Patient with skull fracture, CT concerning for subacute hemorrhage. There are minimal foci of subarachnoid hemorrhage in the bilateral posterior frontal and anterior parietal convexities near the vertex as seen on recent CT. No evidence of intraparenchymal hemorrhage or edema. There is mild prominence of extra-axial CSF spaces along the cerebral convexities which are favored to represent mildly prominent subarachnoid spaces. No findings to suggest an acute subdural hemorrhage. There is redemonstration of left parietal convexity subgaleal hematoma measuring up to approximately 5 mm in greatest thickness. Skull fractures are better appreciated on prior CT. Myelination is appropriate for the stated age. Brain parenchyma appears within normal limits. 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.
1. Minimal foci of subarachnoid hemorrhage are again seen along the superior frontoparietal convexities near the vertex. No evidence of parenchymal hemorrhage or edema.2. Mild prominence of the extra-axial spaces along the cerebral convexities likely represent normal subarachnoid spaces. FLAIR sequences were not obtained and may be helpful to exclude the less likely possibility of subdural hemorrhage.3. Calvarial fractures are better evaluated on prior CT dated 4/8/2016.4. Left parietal scalp hematoma, similar to prior.
