There is am intraaxial peripherally enhancing mass in the peripheral right middle frontal gyrus. There is surrounding abnormal hyperintensity in the surrounding right frontal white matter consistent with vasogenic oedema. Blooming on gradient echo sequence indicate the presence of blood products within the mass. Diffusion weighted imaging sequences difficult to interpret any presence of blood products.
A second smaller focus of enhancement is present anterior and medial to the larger lesion.
Previous right posterior cerebral artery territory infarct.
Conclusion: Two closely related enhancing intra-axial masses in the right frontal lobe either represent haemorrhagic metastases or a haemorrhagic high grade glial tumour (GBM).
