A few prominent lymph nodes were seen within the mesorectum, para-aortic, and porta-hepatis, with the largest of the para-aortic group measuring approximately 17x22 mm (Figure 1A). Multiple hypodense lesions in the liver ranged from 5 mm to 37 mm (Figure 1B).

Echocardiography showed a filling defect within the RV measured about 19 x 10.5 mm, without pleural effusion or pneumothorax (Figure 2A). Chest CT scan showed a filling defect within the RV measuring about 19 x 10.5 mm, without lung mass, pleural effusion, or pneumothorax (Figure 2B).
A) changes in metastatic liver lesions evaluated by computed tomography during chemotherapy at five months; B) abdominal computed tomography scan showing common bile duct dilatation (arrow); C) follow-up abdominal computed tomography at nine months showing no regression in mass size

Follow-up and outcome: the patient completed three cycles of FOLFOX chemotherapy with mixed responses, a drop of CEA from 17 ng/mL to 11 ng/mL, an almost normal level, and some radiological regression of liver lesions (Figure 3A). Abdominal CT scan showed a distended gallbladder measuring about 12 cm in long axis with no obvious wall thickening or adjacent fat stranding or free fluid (Figure 3B). A nine-month follow-up CT scan showed disease progression (Figure 3C), with a rise of CEA from 11 ng/mL to 41 and CA 19.9 from 14 ng/mL to 19 ng/mL.
