Male, 76 years old, with subdural hemorrhage. Evaluate for structural lesions. A T1 hyperintense, susceptibility inducing subdural collection is evident along the left parietal lobe with smaller quantities along the left occipital and temporal lobes as well. The collection measures up to 10 mm in thickness which is not significantly changed from prior CT. No new areas of hemorrhage are suspected.Extensive patchy periventricular T2 hyperintensity is seen. No edema or mass effect is detected. The sulci are prominent compatible with underlying parenchymal volume loss. The ventricles are within normal limits. Marrow signal of the calvarium is unremarkable.
Redemonstration of a subacute subdural hematoma predominantly located along the left parietal lobe with smaller quantities present along the left occipital and temporal lobes. No significant interval change in size is seen. No associated or underlying lesions are detected.
