ASSOCIATION OF PRIMARY INTRACRANIAL MENINGIOMA AND CUTANEOUS MENINGIOMA OF EXTERNAL AUDITORY-CANAL - A CASE-REPORT AND REVIEW OF THE LITERATURE

A cutaneous meningioma of the external auditory canal occurred in a 48 -year-old Filipino woman who had undergone subtotal resection of a dur al-based intracranial meningioma at the ipsilateral cerebellopontine a ngle 36 months previously. Radiologic findings demonstrated a recurren ce of intracranial meningioma with surface erosion and heterogeneous d ensities of the mastoid bone, without extension to the area of the ext ernal auditory canal. Meningioma in the external ear canal is extremel y rare. To our knowledge, there have been only two previously reported cases, both without intracranial lesion. In this case, the auditory c anal lesion may represent either an ectopic meningioma arising from an arachnoid cell rest or an occult direct extension from intracranial m enigioma.
