Pediatric Cerebral Contusion
Etiology: trauma
Imaging: cortex under impact (coup), cortex opposite side of impact (contra coup), often hemorrhagic, gliding contusion common at frontal bone and temporal tips
Radiology Cases of Cerebral Contusion
Axial CT without contrast of the brain shows multiple high density punctate intraparenchymal lesions in the bilateral frontal lobes.Axial CT without contrast of the brain (left) shows a subgaleal hematoma anteriorly along with pneumocephalus and multiple areas of high density in the frontal lobes. Examination of the bone windows at the same level (right) shows multiple non-depressed fractures of the frontal bone.AP and lateral radiographs of the skull show numerous branching lucencies in the right parietal bone. Axial CT without contrast of the brain shows high density material in the right subgaleal tissues, a small high density cresenteric fluid collection in the right extra-axial space that extends posteriorly along the falx, and a mixed low-density and high density lesion in the right posterior parietal brain parenchyma.
