Portal annular pancreas: An unsual pancreatic pseudotumor with clinical significance

Portal annular pancreas (PAP) is a rare congenital anomaly due to abnormal fusion of ventral pancreatic bud left to the developing portal vein. Its incidence is 1.1%–3.4% in the literature. PAP is commonly involving the uncinate process; complete encircling is relatively rare. Proposed hypothesis fo...
