Patient Data

Age: 90
Gender: Male
MRI

Chronic subdural hematoma is seen in the right side with a hematocrit level.

Multiple T2W/FLAIR high signal intensity lesions in the periventricular white matter represent chronic small vessel changes.

Case Discussion

Note how concentrated methemoglobin causes decreased signal in T2W and increased signal in T1W and FLAIR images. Also note the diffusion restriction effect of concentrated methemoglobin in the dependent portion of the subdural haematoma.
