RESUMO
Acoustic neuromas are the most common lesion in the cerebellopontine angle. The authors report a unique case of acoustic schwannoma, presenting in middle cranial fossa masquerading as meningioma in a 24-year-old man, presenting with headache and focal seizures. Contrast-enhanced MRI of the brain revealed a mass lesion of the right middle cranial fossa consistent with features of meningioma.Intraoperatively a well-defined tumor with attachment to anterior petrous bone was excised. In the immediate postoperative period, the patient developed right-sided hearing loss, which was proven to be retrochoclear hearing loss on brainstem evoked response audiometry. Histopathology findings were consistent with benign schwannoma. Acoustic schwannoma originating in an unusual location middle cranial fossa is a plausible explanation of such unusual occurrence. Such a case has never been reported in the literature.
RESUMO
Spinal paragangliomas are neuroendocrine tumours of the extra adrenal paraganglionic system. These tumours are very rare. A case of spinal paraganglioma in an elderly male is reported. A 54-year-old male reported with low backache. Magnetic resonance imaging lumbosacral spine revealed an enhancing intradural lesion at L3 level for which he was operated and histopathology revealed it to be a paraganglioma. Spinal paragangliomas are benign neoplasms and need to be distinguished from more aggressive tumours as their prognosis is excellent
