FINDINGS: Status post left high frontoparietal craniotomy with near-complete resection of the mass lesion noted along the medial aspect of the left parietal lobe. A small hypodensity is seen adjacent to the splenium of the corpus callosum, which is suspicious for the residual tumor and needs further evaluation with contrast-enhanced MRI brain after the resolution of the hemorrhagic changes. Postsurgical changes in the left cerebral hemisphere.
