1) More than 30% of intracranial neoplastic diseases are caused by metastases/secondaries
(breast, lung, melanoma). Primaries
include: astocytomas, glioblastoma multiforme, oligodendrogliomas, ependymomas,
meningiomas. 2) Rising intracranial pressure can be caused by e. g. head injury,
meningoencephalitis, haemorrhage or cerebral oedema and tumour
D:
(CCT
after contrast) At brain windows there are multiple, rounded, enhancing soft-tissue
masses, some with surrounding oedema (low density areas), throughout both hemispheres
and especially throughout the cerebellum. As evidence of rising intracranial
pressure the sulci are flattened against the inner skull. Hence evidence of
multiple metastases from malignant melanoma.
