Male, 13 years old. Reason: follow up structural abnormalities History: hyperintense T2 focus. The previously seen focus of susceptibility artifact in the right corona radiata appears unchanged. A lesion with edema. The previously described subcentimeter T2 hyperintense subcortical focus in the inferior right temporal lobe is unchanged. As before, this lesion does not appear to suppress readily with FLAIR technique. There is no abnormal associated enhancement. 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 stable although as before does not suppress with FLAIR technique. The differential is unchanged, most likely representing a neuroglial cyst or prominent perivascular space. Repeat imaging in 1 year to assess for stability is recommended.2.A stable nonspecific focus of susceptibility in the right corona radiata may represent sequelae of prior microhemorrhage or may represent a small cavernoma.
