Overview

Head CT scan may be helpful in the diagnosis of intracerebral metastases. Findings on CT scan suggestive of intracerebral metastases include an iso- to hypodense mass with zero to marked peritumoral edema. On contrast administration, variable enhancement (intense, punctuate, nodular, or ring-enhanced) may be present.[1]

CT

  • Head CT scan may be helpful in the diagnosis of intracerebral metastases.[1]
  • Findings on CT scan suggestive of intracerebral metastases include:[1]
  • Non-enhanced CT (NECT): Iso- to hypodense mass with zero to marked peritumoral edema
  • Contrast-enhanced CT (CECT): Enhancement is also variable and can be intense, punctuate, nodular, or ring-enhanced if the tumor has outgrown it's blood supply
