Hemorrhagic pancreatitis
Updates to Article Attributes
Haemorrhagic pancreatitis is a possible uncommon complication that can occur with pancreatitis and is characterised by bleeding within or around the pancreas. It is usually considered a late sequela of acute pancreatitis. This term was more often used in the early era to describe the blood found at laparotomy within the necrotic pancreatic & peripancreatic tissue.
Pathology
Haemorrhage can occur in patients with severe necrotising pancreatitis or as a result of pancreatic pseudoaneurysm rupture when it constitutes a life-threatening emergency.
Aetiology
According to one study, the usual causes of haemorrhage were 2:
- bleeding pancreatic pseudoaneurysm
/or peripancreatic pseudoaneurysm: ~60% - diffuse bleeding with pancreatic necrosis: ~20%
- haemorrhagic pancreatic pseudocysts: ~20%
Radiographic features
CT
Acute haemorrhage typically has high attenuation on unenhanced CT scans. The attenuation value then decreases as the haematoma ages through time 5.
MRI
Haemorrhagic fluid collections are more evident on MRI than CT due to the following reasons 1:
- T1: high-signal intensity methaemoglobin
- T2: low-signal intensity haemosiderin rim
Signal abnormalities due to haemorrhage remain visible longer on MRI than on CT.
