Subdural hemorrhage [432.1], Reason for Study: ^Reason: bilateral hygromas - assess any change in size or rehemorrhage History: headache There is no evidence of acute ischemic or hemorrhagic lesion on the scan.Redemonstration of bihemispheric subdural fluid collections (maximum diameter on coronal scan is about 10mm on the right and about 8mm on the left), no change since prior scan. There is no evidence of internal hemorrhage or enhancement.There are also subdural fluid collections on posterior fossa around cerebellar hemispheres, again no change since prior scan.There is no evidence abnormal enhancement or mass lesion.Ventricular system appears to be normal.There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. There are minimal to mild mucosal thickening on bilateral (left more than right) maxillary sinuses. Interval development of the right mastoid air cell opacifications.
1. No change of bihemispheric and posterior fossa subdural prominent fluid collections since prior scan.2. No evidence of air acute ischemic or hemorrhagic lesion on the scan.3. No evidence of abnormal enhancement. No mass lesion.
