Very asymmetric disc edema in fulminant idiopathic intracranial hypertension: A rare and an unusual clinical finding

Fulminant idiopathic intracranial hypertension (IIH) can present as a rapid and severe vision-threatening condition, particularly in young females. We present a distinctive case of fulminant IIH characterized by asymmetrical vision loss with unilateral disc edema with loss of vision in the eye without disc edema. The patient exhibited an unusual serial sequence of radiological signs of raised intracranial pressure, emphasizing the need for emergent treatment. Resolution of the radiological signs was achieved following theco-peritoneal shunt placement. This case highlights the occurrence of fulminant IIH in unilateral disc edema and cause–effect relation between raised intracranial pressure and radiological signs and educative emphasis on the pathophysiology of the condition.
