Primary Intracranial Malignant Nerve Sheath Tumor in the Cerebellopontine Angle in a Woman with Neurofibromatosis Type 2
Neurofibromatosis type 2 is an inherited disease. 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. We report here a 20-year-old woman with primary intracranial malignant nerve sheath tumor located in the left cerebellopontine angle. Histologically, the tumor showed malignant spindle c...
متن کاملChronic granulomatous abscess simulating cerebellopontine angle tumor.
The delayed development of brain abscess associated with a retained intracranial foreign body is not rare and has been documented [1-5] . We report an unusual case of chronic granulomatous abscess in the cerebellopontine angle region secondary to retention of a cotton ball during surgery for an acoustic neurinoma 20 years earlier. We describe the computed tomographic (CT) findings and emphasize...

Previously named as aggressive papillary middle ear tumors, they have recently been shown to arise from the endolymphatic sac. They are a rare in cerebello-pontine angle (CPA). We present a case of an ELST who presented as a CPA tumor with hydrocephalus. He underwent a ventriculo-peritoneal shunt initially. On explo...
متن کاملA rare case of malignant triton tumor in the cerebellopontine angle
UNLABELLED Malignant triton tumor (MTT) is defined as malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation. Intracranial MTT is extremely rare, and only four cases have been reported in the literature. Here, we report a case of MTT occurring in the cerebellopontine angle, and describe its histopathological characteristics, immunohistochemical features, and prognosis. ...
متن کاملMalignant Transformation of an Epidermoid Cyst in the Cerebellopontine Angle
Intracranial squamous cell carcinoma is extremely rare, with most of the cases arising from malignant transformation of an epidermoid or a dermoid cyst. The patient presented with facial weakness.
