ABSTRACT A 19‐year‐old woman presented with headache and visual impairment. Lumbar puncture revealed markedly elevated intracranial pressure, while magnetic resonance imaging showed no evidence of cerebral venous sinus thrombosis, suggesting idiopathic intracranial hypertension. On Day 5, however, computed tomography angiography identified thrombi extending from the right transverse sinus to the superior sagittal sinus. Anticoagulant treatment and thrombus retrieval successfully resolved the thrombi, but elevated intracranial pressure persisted until subsequent lumbar–peritoneal shunt placement. This case represents a rare instance wherein idiopathic intracranial hypertension may have precipitated cerebral venous sinus thrombosis.
