متن کاملCerebellopontine angle primitive neuroectodermal tumor mimicking trigeminal schwannoma
BACKGROUND Primitive neuroectodermal tumors (PNETs) comprise a group of aggressive, poorly differentiated embryonal tumors occurring in central nervous system as well as in peripheral locations. Primary cerebellopontine angle (CPA) PNET is an extremely rare entity. It is important to have knowledge of this pathology and to be able to differentiate it from other commonly occurring CPA tumors, su...
متن کاملPrimary Intracranial Malignant Nerve Sheath Tumor in the Cerebellopontine Angle in a Woman with Neurofibromatosis Type 2

The main manifestation of the disease is the development of symmetric, non-malignant brain tumors in the region of the cranial nerve VIII usually as schwannoma.
