 Note that the limited obtained sequences, including sagittal T1, diffusion weighted imaging, and FLAIR sequences are significantly degraded by patient motion. Diffusion-weighted images demonstrate a focus of diffusion restriction in the right frontal lobe corresponding with focus of hypoattenuation adjacent to the recently placed ventriculostomy catheter, compatible with a small infarct. Bilateral subdural collections again seen. Left parietal encephalomalacia. Ventricular system is decompressed. The examination otherwise nondiagnostic.
Significantly limited examination. There is a focus of restricted diffusion in the right frontal lobe adjacent to the ventriculostomy catheter which is compatible with acute/early subacute infarct. This infarct corresponds to a focus of hypoattenuation that can be seen on head CT exams dating back to 5/17/2015. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
