Summary:

Description
  • Radiopaedia case ID: 40224
  • Image ID: 16529422
  • Image stack position: 23/34
  • Plane projection: Axial
  • Aux modality: non-contrast
  • Study description: CT Brain - Day 1
  • Study findings: Non contrast study. Comparison made to the study from earlier in the day.Numerous, multifocal bifrontal parenchymal hematomas, more marked on the right and more prominent than scan earlier today. Right anterior and lateral temporal and left cerebellar parenchymal hematomas. Stable mass effect with effacement of the right lateral ventricle and midline shift to the left when compared to the earlier scan today . Further dilatation of the temporal horn of the left lateral ventricle.The ventricles are otherwise unchanged in size but slightly increased when compared. Loss of gray /white differentiation of right lentifrom nuclei and inferio temporal lobe The basal cisterns are effaced. Skull fractures previously described.
  • Modality: CT
  • System: Central Nervous System
  • Findings: Bilateral frontal contusions, worse on the right. Subarachnoid hemorrhage over the right frontal lobe are noted in the sylvian fissures bilaterally. There is midline shift to the left of 3 mm. The basal cisterns are effaced. Left posterior fossa hemorrhage is probably extra-axial. Bilateral subtle skull base bone fractures which do not extend to the occipital condyles. On the right, the occipital fracture extends into the right jugular foramen through the vestibular apparatus across the facial nerve canal and in the right temporomandibular joint. The fracture also involves the right carotid canal. There are locules of gas seen within the semi circular canals. Blood fills the right middle ear cleft.
