Orbital Cysticercosis: Comparing Multi-Slice CT and Steady State MR to Identify Scolex.

Orbital cysticercosis with both ocular and extraocular involvement is common in endemic areas. The presence of scolex is considered diagnostic of cysticercosis. We sought to compare multi-slice CT and 3D steady state MR in the identification of scolex in orbital cysticercosis. Three patients with orbital cysticercosis (two extra-ocular, one ocular) were studied using multi-slice CT with thin coronal and sagittal reformations and 3D steady state MR (CISS 3D - Constructive Interference in Steady State) sequence.
