Mediastinum metastasis in a post-surgical pancreatic cancer patient successfully confirmed with endoscopic ultrasonography

[1,2,3] Imaging examinations like enhanced computed tomography (CT)/magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET-CT), play an important role in detecting tumor recurrence or residual after radical resection of pancreatic cancer. Laboratory results were as follows: platelets 373×109/L (normal [100-300]×109/L), blood glucose 9.89 mmol/L (normal 3.89-6.10 mmol/L), glycosuria test 3+; other parameters were within the normal range, such as white and red blood cell counts, blood electrolytes, aminopherase, bilirubin, amylase, and renal function. CA199 and CA50 levels were higher than normal levels (CA199 136.2 U/mL, normal 0-35 U/mL; CA50 43.97 ng/mL, normal 0-25 ng/mL). Because CA199 is commonly implicated in pancreatic cancer, we wanted to investigate the reason for increased CA199. [...]we arranged for chest, abdomen, and pelvis enhanced CT scan for the patient in our hospital.
