肿。术后病程平稳。尽管骨瘤和黏液囊肿均为良性，但它们可能因颅内扩张而导致危及生命的症状。对于这种罕见疾病，考虑到患者的侵袭性和术后长期随访进行个性化治疗至关重要。
