Two intra-axial enhancing mass lesions are demonstrated, the larger of the two located in the white matter of the left precentral gyrus, measuring 25 mm, and the smaller of the two located on the right in the fusiform gyrus of the right temporal lobe, measuring 10 mm in diameter. These demonstrate pronounced signal loss on echoplanar imaging, and intrinsic high T1 signal, consistent with blood product. They are surrounded by a moderate amount of vasogenic oedema.
The remainder of the brain is unremarkable, with no other lesion is evident, and only a modest amount of chronic small vessel ischaemic white matter change.
Conclusion
Features are consistent with haemorrhagic metastases. Presence of multiple metastatic deposits are seen on CT, including subcutaneous deposit in the left buttock suggests malignant melanoma as the most likely primary.
