Frontal Sinus Osteoma Presenting with Meningitis and Epilepsy

Area of Science:

• Neurosurgery
• Otolaryngology
• Neurology

Background:

• Osteomas are benign bone tumors, commonly found in paranasal sinuses.
• Typically asymptomatic, large osteomas can lead to serious complications.

Observation:

• A 38-year-old man presented with chronic headache and worsening seizures.
• A large frontal sinus osteoma with intracranial extension was diagnosed.
• The patient had a history of meningitis.

Findings:

• This is the fourth reported case of frontal sinus osteoma associated with meningitis.
• Surgical resection of the osteoma was performed by a joint neurosurgery and otolaryngology team.
• The patient's seizures and headache resolved post-surgery.

Implications:

• Large or complicated sinus osteomas require a multidisciplinary approach for effective management.
• Early diagnosis and intervention are crucial for preventing severe neurological complications.
• This case underscores the importance of considering rare differentials in patients with refractory neurological symptoms.
