Frontal sinus osteoma accompanied by intracranial mucocele and local hyperostosis frontalis interna has never been reported. A 47-year-old woman presented with a 3-month history of intermittent headache. Physical examination revealed no neurologic abnormality. Contrasted magnetic resonance imaging showed a frontal heterogeneously enhanced lesion with adjacent nonenhanced cyst. Computed tomography showed a bone density mass, which was accompanied by local hyperostosis frontalis interna, which filled the left frontal sinus and extended intracranially. The patient underwent a left frontobasal craniotomy. Both the osseous mass and cyst capsule were removed totally via a frontal craniotomy, followed by skull base reconstruction. The postoperative course was uneventful. The final pathologic diagnosis was osteoma and mucocele.
伴有颅内黏液囊肿和局限性额骨内板增生的额窦骨瘤此前未见报道。一名47岁女性，有3个月间歇性头痛病史。体格检查未发现神经功能异常。增强磁共振成像显示额叶有一不均匀强化病灶，相邻有非强化囊肿。计算机断层扫描显示一骨质密度肿块，伴有局限性额骨内板增生，该肿块充满左侧额窦并向颅内延伸。患者接受了左额底开颅手术。通过额部开颅术将骨性肿块和囊肿包膜完全切除，随后进行颅底重建。术后过程顺利。最终病理诊断为骨瘤和黏液囊肿。
