Status post right frontal craniotomy for recurrent brain neoplasm. There are postoperative findings related to recent right craniotomy for resection of a larger portion of the right frontal lobe air and fluid with in the resection cavity and deep to the craniotomy flap. There are also multiple areas of restricted diffusion and susceptibility effect along the surgical margins. There is also susceptibility effect within the ventricular system. There are residual areas of confluent high T2 signal surrounding the resection cavity, with extension into the left cerebral hemisphere. There are mildly prominent vessels and dural enhancement in the vicinity of the resection cavity, as well as patchy mild enhancement in the right basal ganglia that may attributable to hyperemia. Otherwise there is no evidence of residual enhancing tumor components. The ventricles are unchanged in size and configuration and there is unchanged slight midline shift to the right.
Recent postoperative findings with scattered areas of intracranial hemorrhage, but no definite evidence of residual enhancing tumor components.
