Primary and Solitary Uterine Hydatid Cyst: A Most Unusual Site

An unmarried, but not a virgin, woman aged 28 years, suffered from menorrhagia for a few months. She was diagnosed by several gynecologists and sonologists to be suffering from hydatidiform mole. She was diagnosed as a case of hydatid cyst in uterus only by ultrasound scan. There was a 12-cm-diameter cyst inside the uterus with innumerous daughter cysts. Echinococcus antibody test was performed, which confirmed the diagnosis of hydatid cyst. Serum β-human chorionic gonadotrophin was done, and the result was negative. Computed tomography scan of the whole body did not detect any other cyst. A rare case of primary and solitary hydatid cyst in the uterus is reported here, which was diagnosed preoperatively by ultrasonography. Symptoms are often absent, and in many cases, it is detected incidentally, but in this instance, the patient suffered from menorrhagia. A team of surgeons and gynecologists first drained the fluid and then removed the cyst wall. The location of hydatid cyst in the genital tract is rare, and its presence in the uterus is extremely rare. A careful sonographic examination of the pelvic masses should be carried out to avoid wrong diagnosis as accurate preoperative detection is very essential for the patient’s well-being.
