Postoperative T1 weighted MRI with contrast inversion prepared gradient echo coronal section of the brain and cryolesion. A large, well-defined lesion (blue arrow) is seen cranial to the right ventricle with a thin contrast enhancement peripherally. From the burr hole and into the cryolesion, a wedge-shaped lesion (yellow arrow) is seen, which is compatible with the spongostan used to close after the procedure.
