Giant frontal sinus mucocele mimicked a primary brain tumor: A case report

Introduction: Frontal sinus mucoceles commonly manifest with orbital complications. Intracranial complications, though rare, are significant in the differential diagnosis. Tumefactive and giant mucoceles can resemble intracranial tumors. Case presentation: We present the case of a 24 -year -old male patient who initially presented to our institution after experiencing a single generalized tonic-clonic seizure. Initial imaging revealed large masses in both frontal lobes. Surgical intervention revealed mucoceles originating from the frontal and paranasal sinuses. Discussion: Mucoceles are often misdiagnosed due to the wide variety of symptoms they can present. In particular, the tumefactive type of mucoceles can present brain tumors both clinically and radiologically. Conclusion: Mucoceles can manifest as tumefactive lesions, mimicking intracranial masses, and may present as perplexing neurological conditions.
