CT and MRI in a girl with late-onset ornithine transcarbamylase deficiency: case report

Abstract

We report CT and MRI findings in a girl with late-onset ornithine transcarbamylase deficiency, who presented with progressive somnolence. Both imaging methods showed signs of an acute cerebral ischaemia with new defects on follow-up. Despite an unusual clinical presentation, laboratory studies led to the diagnosis of this rare inherited metabolic defect.
