Pilocytic astrocytoma sometimes transforms to a malignant type, and previous radiation therapy is considered to be a key factor. We report a case of pilocytic astrocytoma with histological malignant features without previous radiation therapy. A 21-year-old man presented a sudden onset of severe headache. Neuroimaging had detected a cystic mass in the posterior fossa at the age of one year with...

Malignant hypertension develops in some cases of hypertension but not in others. We hypothesized that an impaired neovascularization and a reduced capillary supply characterizes the malignant course of experimental hypertension. Two-kidney, one-clip renovascular hypertension was induced in rats; controls (sham) were sham operated. To distinguish malignant hypertension from non-malignant hyperte...
conclusions small size, smooth lesion border and homogeneity favor benign nature of the incidental splenic lesions, while restricted diffusion might be a feature of malignancy. follow-up imaging might be helpful in a subset of patients to discriminate benign and malignant incidental splenic lesions. methods this retrospective study was performed in a tertiary referral center. data of patients w...
BACKGROUND AND PURPOSE Early predictors of infarct volume may improve therapeutic decisions in patients with acute cerebral ischemia. We investigated whether measurements of serum astroglial protein S100B can predict a malignant course of infarction in acute middle cerebral artery (MCA) occlusion. METHODS We included 51 patients (24 women, mean age 69.1+/-12.4 years) admitted within 6 hours a...
BACKGROUND AND PURPOSE To predict malignant course in patients with large middle cerebral artery (MCA) infarction, we combined PET imaging and neuromonitoring, including microdialysis. METHODS Thirty-four patients with stroke of >50% of the MCA territory in early cerebral CT scan were included. Probes for microdialysis and measurement of intracranial pressure and tissue oxygen pressure (Pto2)...
