T1 WI postgadobutrol administration sagittal slices. (a, d) Nodular enhancing lesions between 1 and 4 mm (arrows) at the centrum semiovale and left cerebellar hemisphere. Additional leptomeningeal enhancement was noticed at the pial surface of the left posterior quadrant (arrows). (b, e) Images obtained 7 months later. There is evident reduction in lesion size, and fewer leptomeningeal enhancement is noticed. (c, f) Images obtained 11 months from first study; no lesions or enhancement noted.

Follow-up images at 3, 6, and 12 months of treatment showed partial response of extracranial, CNS, and leptomeningeal lesions (Figures 1 and 2).
18-FDG PET CT fusion images: axial and sagittal slices. (a, d) Right upper lobe mass with abnormally increased metabolism with surrounding lymphangitic carcinomatosis on both upper lobes with increased metabolic activity as well. On sagittal slices, multiple mixed type (blastic/lytic) metastatic lesions affecting axial skeleton. (b, e) Images obtained 7 months later showed marked decrease on metabolic activity on both pulmonary and skeletal lesions. (c, f) Images obtained 11 months from first study demonstrate the absence of metabolic activity on both primary site and spinal lesion.
