Neurothekeoma of petrous apex: A rare entity

Intraosseous nerve sheath tumors are very rare tumors accounting for lesser than 0.2% of primary bone tumors. We present an 18-year-old female who presented with left facial paresis for the last 1 year. Magnetic resonance imaging (MRI) demonstrated expansile, multiseptated, enhancing bony lesion in...

Description
Summary:Intraosseous nerve sheath tumors are very rare tumors accounting for lesser than 0.2% of primary bone tumors. We present an 18-year-old female who presented with left facial paresis for the last 1 year. Magnetic resonance imaging (MRI) demonstrated expansile, multiseptated, enhancing bony lesion in the left petrous apex. There was also abnormal enhancement of the 7-8th nerve complex within the internal auditory canal. Tumor was excised by subtemporal extradural approach. The lesion was diagnosed as intraosseous neurothekeoma on histopathology. This is an extremely rare tumor and its MRI appearance in this location is being described for the first time in literature.
