Paranasal sinus Osteoma with Mucocele: A case report and literature review

Background: Osteoma associated with Mucocele remains an extremely rare occurrence. Case description: A 49-year-old female with high blood pressure, under medical treatment. She presented a 7-month history of right periorbital swelling with ptosis followed by intermittent headaches and dizziness. Brain imaging revealed a right ethmoido-front-orbital bone lesion, heterogeneous condensing, and polycyclic contours, surrounded by a fluid collection with hyperdense walls. A right frontal craniotomy was retained. Both tumors, Osteoma and Mucocele were excised and confirmed by histology. A depletive lumbar puncture was done to prevent any increase in intracranial pressure. Conclusion: Osteoma and Mucocele are rare benign brain tumors. The combination of both remains rare. Early diagnosis and treatment of Osteomas might prevent surges of multiple complications, the most notable one being Mucocele.
