“…In the present study total regression of an acute pancreatic pseudocyst within 3 weeks was achieved in 1 patient in whom percutaneous antegrade drainage was performed twice. How ever, current studies have demonstrated a high spontaneous resolution rate of approximately 20% in acute pancreatic pseudocysts (2,19,22). Therefore, it is not clear whether or not the decompressive effect of puncture was res ponsible for the final disappearance of the cyst in this patient.…”

“…Sonography has continously gained impor tance as a non-invasive technique for initial diagnosis and follow-up o f pancreatic disease, particularly in view of its high accuracy of over 90% in the discrimination of cystic versus solid tumefaction of the gland (1,2). However, although three-dimensional delineation of solid masses is achieved, ultrasound does not permit reliable identification o f acoustic texture pat tern as benign or malignant.…”

20 percutaneous aspirations, guided by ultrasound, were performed without serious complications in 17 patients with cystic pancreatic lesions. Amylase activities of all 10 pseudocysts were increased with a considerably wide range (3,680–775,000 U/l) and the serum amylase level correlated significantly (p < 0.01) with the enzyme activity of cyst content. The enzyme level of 1 true cyst and 2 cystic malignancies were in the normal range of serum amylase; low amylase activity does not rule out a pancreatic origin of a cystic mass lesion. Bacteriological and cytological studies of aspirated samples revealed 2 (of 2) pancreatic abscesses and 2 (of 3) cystic malignancies. Total regression of an acute pancreatic pseudocyst was achieved following repeated percutaneous antegrade evacuations.

“…Recent reports from the ultrasonographic literature, however, would lead one to believe that spontaneous internal decompression of a pseudocyst into either the pancreatic ductal system or alimentary tract may be more comnion and less lethal than previously believed. Spontaneous gradual resolution has been reported by Gonzales and coworkers in 1 3 out of 49 cases studied (27%) (7). The abdominal fluid that develops in patients with rupturing pseudocysts can be differentiated from cirrhotic ascitic fluid because of its elevated amylase and protein content.…”

“…Second, ultrasound can readily differentiate cystic from solid structures, thereby H Ilowing physicians to distinguish pseudocysts from edematous pancreatic tissue. In several recent studies, the accuracy of ultrasound in the diagnosis of pancreatic pseudocysts has ranged between 85 and 100% (7)(8)(9).…”

Ultrasonograms of most pseudocysts have a typical appearance--sharply defined, smooth wall, ovoid, located in the region of the pancreas. However, in reviewing the sonographic appearance of pseudocysts, other ultrasonographic characteristics may occasionally be encountered. Eleven patients with atypical pseudocysts are presented. The demonstration of multiple septations, multiple echoes within a sonolucent mass, and even failure to enhance posteriorly should not exclude the diagnosis of pancreatic pseudocyst in the proper clinical setting. The value of serial scans is also stressed. In this series, it was possible to suggest the diagnosis of infection, hemorrhage, and rupture of pseudocysts by demonstrating cysts with more typical appearances on prior examinations.

“…It is more accurate than CT in nonobese patients [3,8,9,16,17]. In a comprehensive survey of the literature we could not find any report about the value of ultrasonography in cases of bleeding into the pancreatic pseudocyst, except for showing a sudden increase in size and pulsation of the pseudocyst [1,6,18].…”

Bleeding into a pancreatic pseudocyst is a rare but life-threatening entity. Early diagnosis is crucial in its management. There are reports suggesting that computed tomography (CT), scintigraphy, endoscopic retrograde cholangiopancreatography (ERCP), and angiography could be the diagnostic maneuvers. In this report, we present a case of arterial bleeding into a pancreatic pseudocyst, which was diagnosed by the turbulent echo-currents seen in real-time ultrasonography.
