Status post tumor resection. There has been interval left temporal lobe tumor resection with blood products and air in the surgical cavity. There is a subcentimeter enhancing nodule anterior to the resection cavity. There is also surrounding confluent T2 hyperintensity in the white matter. There is also scattered patchy cerebral white matter T2 hyperintensity elsewhere. There is a small area of restricted diffusion along the posteromedial aspect of the resection cavity and a punctate focus of apparent restricted diffusion in the left caudate. There is a punctate defect in the right basal ganglia without restricted diffusion, which may represent a chronic infarct. There is a probable small posterior corpus callosum developmental venous anomaly. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. There is an unchanged hypoplastic right cerebellar hemisphere. The major cerebral flow voids are grossly intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are unchanged.
1. Recent postoperative findings with apparent subcentimeter residual enhancing tumor along the anterior aspect of the left temporal resection cavity and surrounding confluent T2 hyperintensity.2. A punctate focus of apparent restricted diffusion in the left caudate may represent a recent infarct.
