Cerebral venous sinus thrombosis in a child with Idiopathic nephrotic syndrome

Cerebral venous sinus thrombosis (CVST) is an uncommon complication of Nephrotic syndrome (NS). CVST occurring in a child with steroid sensitive nephrotic syndrome is described in this article. He presented initially with non specific symptoms of headache, lethargy and intermittent vomiting after 4 weeks of initiating steroid therapy. These were initially attributed to steroid therapy. Initial CT brain and MRI of the brain were normal. He developed intermittent convergent squint. At this time CVST was strongly suspected and MR angiography and MR venography was done which confirmed the CVST. Anticoagulation therapy was initiated with heparin and after three weeks changed to oral warfarin. He made slow but complete neurological and radiological recovery.
