Male, 12 years old. Reason: Evaluate lesion in right temporal lobe, evaluate stability and characterization History: Right temporal lobe lesion, seizure Motion somewhat degrades evaluation. The previously seen focus of susceptibility artifact in the right corona radiata (series 1002, image 109) appears unchanged. The previously described subcentimeter T2 hyperintense subcortical focus in the inferior right temporal lobe is unchanged from the prior study dated 06/12/2015. The lesion does not appear to suppress readily on FLAIR, although this in part could relate to slice selection. Evaluation for enhancement is markedly limited by local pulsation and motion artifacts. There is no mass effect or edema. The ventricles and basal cisterns are normal in size and configuration. No abnormal extra-axial fluid collection is identified. The midline structures and craniocervical junction are within normal limits. There is no diffusion abnormality. Normal flow-voids are demonstrated in the major intracranial vascular structures. The paranasal sinuses, mastoid air cells, and orbits are unremarkable.
1.A subcentimeter right temporal lobe T2 hyperintense focus is grossly stable although does not definitely appear to suppress on FLAIR. Differential is unchanged, although additional follow-up imaging at 3T, to include 3-D T1 postcontrast and 3-D FLAIR sequences provided the small size of the lesion, is recommended to confirm FLAIR characteristics and to more completely assess for associated enhancement.2.A stable nonspecific focus of susceptibility in the right corona radiata may represent sequelae of prior microhemorrhage or may represent a small cavernoma.
