Presentation

Alcohol excess. Raised PT. Cirrhosis?

Patient Data

Age: 40 years
Gender: Male
x-ray

Speckled calcification in the left upper quadrant.

Mass effect on the transverse colon which is displaced inferiorly.

Dilated gas-filled transverse colon, without obstruction, suggests a localised ileus.

ultrasound

At the region of the head of the pancreas, there is a well-defined, rounded area measuring 4 cm which fills with vascularity on the application of colour doppler. This is surrounded by inflammatory soft tissue. Unable to determine the exact nature/source on ultrasound but considering the patient's history of pancreatitis, this may represent pseudoaneurysm. 

The liver appears echogenic with a coarse echotexture suggestive of intrinsic liver disease. No focal liver lesion. Antegrade portal venous flow. 

Extensive pancreatic calcification. The pancreas is very atrophic with marked dilatation of the pancreatic duct and marked side branch dilatation.

No active bleeding.

Moderate intra and extrahepatic duct dilatation with the CBD measuring up to 9 mm. The CBD is compressed by this pseudoaneurysm. Deviation of the duodenum/pylorus and there is some inflammatory stranding.

No focal liver lesions. The spleen, kidneys and adrenal glands are unremarkable.

No free fluid in the abdomen or pelvis.

Case Discussion

Pseudoaneurysms are a recognised complication of severe pancreatitis. This patient was transferred to a tertiary facility and underwent successful coil embolisation.
