Magnetic resonance imaging in pseudotumor cerebri: A case report

Abstract

Idiopathic intracranial hypertension (IIH) is characterized by symptoms of raised intracranial tension (ICT) as headache and visual disturbances due to raised cerebrospinal fluid pressure, however without any ventricular enlargement or space occupying lesion. The characteristic findings include papilledema which is usually bilateral, however which may be unilateral or asymmetrical. We report a case of 35-year-old female patient who came with complaints of headache and diplopia. She underwent magnetic resonance imaging of the brain which showed changes in bilateral globes, optic nerves and sella, which were suggestive of increased ICT. The ventricles and basal cisterns were normal. No other abnormality was seen. The magnetic resonance venogram was also normal. Thus, we concluded the diagnosis of IIH. The patient underwent therapeutic lumbar puncture after which she showed significant improvement in symptoms.
