Massive Retroperitoneal Cyst during Pregnancy: Case Report Managed Conservatively by Percutaneous Aspiration and Review of Literature

“…4 There were 2 cases (28.6%) that had expectant management through the pregnancy and underwent postpartum laparotomy to remove the cyst. 2,6 Both cases were relatively smaller cysts among the reported cases (largest diameters 11.7 and 10 cm, respectively).…”

“…There were two cases of expectant management throughout the pregnancy. 2,6 Neither patient developed any complication associated with the cyst or prenatal complication. The cysts did not change in size and were relatively smaller (11.7 cm and 10 cm, respectively).…”

“…Retroperitoneal cyst during pregnancy can occur at any gestational stage. 1,2,[4][5][6][7] The cysts were generally massive but rarely changed in size. Various pathologies of retroperitoneal cyst included lymphocele, 5 hemorrhage into cyst, 5 and chronic inflammation.…”

“…Although ultrasonography was used in many cases (71.4%), literature supports the use of MRI to diagnose the retroperitoneal cyst during pregnancy and gives precise information of the origin of organ and characteristics of cyst. 2,6,8 Ultrasonography could be a useful tool to follow the cyst size after the initial evaluation with MRI.…”
