The following imaging features were analyzed: location (head including uncinated process, body, or tail), size, extent (focal or diffuse), and presence of intraductal solid tumor, attenuation/signal intensity/echogenicity of solid nodule compared with those of the normal pancreatic parenchyma, main pancreatic duct dilatation, chronic pancreatitis, pancreatolithiasis, presence of diffusion restriction on MRI, and FDG uptake on PET-CT.
Four of 5 (80%) patients with ITPN associated with invasive carcinoma had pancreatic duct dilatation greater than 10 mm and 3 of 5 patients had impacted pancreatolithiasis. The 3 patients without invasive carcinoma did not have pancreatolithiasis.
From May 2005 to November 2013,148 chronic pancreatitis and pancreatolithiasis
patients were treated by endoscopic stone extraction and ESWL at Toho University Omori Medical Center, Tokyo, Japan.

: a case report," Hepatogastroenterology, vol.
Pancreatolithiasis, pseudocyst of the pancreas, trauma and rupture of primary splenic aneurysms have been identified as other uncommon causes [4-7].

They went on to recommend that preoperative radiation be abandoned in patients who show evidence of pancreatolithiasis
(a marker of chronic pancreatitis) on radiographic studies.
Moreover, some patients with ampullary carcinomas had accompanying pancreatolithiasis.[18-20] The pathogenesis of this condition is explained by tumor stenosis of the main pancreatic duct, stagnation of the pancreatic juice, and constitutional changes in the pancreatic juice.
