Imaging Appearance of Enlarged Cisterna Chyli Mimicking Retroperitoneal Nodal Disease; A Rare Case Report

“…5 An enlarged cisterna chyli has been noted on CT and MRI scans in 1.7% and 15% of patients, respectively. 6 Multiple causes of an enlarged cisterna chyli include uncompensated cirrhosis, lymphangioleiomyomatosis, hypoalbuminemia, high central venous pressure, pancreatobiliary blockage, and lymphatic injury following earlier gastroesophageal or retroperitoneal surgery. Other causes mimicking an enlarged retroperitoneal node include an interrupted inferior vena cava with an azygos continuation and other venous malformations.…”
