Summary:

Description
  • Radiopaedia case ID: 84371
  • Image ID: 53934673
  • Image stack position: 14/69
  • Plane projection: Coronal
  • Aux modality: non-contrast
  • Study description: CT head non-contrast
  • Modality: CT
  • System: Central Nervous System
  • Findings: Right intra-axial hematoma within the right frontal-temporal region measuring 62 mm in maximum dimension. Peri hematoma edema.Subarachnoid blood in the basal cisterns, extending into the Sylvian fissures bilaterally and along the right frontal lobe sulci. Further subarachnoid blood in the pre-pontine cistern. No frank intraventricular blood. Near complete effacement of right lateral ventricle. Approximately 7 mm midline shift to the left. Prominence of the temporal horns particularly in the left lateral ventricle, is suggestive of a degree of early hydrocephalus. Likely right uncal herniation. No cerebellar tonsillar descent. No acute infarcts.Opinion: Extensive subarachnoid blood, and large right frontal temporal intra-axial hematoma. Given the extent of subarachnoid blood, the intra-axial hemorrhage more likely represents parenchymal extension of an aneurysmal subarachnoid hemorrhage rather than a primarily intra-axial hemorrhage with secondary subarachnoid extension - further evaluation with CT intracranial angiogram is advised.Likely early hydrocephalus and midline shift.
