We studied the ex vivo production of prostaglandin D2, prostaglandin E2, 6-ketoprostaglandin F1 alpha, and leukotriene C4 in the brain tissue of rats subjected to experimental subarachnoid hemorrhage. The ex vivo method allows the study of arachidonic acid metabolites released from brain slices at different times after subarachnoid hemorrhage induction and reflects the residual capacity for ara...

This case report illustrates a patient who was found to have multiple sites of angioblastic meningiomas in the spinal and intracranial subarachnoid space 15 to 18 years after resection of an angioblastic meningioma from the upper cervical canal. The presence of the multiple sites of tumor could represent either multicentric origin or subarachnoid seeding.

The glymphatic system has in previous studies been shown as fundamental to clearance of waste metabolites from the brain interstitial space, and is proposed to be instrumental in normal ageing and brain pathology such as Alzheimer's disease and brain trauma. Assessment of glymphatic function using magnetic resonance imaging with intrathecal contrast agent as a cerebrospinal fluid tracer has so ...

Acromegaly usually presents in middle age with the gradual onset of classical signs and symptoms. We report the case of an elderly woman who presented with subarachnoid haemorrhage due to infarction of a pituitary adenoma and rupture into the subarachnoid space.

The effect of subarachnoid hemorrhage on metabolic rates in rabbit cerebral arteries was investigated by measuring adenosine triphosphate (ATP) content and L-lactate release. The mean +/- SEM ATP content was 0.38 +/- 0.02 mumol/g wet wt in control rabbit basilar arteries (n = 6). The ATP content decreased significantly to 0.17 +/- 0.02 mumol/g wet wt 2 days after experimental subarachnoid hemor...

ABSTRACT: Intracranial pressure (ICP) monitoring is considered the gold standard for optimizing treatment of humans in intensive care units. However, this procedure not commonly performed veterinary medicine because limitations and complications method. There are some new promising non-invasive techniques ICP, but they have been validated medicine. This study aimed to correlate intracranial (NI...

DISCUSSION Cerebrocirculatory arrest and reperfusion causes injury that breaks down the blood–brain barrier. In patients undergoing contrast imaging, there may be active extravasation of contrast into the subarachnoid space. Hypothermia alters contrast viscosity, decreases glomerular filtration, and subsequently decreases elimination of the contrast. It is important to recognize such mimickers ...
