Conventional and diffusion-weighted magnetic resonance imaging findings in a pediatric patient with a posterior fossa brain tumor and papilledema.
We present a case report of a 21-month-old female patient to highlight magnetic resonance (MR) imaging findings associated with papilledema in a pediatric patient with an intracranial tumor. The MR findings included optic disc elevation, dilated perioptic subarachnoid spaces, optic nerve tortuosity and restricted diffusion in the optic nerve heads, all of which resolved upon resolution of raised intracranial pressure (ICP) and papilledema. The case demonstrates that both conventional and diffusion-weighted MR imaging findings can detect the presence, and follow posttreatment resolution, of increased ICP and papilledema in a pediatric tumor patient. The postoperative resolution of optic disc elevation clearly indicates the intracranial tumor etiology.
