Primary Middle Ear Meningioma: Case Report and Literature Review.

Primary middle ear meningiomas are exceptionally rare extracranial tumors, often misdiagnosed due to their nonspecific clinical and radiological features. Accurate diagnosis requires histopathological and immunohistochemical confirmation to distinguish them from common middle ear pathologies. We present a 59-year-old male patient with a 2-year history of intermittent right ear otorrhea and conductive hearing loss. Imaging revealed middle ear opacification with ossicular erosion, prompting surgical excision. Histopathology confirmed primary meningioma, and postoperative follow-up showed no recurrence. Literature review of relevant studies was conducted to summarize clinical and histopathological characteristics of primary middle ear meningioma.
