Injury, unspecified [T14.90], Reason for Study: ^Reason: brain parenchyma, structural lesions History: non accidental injury with subdural hematoma and parietal contusion There are bilateral temporal subdural blood products with varying age. In addition, adjacent temporal lobes' show subtle volume decrease and T2/FLAIR high signal intensities on white matter indicating possible associated myelomalacia. Especially mainly bilateral middle and inferior temporal gyri show gyriform T1 high signal intensity lesions which may indicate associated cortical contusion.Similar finding is also seen on the left parietal lobe. A couple of susceptibility lesions including right frontal lobe (series 1102, image 37, image 43) may indicate parenchymal focal petechial hemorrhage.Previously seen right occipital bone fracture and right side subgaleal hematoma around the right mastoid are not conspicuous on today's MRI. 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. Various aged bitemporal subdural hematoma associated with findings suggesting possible contusion on bilateral temporal lobes and left parietal lobe.2. Bifrontal focal susceptibility lesions may indicate brain parenchymal petechial hemorrhages.
