Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
A brain tumor is an abnormal growth of cells within the brain or inside the skull, and can be cancerous or non-cancerous ().Just over half of all primary brain tumors are malignant; the rest are benign, though they may still be life-threatening.
The downside of using CT scans as opposed to MRI is that some brain tumors do not show up well on CT scans because some intra-axial masses are faint and resemble normal brain tissue. In some scenarios, brain tumors in CT scans may be mistaken for infarction, infection, and demyelination.
Cerebral edema is excess accumulation of fluid in the intracellular or extracellular spaces of the brain. [1] This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1]
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.

Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult.
At his graduation from a program in Michigan that lasted 45 days called A Forever Recovery, Quenton told her he was worried about leaving. “I don’t know, Mom. I’m safe here,” Ann recalled him saying. “I said, ‘Quenton, you don’t have to go home.’ He said, ‘No, Mom, it’s time to start my life.
