Dilemma of the giant abdominal cyst.

Giant abdominal cyst can lead to various non-specific symptoms such as abdominal bloating, nausea/vomiting, constipation due to its mass effect. In rarer circumstances, it can lead to bowel obstruction, hydronephrosis and even abdominal compartment syndrome. Hereby, we present a case of giant abdominal cyst in a young woman where its origin was a diagnostic dilemma despite exhausting all imaging techniques. A laparotomy was performed and the giant cyst was found to be originating from the left ovary. The final histopathology confirmed it as an ovarian benign serous cystadenoma. The patient made a fully recovery without any complications.
