Pneumocephalus associated with a frontoethmoidal osteoma.

W A Jackson, K A Bell

    The Journal of the Louisiana State Medical Society : Official Organ of the Louisiana State Medical Society
    |December 1, 1989
    PubMed
    Summary

    A persistent headache in a 51-year-old man was caused by pneumocephalus, a condition of air in the skull. This was due to a sinus osteoma, a benign bone tumor, compressing the brain.

    Area of Science:

    • Neurosurgery
    • Otolaryngology
    • Radiology

    Background:

    • Headaches can be caused by various intracranial and extracranial pathologies.
    • Pneumocephalus, the presence of air within the cranial cavity, is a rare but serious condition.
    • Sinonasal osteomas are benign tumors that can cause local complications.

    Observation:

    • A 51-year-old male presented with a two-month history of headache.
    • Computed tomography (CT) revealed pneumocephalus and an osteoma at the confluence of the frontal and ethmoid sinuses.
    • The osteoma exhibited a spur-like projection.

    Findings:

    • Surgical exploration via craniotomy confirmed the presence of a sphenoid sinus osteoma.
    • The osteoma's spur was identified as the direct cause of the pneumocephalus.
    • The patient's symptoms resolved following surgical resection of the osteoma.

    Implications:

    • This case highlights the importance of considering sinonasal tumors in the differential diagnosis of persistent headaches with pneumocephalus.
    • Early diagnosis and surgical intervention are crucial for managing osteoma-induced complications.
    • Understanding the anatomical relationship between sinonasal structures and the cranial cavity is vital for neurosurgeons and otolaryngologists.
