Diagnosis: Middle ear hemangioma
Hemangiomas are lesions that rarely involve the middle ear and mimic clinical and radiologic features of other more common vascular tumors. They are considered to be extraneural lesions, which most commonly occur in the temporal bone at the geniculate ganglion followed by the internal auditory canal (especially near the fundus) and the mastoid at the origin of the chorda tympani nerve.1 Most lesions are thought to develop from the capillary plexus surrounding the Scarpa ganglion; therefore, sensorineural hearing loss is often the initial symptom.
