Axial T2WI and postcontrast T1WI at the level of the lateral ventricles demonstrate a well-delineated, thin-walled, non-enhancing cystic lesion with an eccentric mural nodule in the right-sided lateral ventricle (arrows), causing outflow obstruction through the ipsilateral interventricular foramen of Monro.

Therefore, we scheduled the patient for urgent MR imaging, which revealed a well-delineated, thin-walled, non-enhancing cystic lesion with an eccentric mural nodule in the right-sided lateral ventricle, causing outflow obstruction through the ipsilateral interventricular foramen of Monro (Fig. 1).
Histopathological images of the excised lesion demonstrate a nonviable, necrotic scolex projecting from the interior surface of a viable cystic membrane that is externally covered by numerous sets of microvilli.

Histopathological studies on the excised cysticercus demonstrated a nonviable, almost necrotic, vacuolated scolex with a still-viable cystic membrane (Fig. 2).
