The supposed pathogenesis is that pancreatic enzymes enter the circulation and in some sites there is insufficient antitrypsin to counteract their effects; these sites are sites of inflammation already, for example secondary to minor trauma or even surgery. The good news in the case I am thinking of is that the abscess was identified and responded completely to appropriate antibiotics. I do not intend to suggest that your case was the same but it is an interesting and far from intuitive explanation that is worth being aware of in case of a next time.</p> <p>Gerry</p><div style="clear:both;"></div>
