“…Focal pancreatitis can occur in as many as 18% of cases of acute pancreatitis [13]. Focal pancreatitis can mimic anatomic imaging findings associated with pancreatic carcinoma such as obstructive jaundice or vascular encasement [10,14]. Early series reported very few false-positives due to focal FDG uptake, and of those most were attributed to processes potentially associated with inflammation such as hemorrhagic pseudocyst, portal vein thrombosis, or presence of a stent [5], or were distinctive due to atypical location of the focal FDG uptake such as divisum or retroperitoneal fibrosis [1].…”

Focal 2-deoxy-2[fluorine-18]fluoro-D-glucose (FDG) uptake on positron emission tomography (PET) in a pancreatic mass has been reported as a specific finding for pancreatic carcinoma. Inflammatory conditions of the pancreas and associated clinical circumstances yielding similar findings have not yet been fully defined. Among 42 patients studied by attenuation-corrected FDG PET for pancreatic disease, 12 with focal FDG uptake in the pancreas were identified as having no underlying neoplasm based on surgical findings, biopsy results, and long term clinical and imaging follow up. Focal FDG accumulation in the pancreas with standardized uptake values ranging from 3.4 to 11.2 on FDG PET was ultimately found to be related to inflammation rather than neoplasm. This occurred in pancreatic masses in which clinical and laboratory evidence of acute pancreatitis was equivocal or entirely lacking, as well as in the setting of acute pancreatitis and after recovery from acute pancreatitis. Inflammation can give rise to focal FDG uptake in the same intensity range as pancreatic neoplasm, even when clinical, laboratory and computed tomographic findings suggestive of an inflammatory etiology are equivocal or absent.

“…Only an occasional case report is found in the literature in which the periarterial fat is obliterated in acute pancreatitis. 4 Formation of a pseudoaneurysm in pancreatitis has been documented by CT. It has been estimated to occur in as high as 10% of patients with pancreatitis.…”

Extrapancreatic fluid collections are frequently seen in acute pancreatitis. Vascular damage with life-threatening hemorrhage is also a known complication. In the case report presented, we include documentation by computed tomography of an apparent abdominal aortic wall dissection by fluid in a patient with acute pancreatitis. Conservative therapy resulted in complete resolution without hemorrhage or aneurysm formation.

“…45 But this can also be seen in AIP or IgG4 (immunoglobulin G4 related) conditions with extrapancreatic lesions in sclerosing mesenteritis and retroperitoneal fibrosis. 46 Adenocarcinoma developing in the background of chronic pancreatitis is difficult to detect on imaging. In the context of chronic pancreatitis, calcifications displaced by the mass is a pointer suggesting a coexisting PC.…”

There has been significant increase in the detection of incidental pancreatic lesions due to widespread use of cross-sectional imaging like computed tomography and magnetic resonance imaging supplemented with improvements in imaging resolution. Hence, accurate diagnosis (benign, borderline, or malignant lesion) and adequate follow-up is advised for these incidentally detected pancreatic lesions. In this article, we would review the various pancreatic parenchymal (cystic or solid) and ductal lesions (congenital or pathological), discuss the algorithmic approach in management of incidental pancreatic lesions, and highlight the key imaging features for accurate diagnosis.
