Male, 8 years old, with slurred speech, facial droop and aggressive behavior. The cerebral and cerebellar hemispheres and brainstem show normal signal intensity and morphology. No restricted diffusion is seen. The medial temporal lobe structures are free of any focal lesions or abnormal signal intensity. However, the left hippocampus demonstrates a relatively more rounded configuration along its body compared to the right side (see image 78 and image 83 of series 1502), with very slight asymmetric prominence of the temporal horn and a vertically oriented collateral sulcus.No evidence of parenchymal edema, mass, or mass effect is seen. There is no evidence of intracranial hemorrhage or abnormal extra-axial fluid. The ventricular system is normal in caliber and morphology. Signal intensity of the bone marrow is unremarkable. No significant abnormalities of the paranasal sinuses are detected.
1.No acute intracranial abnormality.2.Findings are seen suggestive of the possibility of incomplete hippocampal inversion on the left. The significance of this finding is uncertain as it is an occasional asymptomatic incidental finding.
