Subdural hemorrhage [432.1], Reason for Study: ^Reason: eval for cause of lt temporal seizures, possibly infarction vs lesion, pt s/p sdh evac History: lt temporal seizures Brain MRI:Motion artifact significantly degraded image quality. There bihemispheric subdural hematoma, more on the right side than left with mass effect and midline shift toward left side (9.9 mm at the level of foramen of Monro). There is evidence of right frontal burr hole with evacuation of hematoma on the right side. There is no evidence of acute ischemic lesion on the scan.The paranasal sinuses and mastoid air cells are clear.Brain MRV3D MRV brain without and with gadolinium enhanced scans with maximum intensity projections demonstrate normal flow enhancement in the superior sagittal sinus, internal cerebral veins, vein of Galen and straight sinus.The left transverse sinus and left sigmoid sinus as well as left jugular bulb appear to be hypoplastic. This could represent normal variation.
1. Bihemispheric Acute SDH with post burr hole evaluation of the right SDH.2. Midline shift toward right side, no significant interval change since prior CT scan.3. No evidence of acute ischemic lesion.4. Hypoplastic left transverse and sigmoid sinuses as described above.
