Is a negative cranial CT-scan adequate to support a diagnosis of pseudotumor cerebri

Pseudotumor cerebri: a review.

Pseudotumor cerebri (PTC) is a syndrome seen more frequently in young, obese women defined by increased intracranial pressure without obstruction of the ventricular system. Normal neurodiagnostic studies, normal cerebrospinal fluid (CSF) contents, papilledema in one or both eyes, and normal mental status should also be recognized. Although the disorder has been associated with drugs, endocrinop...

Cranial venous outflow obstruction and pseudotumor Cerebri syndrome.

The pathophysiology of PTS including idiopathic intracranial hypertension or 'BIH', remains controversial. The older literature frequently referred to pathology in the cerebral venous drainage but more modern imaging techniques (CT and early MR) failed to reveal gross venous pathology. The role of impaired cranial venous outflow has recently been re-examined in the light of new methods of inves...

A cytology negative rare tumor with the presentation of pseudotumor cerebri clinical symptoms: diffuse leptomeningeal glioneuronal tumor

Diffuse leptomeningeal glioneuronal tumor is characterized by hydrocephalus, leptomeningeal involvement in the absence of a primary parenchymal mass, and negative cerebrospinal fluid (CSF) cytology. It is an extremely rare and difficult tumor to diagnose as no mass can be biopsied and it mimics infectious, rheumatologic, and inflammatory pathologies. An 11-year-old girl presented with complaint...

A Presentation of Lyme Disease: Pseudotumor Cerebri.

Lyme disease is caused by a tick-transmitted spirochete, B. burgdorferi. It can present with both central and peripheral nervous system manifestations, including aseptic meningitis, meningoencephalitis, Bell's palsy and other cranial neuropathies, radiculoneuritis, and myelitis. However, pseudotumor cerebri associated with Lyme disease is rare. Here, we report a eight-year-old girl with the unu...
