Abstrakt: Parasinusal osteoma complicated by intracranial and orbit extension, cranial vault hyperostosis, intracranial mucocele, and inflammatory pseudotumor is exceptional. A 68-year-old man presented with a long history of progressive proptosis and recurrent episodes of keratoconjunctivitis in the left eye, with restriction in upward gaze. Contrast-enhanced magnetic resonance imaging revealed a frontal sinus lesion extending to the left anterior fossa and orbit, featuring an intracranial cystic component and heterogeneous contrast enhancement. Head computed tomography confirmed the double calcific-cystic nature of the lesion. A left supraorbital-pterional approach allowed complete resection of mucocele and drilling of intracranial and orbital osteoma, including the intrasinusal component. The frontal sinus was cranialized, and a flap of pericranium, reinforced by Gelfoam sponge, was reflected on the anterior cranial base/orbital roof. The postoperative course was uneventful; magnetic resonance imaging depicted resolution of proptosis. Histological examination favored parasinusal osteoma associated with intracranial mucocele, frontal bone hyperostosis, and inflammatory pseudotumor.
