Female, 13 years old, with seizures. Findings related to prior left-sided craniotomy are redemonstrated. Sequelae of partial left temporal lobe resection are seen including the anterior portion of the left hippocampus. The surgical resection cavity, and the tissues immediately surrounding the cavity, are unchanged in appearance. In addition, the posterior aspect of the left hippocampus remains T2 hyperintense similar to prior.The right mesial temporal lobe structures are unremarkable. No additionally new lesions are detected. No pathologic parenchymal or extra-axial enhancement is seen. There is no evidence of intracranial hemorrhage or any new abnormal extra-axial fluid collection. Some sequences are substantially degraded by metallic artifact from presumed orthodontic braces. In particular, the susceptibility weighted sequence is significantly degraded and the diffusion-weighted sequence is nondiagnostic.The paranasal sinuses are poorly visualized due to this artifact, but significant mucosal inflammation is suspected within the right frontal sinus, the right sphenoid sinus, and the ethmoid air cells.
Sequelae of partial left temporal lobe resection are redemonstrated without significant change. Signal abnormality within the residual left hippocampus is also unchanged.No new or acute intracranial findings are detected.
