Isolated pelvic type 1 cystic echinococcosis is a rare form of the disease with diagnostic pitfalls mainly based on non-diagnostic imaging findings. CASE REPORT: We present an isolated pelvic cystic echinococcosis resembling ovarian tumor which was diagnosed during operation. CONCLUSIONS: Characteristic findings of hydatid disease lacks in type 1 and cause diagnostic difficulties. This rare entity should be considered for differential diagnosis due to varied examination findings especially in type 1 cystic echinococcosis.
