View for chronic and acute subdural hematoma: fall from bed. There is a mildly T1 hyperintense and T2 hyperintense right frontoparietal subdural collection that measures up to 8 mm in thickness. There is also a globular area of high T1 and low T2 signal with susceptibility effect in the right superior frontal convexity subdural space that measures up to 15 mm. There is cerebrospinal fluid signal intensity left frontoparietal subdural fluid collection that measures up to 4 mm in thickness. There is an epidural fluid collection with high T1 and low T1 signal that measures up to 3 mm in thickness along the left parietal convexity. There is a punctate focus of susceptibility effect along a cortical vein corresponding to the subarachnoid hyperattenuation on the prior CT. There is minimal prominence of the bilateral anterior frontal subarachnoid spaces. There is no evidence of acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is a normal degree of myelination. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is right posterior subgaleal hematoma that measures up to 5 mm in thickness with an underlying linear defect in the right parietal bone and perhaps the right occipital bone, which correspond to the non-displaced fractures. The orbits are grossly unremarkable.
1. A small focus of acute subdural hemorrhage is present in the right superior frontal convexity superimposed upon what likely corresponds to a late frontoparietal convexity subdural hematoma.2. A left frontoparietal convexity fluid collection may represent a subdural hygroma versus a chronic subdural hematoma with superimposed small parietal convexity epidural hematoma.3. A punctate focus of susceptibility effect along a cortical vein corresponding to the subarachnoid hyperattenuation on the prior CT may represent subarachnoid hemorrhage.4. Minimal prominence of the bilateral frontal subarachnoid spaces.5. The known non-displaced posterior right skull fractures are better depicted on the prior CT.
