Altered mental status, parietal subgaleal hematoma, pronator drift, anisocoria. Motion artifact degraded image quality.There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Multifocal scattered patch high signal intensities on FLAIR imaging on bilateral periventricular white matter and deep white matter indicate nonspecific small vessel ischemic disease.Right parietal subgaleal hematoma still seen, comparing to the CT scan, no significant interval change since prior scan performed on June 17, 2015.There are about 3.7 mm thickness bilateral subdural fluid collections with evidence of linear susceptibility artifacts on gradient echo images indicate chronic subdural hemorrhage. There is no evidence of mass effect towards brain parenchyma and from these fluid collection.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Non specific small vessel ischemic disease.3. Bihemispheric subdural fluid collections without mass effects toward brain parenchyma possibly represent chronic subdural hematoma.4. No change of right parietal subgaleal hematoma since prior CT scan.
