(b) MRI of the brain (T2-weighted axial image) showing the solitary brain metastasis consisting of a 2.7 cm nodular component with perilesional edema and hemorrhagic characteristics: susceptibility artifacts with foci of signal loss on T2-gradient echo sequence in the peripheral part of the nodule. (c, d) 18F-FDG PET/CT showing FDG avidity and extent of the bilateral pulmonary tumoral sites with physiologic uptake in the urinary tract.
