Sub-occipital or posterior fossa
craniotomy: Bone is removed from the back of the base of the skull in order to relieve pressure and to create more room for the cerebellum and brain stem.
My youngest son, Hudson, was diagnosed with a fast-growing, posterior fossa
, atypical teratoid rhabdoid tumor (ATRT) of the brain.
A posterior fossa
haematoma and further neurological deterioration complicated external ventricular drainage presumably due to sudden intracranial hypotension.
Considering the fact, that the upper anterior third of the posterior fossa
is surgically hidden, the narrow passage between the petroclival surface anteriorly and the surface of the brainstem posteriorly may be essential for any surgical approach to the basilar region (2).
Emergency posterior fossa
craniectomy and foramen magnum decompression were performed.
He and his colleagues reviewed the records of 46 patients aged 17 years and older who underwent posterior fossa
MRA between 2000 and 2003.
There may also be descent of the cerebellar tonsils, obliteration of prepontine, perichiasmatic cisterns, flattening of the optic chiasm, crowding of the posterior fossa
, as well as decreased ventricular size, according to Dr.
A posterior fossa
craniotomy revealed a solid, reddish fleshy lesion in the cerebellar vermis that blended in with the surrounding cerebellum.
In 1987, a 57-year-old woman was hospitalized for gait ataxia, dysarthria, dizziness, and bilateral hypertonus 43 months following a posterior fossa
decompression and cervical vertebrae level 1 laminectomy, which included placement of a LYODURA[R] graft to correct an Arnold-Chiari malformation and syringomyelia.
In June 1985, BC/BS updated its assessment and recommended that MRI be considered" generally accepted medical practice for diagnostic conditions of the posterior fossa
(cerebellum and brainstem) and high (C1 through C4) cervical cord and demyelinating diseases of the white matter of the brain.
This comprehensive reference text on cerebellar disorders in children includes chapters on cerebellar development, prenatal cerebellar imaging, imaging of the posterior fossa
, with coverage of a broad range of malformations, genetic and metabolic disorders involving the cerebellum, prenatal cerebellar disruptions (as related to prematurity), vascular disorders, tumors and paraneoplastic syndromes, as well as acute ataxia and trauma to the posterior fossa
