case_images: The MRI scan showed only data of generalized atrophy (Figure 1) and the 18F-FDG PET/CT scan of the brain (Figure 2) showed decreased metabolism in the cortex of the primary motor area and bilateral premotor, bilateral anterior cingulate, mild to moderate right temporal neocortex in its polar portion with extension to the entorhinal cortex, both caudates, and the posterior third of the putamen.
case_images: Brain 18F-FGD PET/CT. (A) Axial and sagittal sections showing moderate to severe hypometabolism in the cortex of the primary motor area and bilateral premotor area (blue arrows), moderate hypometabolism in the bilateral anterior cingulate (yellow arrow), and mild to moderate hypometabolism in the right temporal neocortex in its polar portion with extension to the entorhinal cortex (white arrow). Basal nuclei with mild to moderate hypometabolism in the heads of both caudates (white arrowheads) and moderate hypometabolism of both putamen in their middle and posterior thirds (blue arrowheads). (B) Syngo Scenium corroborates hypometabolism in the bilateral motor and premotor cortex. (C,D) Coronal section showing hypometabolism in the primary motor cortex correlating with the cortical or Penfield homunculus.

case_images: 18F-PSMA-1007 PET/CT. (A) Axial slices of plain tomography without blastic bone lesions. (B) PET/CT shows focal areas of radiotracer uptake in the left posterior seventh costal arch and sacrum, without morphologic translation. (C) Maximum intensity projection with 18F-PSMA-1007.

case_images: Due to the antecedent of prostatic adenocarcinoma and suspicion of biochemical recurrence, an 18F-PSMA-1007 PET/CT scan was performed, which showed at least four bone-level uptake sites in the left seventh costal arch and sacrum without morphological translation (Figure 3).
