Summary:

Description
  • Radiopaedia case ID: 47576
  • Image ID: 24713559
  • Image stack position: 24/56
  • Plane projection: Axial
  • Aux modality: DWI
  • Study description: MRI Brain
  • Study findings: Centered in the right posterosuperior frontal lobe there is a mass that has mildly heterogeneous signal intensity but is mainly isointense to grey matter on T1 and T2-weighted images. Peripherally there is some diffusion restriction, with heterogeneous enhancement. Surrounding this there is vasogenic edema which does not have any significant mass effect with local sulcal effacement but no midline shift or cerebral parenchymal herniation. Cerebral blood volume (CBV) is increased around the periphery of the mass. Spectroscopy demonstrates depressed choline, creatine and NAA peaks with elevation of the lactate/lipid peaks within the mass (not shown above). In the surrounding vasogenic edema the spectroscopy traces are relatively normal. No further lesion is identified. Remainder of the brain is unremarkable.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Right frontal lobe circumscribed hyperdense mass showing vivid contrast enhancement and associated with surrounding vasogenic edema. No midline shift or cerebral herniations. Ventricles and basal cisterns are unremarkable. No skull lesions.
