High systolic blood pressure, high pulse pressure, and hypertension were associated with new deep or infratentorial
microbleeds but not with new lobar microbleeds.
Cerebral MRI, performed 24 hours later, showed features of encephalitis with diffuse white matter signal abnormalities in the supratentorial and infratentorial
Medulloblastoma is the most common malignant brain tumor of childhood, causing 33% of all infratentorial
tumors in children.
For patients with evidence of intracranial metastatic prostate cancer average survival is one month without and three and a half months with treatment and the histology or the location of the lesion supra or infratentorial
did not alter the survival rate.
A final model that included Gd-enhancement, juxtacortical, infratentorial
and periventricular lesions had an accuracy of 80%.
Differential growth between the fetal brain and its infratentorial
(11) Involvement of brainstem white matter has been found to extend from the internal capsules to the level of the pons, (17) medulla, (20) and cerebellar white matter, (20) though infratentorial
involvement is regarded as secondary to the primary abnormalities of the supratentorial white matter.
(especially cerebellar) lesions are also seen .
Types of brain tumors included medulloblastomas, infratentorial
glioma, and optic nerve meningioma, supratentorial glioma, and supratentorial choroids plexus papilloma.
Sudden decompression of the ventricles in the supratentorial compartment may have caused disruption of the bridging veins in the infratentorial
compartment, leading to formation of posterior fossa haematoma.
(9) Typically found in the infratentorial
region in children, ependymomas tend to be located in the supratentorial region in young adults.
