case_images: The patient underwent an MRI scan that demonstrated a solid cum cystic lesion with only contrast enhancing cyst wall [Figures 1 and 2].
case_images: (a) Large and well encapsulated lesion in the right parietotemporal region which was adherent tentorium cerebelli and medially to midbrain. (b) Capsule of the lesion along with blood clot.

case_images: The intraoperative findings were large and well-encapsulated lesion in the right parietotemporal region which was adherent tentorium cerebelli and medially to midbrain [Figure 3a]; the opening pressure at ventriculostomy was not raised. A large abnormal thrombosed cortical vein was ending into the cystic part of the lesion, with the lumen filled with a clot [Figure 3b].
case_images: Section shows thick blood vessel lined by endothelial cells. Lumen of vessel shows organizing thrombus along with recanalization.

case_images: The vein was excised and final biopsy of the specimen was reported as a thick blood-filled vessel lined by endothelial cells and filled with organizing thrombus, showing recanalization [Figure 4].
case_images: Postoperative axial CT scan showing no residual lesion with dilated ventricles and the right-sided small subdural hematoma.
