Male, 19 years old, with history of cerebral cavernous malformation status post resection. Surveillance imaging. Evidence of a left temporal surgical resection is again seen. An obliquely oriented resection cavity traverses the anterior temporal lobe showing interval decrease in size. Encephalomalacia of the surrounding anterior temporal gyri is also seen.Thickening of the left the medulla is again seen with susceptibility effect at the uncus. Ill-defined enhancement on a background of mild intrinsic T1 hyperintensity is also seen centered on the uncus.No new intracranial lesions are detected. No areas of significant parenchymal edema or mass effect are seen. The ventricles remain normal in size and morphology.
Postoperative findings are redemonstrated within the anterior left temporal lobe. Areas of associated parenchymal signal abnormality have not significantly changed from the prior exam. No new intracranial lesions are seen.
