Out of total 62 cases, acoustic schwannoma
accounted for the highest number of cases -42 cases (67.
Dosimetric comparison of Linac-based (BrainLAB) and robotic radio-surgery (CyberKnife) stereotactic system plans for acoustic schwannoma
Role of MRI in the evaluation of acoustic schwannoma
and its comparison to histopathological findings.
Cerebellopontine angle tumors correspond 8% of intracranial tumors, and acoustic schwannoma
is the most frequent, corresponding to 80-90% of the region, followed by meningioma (510%) and epidermoid (5%) (1,2).
Magnetic resonance imaging revealed a mass on the intracanalicular segment of cranial nerve VIII on the left side, consistent with acoustic schwannoma
A 55-year-old woman with acoustic schwannoma
was scheduled for craniotomy.
SRS was performed for acoustic schwannoma
either as first-time treatment or for residual tumor.
usually tend to show iso to hypodense CPA mass compared to brain in non-contrast CT and show strong enhancement following contrast administration.
PRESENTATION, DIAGNOSIS, MANAGEMENT: A 23years old G2P1L1 diagnosed with acoustic schwannoma
presented at 41 weeks of gestation and was posted for an emergency caesarean section along with V-P shunt placement.
Multiple neurofibromas are a distinctive feature of neurofibromatosis (NF) type 1 and bilateral acoustic Schwannomas
are a feature of NF type 2.
3) NF2 is mutated in sporadic schwannomas as well as in those occurring in patients with neurofibromatosis 2 who develop bilateral acoustic schwannomas
Primary extracranial meningiomas of the head and neck have also shown to have a relationship with neurofibromatosis, particularly type 2 NF characterized by bilateral acoustic schwannomas
and lack of skin findings and having a defect on chromosome 22q with an autosomal-dominant inheritance pattern .
