Summary:

Description	Radiopaedia case ID: 54718 Image ID: 31714465 Image stack position: 25/54 Plane projection: Axial Aux modality: T1 C+ fat sat Modality: MRI System: Central Nervous System Findings: A peripherally enhancing mass at the grey-white matter junction of the supramarginal gyrus with significant surrounding edema. Central diffusion restriction is likely secondary to blood products admixed with proteinacous necrotic material. Conclusion: The differential is primarily that of a hemorrhagic metastasis (e.g. melanoma). A cavernoma would not be expected to have this degree of enhancement or diffusion restriction. An abscess is possible but the degree of signal loss is more consistent with blood than the thin low T2 rim seen in abscesses.
