Male, 9 years old, with staring spells and right leg and arm numbness. The left amygdala is subjectively thicker than the right with very questionable mild FLAIR hyperintensity. No masslike lesion is seen in either medial temporal lobe. No corresponding pathologic enhancement is detected. The hippocampal bodies are relatively symmetric and unremarkable.Elsewhere in the brain, no structural abnormalities are detected. There are no areas of abnormal parenchymal signal intensity. No evidence of intracranial hemorrhage or any abnormal extra axial fluid collection is observed. The ventricles are normal in size and morphology. The pattern of parenchymal enhancement is within normal limits.
1.Asymmetry of the amygdalae is seen, left side thicker than right. The significance of this finding is uncertain and correlation with EEG data is recommended when available. A general differential for this finding would include normal anatomic variation, post ictal effect, a manifestation of MTS, or even a neoplastic process. A follow-up examination in three to six months is suggested.2.The remainder of the brain is free of signal abnormality, structural deformity or pathologic enhancement.
