Please Help Me with This Case!
An 11-year-old boy was involved in a car accident and presented in a semicomatous state.
Clinically he was diagnosed as having sustained a diffuse axonal injury and was treated conservatively.
A brain MRI was performed one month following injury and a repeat one 1 year later.
Susceptibility WI at the one month interval showed multiple microhemorrhages in both frontal lobes.
The one year follow-up MRI showed diffuse, symmetric, confluent hyperintensities in the periventricular WM and these findings were not present on the initial MRI.
The question is whether the WM changes seen at the one-year follow up study are related to the diffuse axonal injury. … Continue reading >>

As you can see, the lesion is hyperintense on T2, hypointense on T1 and does not enhance. No calcifications are present and no there is no restricted diffusion .
The patient is 25 year old and has loss of short term memory and seizures.
Any input into the nature of the mass is welcome.… Continue reading >>
