Osteoma of the Internal Auditory Canal as a Rare Finding in Imaging: A Case Report

Osteomas are a type of benign tumors that can develop in various bones of the skull. The fronto-ethmoidal region is the most commonly affected site, with over 50% of cases being reported in this location. The temporal bone, particularly the mastoid and external auditory canal regions, is another frequent site of osteoma formation. However, the occurrence of osteomas within the middle ear is relatively uncommon. The presence of osteomas within the internal auditory canal is a rare phenomenon and has been reported infrequently in the medical literature.

OSTEOMA OF THE FRONTAL SINUS

The occurrence of osteoma of the frontal sinus is relatively infrequent, as may be judged from the fact that Sewall, 1 after carefully reviewing the literature, found only ninety-two cases. In these cases the diagnosis was based on the presence of anatomic deformities secondary to the osteoma; in only a few had the roentgen ray been used to confirm the clinical impression, and in none had the condition been primarily diagnosed roentgenographically. During the past six months the following two cases of clinically unsuspected osteoma of the frontal sinus have been discovered in the routine examination of skull plates. Case 1. —A man entered the Stanford University Medical School Hospital, complaining of very severe headaches of long duration. In the early stages these had been frontal, but of late they had been principally occipital. Diffuse brain tumor seemed to be the clinical diagnosis. However, lateral stereoscopic skull plates showed an
