Too many peas in the pod… encountering primary peritoneal hydatidosis in pregnancy: a rare mass in pregnancy.

Peritoneal hydatidosis, usually secondary to hepatic or splenic hydatidosis, is rarely primary and is reported even less with ongoing pregnancy. We present the case of a multiparous woman in her 30s, currently in the third trimester of pregnancy, presenting for routine screening, showing multiple cystic masses that were revealed to unexpectedly be a giant hydatid cyst on imaging evaluation as a part of the work-up for ovarian mass. Following spontaneous labour, an emergency caesarean section and exploratory laparotomy were performed, revealing over 400 cysts, which were confirmed as hydatid cysts through histopathological examination.Management of hydatidosis during pregnancy requires a combined medical and surgical approach. Our patient made a successful recovery, and both the mother and child were healthy. This case underscores the importance of early diagnosis through imaging and maintaining a high index of suspicion for systemic diseases that may complicate pregnancy.
