Pseudomeningocele after Surgical Fenestration of A Posterior Fossa Arachnoid Cyst
We report a 7-year-old boy with a history of headaches, staring spells and speech delay. His neurological examination showed difficulties with tandem gait but no other cerebellar signs. Head CT showed an incidental mass suggestive of large arachnoid cyst of the posterior fossa. Brain MRI showed a cystic lesion at the inferomedial aspect of the left cerebellar hemisphere that follows CSF on all ...
متن کاملAseptic meningitis after posterior fossa surgery treated by pseudomeningocele closure.
Aseptic meningitis is a recognised complication after posterior fossa surgery. It is often self limiting but occasionally runs a protracted course requiring repeated CSF examination to exclude infection, and treatment with systemic steroids. A patient is described with aseptic meningitis after posterior fossa surgery who underwent posterior fossa re-exploration nearly 3 years after the initial ...
متن کاملElectrophysiological monitoring during acoustic neuroma and other posterior fossa surgery.
Techniques used to monitor the function of the seventh and eighth cranial nerves during acoustic neuroma and other posterior fossa surgery are reviewed. The auditory brainstem response (ABR), electrocochleogram (ECochG) and direct recording from the auditory nerve (CNAP) were compared. The best technique is the ECochG, although in many cases, the CNAP should be used as a back-up technique. The ...
متن کاملDense dermoid cyst of the posterior fossa.
A 54-year-old woman who had a history of chronic headache had atrophy of the right sternocleidomastoid muscle and ipsilateral strap muscles. CT showed a midline high-attenuation (364 H) mass 4 x 5 em in the posterior fossa (Fig. 1A). Vermian atrophy was seen with no mass effect or hydrocephalus. Angiography showed displacement of the vessels of the posterior fossa without tumor staining. MR sho...
متن کاملDermoid cyst of the posterior fossa.
Intracranial dermoid tumors represent a rare clinical entity accounting for 0.1-0.7% of all intracranial tumors. Their location in the posterior fossa is uncommon. We report a 16-year-old male patient who presented with clinical signs of increased intracranial pressure and cerebellar symptoms. The CT scan revealed a median cystic lesion of the fourth ventricle causing an active triventicular hy...
