pseudotumor

 [soo″do-too´mer]
an enlargement that resembles a tumor; it may result from inflammation, accumulation of fluid, or other causes, and may or may not regress spontaneously.
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

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.
4. Normal CSF Clinical Vision defects–loss of acuity, diplopia, blind spots, headaches, N&V, vertigo, tinnitus Etiology Anemia, leukemia, hyper- or hypovitaminosis A, lead intoxication, nalidixic acid, poliomyelitis, Guillain-Barre disease, menarche, pregnancy, galactokinase deficiency, hypoxia, allergies, cerebral trauma, steroid therapy for cerebral edema, withdrawal of steroids, chronic hypocalcemia with hypoparathyroidism with 1º adrenal insufficiency, thyroid replacement therapy, endocrinopathies–Addison's or Cushing's diseases, OCs, tetracycline–in infants, intracranial venous occlusion, inflammation.

(sū'dō-tū'mĕr ser'ĕ-brī)
A condition, commonly associated with obesity in young women, of cerebral edema with narrowed small ventricles but with increased intracranial pressure and frequently papilledema.
