[Pelvic hydatid cyst and pregnancy. Four cases]

Area of Science:

• Obstetrics and Gynecology
• Parasitology
• Infectious Diseases

Background:

• Pelvic hydatid cyst (PHC) is a rare condition, especially during pregnancy.
• Hydatid disease is caused by the tapeworm Echinococcus granulosus.

Observation:

• A retrospective study identified 4 cases of PHC associated with pregnancy between 1981-1990.
• The incidence was estimated at 1 per 30,000 deliveries.
• Diagnosis was suspected based on geographic origin and prior extra-pelvic hydatid disease history.

Findings:

• Ultrasonography was the primary diagnostic tool, confirming the presence of pelvic hydatid cysts.
• In three pregnancies that reached term, no significant changes were observed in the cysts.
• One patient successfully underwent vaginal delivery twice, despite literature reporting potential complications.

Implications:

• The rarity of this association necessitates careful consideration of diagnostic and management strategies.
• Optimal timing for surgical intervention and mode of delivery require further discussion due to potential risks.
• Early diagnosis and management are crucial for favorable maternal and fetal outcomes in cases of pelvic hydatid cyst during pregnancy.
