Learning objectives
-Demostrate CT findings of groove pancreatitis
-Different diagnosis of paraduodenal pancreatitis such as pancreatic adenocarsinoma,
ampullary carsinoma,
duodenal adenocarcinoma etc.
Background
- Paraduodenal pancreatitis is a term that has been proposed as a global category which includes GP,
cystic dystrophy of the duodenal wall and paraduodenal wall cysts,
because this entities have several features in common
- The proposed mechanisms for development of groove pancreatitis is disruption of the pancreatic secretion through the minor papilla due to a disturbed Santorini duct which may be due to chronic alcohol consumption or pancreatic heterotopia within the duodenum or the minor papilla with leakage of digestive enzymes into the...
Findings and procedure details
PANCREATİCODUODENAL GROOVE:
- Pancreatic groove is a theoretical space defined by pancreatic head (medially),
2 nd portion of duodenum (laterally),
3 rd portion of duodenum and IVC (posteriorly),
and duodenal bulb (superiorly) also contains distal CBD,
main/accessory pancreatic ducts,
and major/minor papilla (Fig 1)
- Chronic pancreatitis affecting pancreaticoduodenal groove
Pure form (sheet like): affects only pancreaticoduodenal groove
Segmental form (mass like): affects pancreaticoduodenal groove and extends medially into pancreatic head
IMAGING FEATURES:
- İll–defined fat stranding and inflamatory change to frank soft tissue in...
Conclusion
* Paraduodenal pancreatitis is an uncommon type of focal chronic pancreatitis affecting the groove between the head of the pancreas,
the duodenum and the common bile duct
* Clinical and imaging features of paraduodenal pancreatitis can mimic multiple disease and
It is important to distinguish between malignant processes such as pancreatic adenocarcinoma
* The most specific imaging features of paraduodenal pancreatitis,
including duodenal wall thickening,
enhancement,
and cystic change,
reflect the underlying pathophysiology and anatomy
