pseudotumor

 [soo″do-too´mer]

pseudotumor ce´rebri cerebral edema and raised intracranial pressure without neurological signs except occasional sixth-nerve palsy.
inflammatory pseudotumor a tumorlike mass resulting from an inflammatory reaction; it may occur in a variety of organs and is composed of granulation tissue with leukocyte infiltration.

pseu·do·tu·mor ce·re·bri

a disorder most commonly seen in obese young women, characterized clinically by headache, blurred vision, and visual obscurations resulting from increased intracranial hypertension; on clinical examination, papilledema is detected but on neuroimaging studies there is no evidence of an intracranial mass lesion and the ventricles are either of normal size or small; if untreated, occasionally results in permanent visual loss; of an unknown cause.

pseudotumor cerebri

a condition characterized by increased intracranial pressure, headache, blurring of the optic disc margins, vomiting, and papilledema without neurological signs, except palsy of the sixth cranial nerve. Also called benign intracranial hypertension, meningeal hydrops.

pseudotumor cerebri

Benign intracranial hypertension, Neurology A condition caused by ↑ intracranial pressure with normal CSF; PC is most common in young obese ♀ with dysmenorrhea of ovarian origin, and is diagnosed by
1. Presence of bilateral papilledema and objective evidence of ↑ intracranial pressure.
2. Absence of focal neurological Sx or signs.
3. Absence of an extracranial cause of papilledema.
