 Good evening to everyone. My presentation is based report of unusual locations of pancreatic pseudocyst. My name is Bhuvanthi Krishna Reddy from Krishna Institute of Medical Sciences. A 35 years male presented with mild apricastic pain, came for CECT abdomen. With history of acute abdomen 15 days back and there is no any history of admission and he was treated locally. The laboratory parameter shows normal hemoglobin and elevated serum MLIs and serum and lipase levels. The clinical diagnosis was acute pancreatitis and in our department on the triple phase CECT abdomen and pelvis was done. Cross-sectional imaging on the delayed post-contrast studies. We can appreciate the peripheral enhancing hypodense lesion in the tail and body of the pancreas communicating with the main pancreatic. And the below section cross-sectional showing the peripheral enhancing lesions in the tail region which are communicating with the single lesions which are noted in the gastro-hypatic area along the lesser curvature. Coming to the sections of the liver, here we can see some hypodermal lesion in the insinate process is communicating with the biloval lesion in the corded of the liver. And down is the cross-sectional section in the venous phase showing the abrupt cut off of this pleinic vein which is a selective of thrombosis. On the cross-sectional, on the coronal section, delayed images and axial images, we can appreciate the multiple hypodense histic lesions which we have seen along the lesser sac. We're certainly extending into the posterior medastinum which we're almost adjacent to the left atrium. Coming on the post-continous etymogen, the pancreas appears to be atropic with the prominent main pancreatic duct. The multiple-localated peripherally enhancing hypodense lesions are noted predominantly in the tail and body of the pancreas. The few of them are communicating with the main pancreatic duct. This has also been communicating with the smaller cysts along the lesser sac extending superiorly into the posterior medastinum or posterior to the left atrium. One of the hypodense lesions in the unsanitary process is seen communicating with the bilobilated lesion in the corded lobe of the liver. This pleinic vein shows abrupt cut off in the distal aspect with multiple collaterals in the pleinic region. Pancreatic pseudo cysts are a complication of the pancreatitis defined as a collection of pancreatic juice and closed by a volume of non-hypothelized granulation tissue or fibrotic capsule. The pancreatic pseudo cyst formation is a common complication of pancreatitis. Commonly it is seen in the pancreatic and peripangreatic areas. Most of the pseudo cysts are located around the pancreatic gland, but they have also been described at the greater distance from the pancreas and the medastinum to scrotum when the fluid descends through the tissue plates. The medastinal pancreatic pseudo cyst is a rare complication of pancreatitis. This pleinic parenchymal involvement also been defined in the literature. A very rare location for a pseudo cyst during acute pancreatitis is in the liver with only few cases been previously described. The pancreatic pseudo cyst in the lumbar triangle, soias muscle and intercostal space and obturator externals also been described in the literature. The pseudo cyst may be a symptomatic or may present with variety of symptoms to the abdominal pain, nausea, vomiting, upper gait bleeding. The diagnosis of complications of pseudo cysts like infection, hemorrhage and cyst rupture can be diagnosed at earliest possible stage and reduce the morbidity of the patient. Coming to the conclusion, unusual locations of pancreatic pseudo cyst are very rare. On CT, the imaging, the extent of lesions and complications can be well established. One of the differences of the mass in the posterior medastinum should be kept as a pancreatic pseudo cyst in appropriate clinical settings. The management of the patient depends on unusual location of the pseudo cyst and the complications caused by it. The most of the cases can be managed conservatively. However, surgical interventions such as prenectomy, digital pancreaticomy and prudence drainage are also indicated in CBI cases. These are my references. Thank you.
