Abstract

We aimed to present CT findings of spontaneously ruptured liver cyst hydatid with wandering intraabdominal daughter cyst. We present the case of a 39-year-old woman who presented with abdominal pain. An exophytic cystic mass in the liver was detected in the assessment of patient with sonography. On CT examination an unenhanced, exophytic, thin walled hypodens cystic mass (measured 8 cm) originating from segment III was diagnosed as cyst hydatid and follow-up recommended. Two weeks later, she was admitted to CT examination after experiencing acute abdominal pain. CT revealed that the liver cystic mass disappeared and another cystic mass with similar measurements with previous cyst occupying pelvis with minimal intraperitoneal free fluid. The diagnosis of ruptured cyst hydatid with wandering intraperitoneal doughter vesicle was made. Surgery confirmed our imaging findings. This unusual condition highlights the need for radiological follow-up of cyst hydatid as a potential cause of acute abdominal pain.
