Pancreatic pseudocyst - Diagnostic ultrasound cases

US examination, pancreatic pseudocysts appear as anechoic structures associated with acoustic enhancement . Pseudocysts are well defined and round or oval, and they are contained within a smooth wall. During the early phases of their development, pseudocysts can appear more complex, with varying degrees of internal echoes. Usually, this appearance results from the presence of necrotic pancreatic and peripancreatic debris and is more common in pseudocysts that form as a result of acutenecrotizing pancreatitis than in other pseudocysts. The debris is cleared over time. The pseudocyst can appear more complex in 2 other instances: when hemorrhage occurs into the cyst or when infection of the cyst complicates the clinical course. Color Doppler or duplex scanning should always be performed in cystic lesions to ensure that the lesion in question is not a giant pseudoaneurysm.
