Summary:

Description
  • Radiopaedia case ID: 41814
  • Image ID: 18271401
  • Image stack position: 16/20
  • Plane projection: Sagittal
  • Aux modality: T1
  • Study description: MRI Brain
  • Study findings: Technique: Multiplanar multisequence imaging including pre- and post-contrast T1, T2, FLAIR, DWI/ADC and stereotaxis. Findings: There is a superficially located mass in the left superior frontal gyrus anteriorly measuring 22 x 13 x 20 mm (AP x LR x SI). This has developed in the region of subcortical FLAIR hyperintensity present on the previous MRI. The mass is centered on the grey-white matter junction involving both cortex and subcortical white matter and has a broad dural abutment. The mass demonstrates subtle intrinsic T1 hyperintensity and blooming consistent with blood product and heterogeneous solid contrast enhancement. The lesion is of heterogeneous T2 signal with mixed hyperintense and hypointense components. No central restricted diffusion in the mass. Extensive surrounding vasogenic edema in the left frontal and parietal lobes. There is associated mass effect on the left lateral ventricle and sulci and rightward midline shift of 7 mm. No other intracranial mass. No hydrocephalus. Conclusion: Left superior frontal gyrus mass associated with extensive vasogenic edema and mass effect most likely represents a metastasis.​
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Technique: Pre and post contrast images have been obtained through the brain. Findings: There is a left frontal paramedian cortical tumor that shows mild peripheral hyperattenuation and heterogeneous contrast enhancement. The lesion has a broad contact with the cerebral falx without disrupting it or dural tail sign. A prominent vasogenic edema is observed along the left frontal lobe associated with mass effect that promotes lateral ventricle compression and subfalcine herniation with mild midline shift. The remainder brain is unremarkable. Conclusion: Left frontal mass with a prominent vasogenic edema and mass effect most likely represents a metastasis.
