Subsequently, for a better characterization of the cerebellar lesion, brain magnetic resonance imaging (MRI) was performed revealing multiple bilateral lesions with strong and irregular contrast enhancement, central necrosis, and mass effect, suggesting cerebellar metastases (Figure 2).
Cervical-thoracic-abdominal-pelvic computed tomography revealed parietal contrast enhancement without intraluminal well-defined mass at the distal common bile duct level with upstream dilatation of the extrahepatic and intrahepatic bile ducts.

The narrowed segment of the bile duct showed a parietal contrast enhancement without well-defined intraluminal mass (Figure 3).
18-Fluorodeoxyglucose positron emission tomography revealing a hypermetabolic lesion at the common bile duct/duodenum topography with cerebellar, thoracic-abdominal lymph nodes, left suprarenal gland, and bone metastasis.

Positron emission tomography scan (PET) with 18-fluorodeoxyglucose was performed revealing a hypermetabolic lesion at the common bile duct/duodenum topography with cerebellar metastasis and, additionally, other secondary lesions in the thoracic-abdominal lymph nodes, left suprarenal gland, and multiple bone sites (Figure 4).
