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

Cases of Cerebral Contusion

CT of cerebral contusion
Axial CT without contrast of the brain shows multiple high density punctate intraparenchymal lesions in the bilateral frontal lobes.
Radiograph of stellate skull fracture and CT of acute subdural hematoma due to accidental trauma
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.
