Pseudotumoral chronic pancreatitis

Pseudotumoral chronic pancreatitis Feb 23, 2009
A 47-year-old man presented with upper abdominal pain and severe weight loss. EUS showed an inhomogenous, pseudotumoral pancreatic head mass, with discrete power Doppler signals inside. EUS-guided FNA showed only benign canalicular cells. Long-term follow-up of more than 12 months confirmed the benign nature and absence of malignancy.

Pseudotumoral chronic pancreatitis Feb 23, 2009
A 5o-years-old patient, with a long history of alcohol consumption, presented in the Emergency Unit for intractable pain and vomiting. EUS revealed a hypoechoic, inhomogeneous pancreatic head mass, with a diameter of ~ 3 cm. EUS-FNA with cytological exam revealed only inflammatory cells. Rich peripancreatic vascularisation was revealed in power Doppler after contrast injection with Sonovue.
 

Pseudotumoral alcoholic chronic pancreatitis Feb 5, 2005
Young patient with enlarged (50/45 mm) pancreatic head, compressing the antral region, visualized during CT. EUS with power Doppler showed intense vascularization of the pseudotumor, while EUS-FNA with cytological analysis was negative for atypical cells.

Patient with a pseudotumoral mass at the level of the pancreatic head, compressing the duodenal bulb. EUS showed a cystic structure with thick wall and intense vascularization depicted on power Doppler EUS. EUS-FNA was negative for atypical cells and the case was interpreted as a pseudocyst in the context of chronic pancreatitis.
