 There is a 12 mm transverse x 9 mm AP x 7 mm craniocaudal lesion within the mesial left temporal lobe demonstrating primarily central T2 hyperintensity, T1 hypointensity, with surrounding parenchymal T2 hypointensity, also demonstrating susceptibility abnormality. There is no perilesional edema or associated developmental venous anomaly. There are no other similar appearing lesions.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for acute intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Mucosal thickening is present in the left maxillary sinus. Otherwise the remaining paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
Left mesial temporal lobe cavernous reformation.
