AST 161 U/L (normal 5-45 U/L), GGT 705 U/L (normal 4-50 U/L), and ALP 593 U/L (normal 42-128 U/L), Albumin 37.6 g/L and Globulin 34 g/L, Bilirubin, serum CEA, and amylase in serum and urine were all within normal limits; oral glucose tolerance test was normal, the detection of HBV, HCV and HIV were all negative. A chest X-ray film and hypotonic duodenography showed normal. Abdominal ultrasound (US) examination revealed an irregular hypoechoic lesion of 6.6 cm x 4.4 cm in the head of pancreas, and with a calcification at the edge of the mass, and without dilation of bile duct system and pancreatic duct (Fig 1); color Doppler flow imaging did not demonstrate blood stream in the mass.
Enhanced CT imaging of pancreas. Contrast enhanced CT scan showed an inhomogeneous cystic mass with peripheral rim enhancement, involving the head and uncinate process of the pancreas; enlarged spleen and mild dilation of main pancreatic duct were also demonstrated.

The above-mentioned contrast enhanced CT scan showed a inhomogeneous cystic mass in the head and uncinate process of the pancreas with peripheral rim enhancement, the body and tail of pancreas were normal; the head of pancreas, spleen were enlarged, and mild dilation of main pancreatic duct was also demonstrated (Fig 2).
Abdominal CT imaging at 7-month follow-up. Pancreas was normal in the CT scan at 7-month duration of antituberculous therapy, but the enlarged spleen remained.
