Two Cases of Vestibular Nerve Hybrid Nerve Sheath Tumors and Literature Review.

The article discusses two cases of vestibular nerve hybrid nerve sheath tumors at a tertiary care referral center, which were initially presumed to be vestibular Schwannomas. The cases were diagnosed as hybrid tumors upon pathological analysis. A literature review revealed a limited number of reported cases of hybrid tumors affecting cranial nerves, indicating that such tumors may be underreported in the cranial region. The study highlights the importance of recognizing hybrid nerve sheath tumors as a distinct entity in the classification of central nervous system tumors. [Extracted from the article]
