How are pancreatic pseudocysts diagnosed?
Pseudocysts are diagnosed with blood tests and imaging studies that include abdominal ultrasound, abdominal CT scan or MRI, ERCP with endoscopic ultrasound, or MRCP. Your gastroenterologist also can take a sample of cystic fluid with a fine needle passed through the ERCP. Pseudocyst fluid is tested for the presence of cancer cells and proteins produced by cancer cells.
