The effects of arterial hypotension and a raised intracranial pressure on cerebral blood flow (CBF) have been investigated in an animal model of hepatic failure. Arterial hypotension was associated with a fall in CBF in the animals with liver failure but not in the controls. Significant differences in mean CBF between the two groups of animals could be demonstrated when the systolic blood press...

Head injury is a common form of trauma. For example, in the UK head injury occurs in more than 500 000 persons per annum of which about 10% are diagnosed as severe, 15% moderate and the remainder as minor head injury (Miller et al., 1992; Pickard and Czosnyka, 1993). Head trauma is a significant cause of death and disability, especially in young males (median age < 30) and is associated with ra...

Chronic fatigue syndrome and cases of idiopathic intracranial hypertension without signs of raised intracranial pressure can be impossible to distinguish without direct measurement of intracranial pressure. Moreover, lumbar puncture, the usual method of measuring intracranial pressure, can produce a similar respite from symptoms in patients with chronic fatigue as it does in idiopathic intracra...

A 28-year-old man presented with history of raised intracranial pressure and one episode of generalized tonic clonic seizures. Computed Tomogram revealed multiple contrast enhancing intracranial lesions. Biopsy of one of the lesions was reported as metastatic alveolar soft part sarcoma. He was advised whole brain radiotherapy.

Two cases of primary intracranial choriocarcinoma are reported. One patient died with raised intracranial pressure and pulmonary metastases whereas the second patient, who was diagnosed early, has remained well a year after chemotherapy. Human chorionic gonadotrophin level estimation in serum and cerebrospinal fluid is a useful marker in suspected cases, and chemotherapy following biopsy appear...

Two patients with meningoradiculitis associated with HIV presented with symptoms and signs of intracranial hypertension. In the patients described, the raised intracranial pressure resolved after lumbar puncture. After exclusion of opportunistic infection, such patients may be managed with therapeutic lumbar puncture alone.

Intracranial schwannoma not related to cranial nerves are unusual and rarely found in the subfrontal region. We report a case of cystic olfactory groove schwannoma in a 55-year- old male, who presented with late onset seizure without raised intracranial pressure. The tumor was excised completely.

human infection with echinococcus granulosis is a common disease throughout south america, the mediterranean littoral, the middle east, central asia and east africa, which usually occur in children and young adults. formation of avascular cystic lesions in the liver, kidney, pancreas, bones, vitreus and brain can cause protean of signs and symptoms. intracranial cysts usually present with focal...
