BENIGN INTRACRANIAL HYPERTENSION (BIH) -PSEUDOTUMOR CEREBRI-

AT HIGH RISK ?!

DEFINITION

It is a syndrome that is defined by five criteria:
1-Increased intracranial pressure
2-Normal or small sized ventricles by neuroimaging
3-No evidence of an intracranial mass
4-Normal CSF composition
5-Papilledema

CLINICAL PRESENTATION OF BIH

DIAGNOSIS

CT-SCAN OF BIH (NORMAL CT)

TREATMENT

1- STEROIDS
2- ANALGESIA
3- DIURETICS
