CT scan of the abdomen and pelvis revealed a 10.2 x 10 cm multiloculated fluid collection extending from the head of the pancreas to the lower right psoas muscle, deviating the right colon (Fig. 1).
52 days after initial presentation (A) coronal and (B) axial MRCP show continued fluid collection extending from the dorsal aspect of the pancreatic body along the posterior aspect of the superior mesenteric artery and anterior margin of the right renal vein.
