Female, 14 years old, with headaches for 2 years status post concussion. Assess for diffuse axonal injury. A single 4 mm focus of T2 hyperintensity is evident within the left aspect of the body of the corpus callosum (see image 19 series 701). This was present on the prior MRI examination from 2010 and has not significantly changed.The cerebral and cerebellar hemispheres and brainstem otherwise show normal signal intensity and morphology. No restricted diffusion is seen. The pattern of parenchymal enhancement is within normal limits.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.
A single 4 mm focus of signal abnormality is evident within the left aspect of the body of the corpus callosum, stable when compared to a prior examination from 2010. This finding is nonspecific.No additional evidence to suggest diffuse axonal injury or other significant posttraumatic injury to the brain.
