On examination, her vitals were within normal limits; per abdominal examination revealed 7\u00d77\u2009cm mass in the right lumbar and right hypochondrium with well-defined margins. A Contrast-enhanced whole abdomen done showed a thin-walled of cyst of size 7\u00d78\u00d79 cm in the right lumbar region abutting and replacing the mesenteric border of ascending colon suggesting of mesenteric cyst.
