Giant intraparenchymal neurocysticercosis: unusual MRI findings.

ABSTRACT

We report a case of surgically proven giant neurocysticercosis (NCC). MR imaging revealed an unusually large solitary parenchymal cystic lesion showing signal intensity similar to CSF on all pulse sequences, with internal septations and a small nodule in the anterior aspect of this lesion compatible with this diagnosis. Identification of a scolex in a cystic lesion with CSF intensity plays a key role in the diagnosis of NCC. The presence of internal septations is an atypical feature.
