Breast Hydatid Cyst: Diagnosis and Treatment of a Rare Case with Spontaneous Rupture.

Background

Hydatid cysts, caused by Echinococcus granulosus, are uncommon in the breast but are observed in endemic regions of the Eastern Mediterranean. This study evaluates the diagnosis and treatment of this rare occurrence of breast hydatid cyst and its spontaneous rupture. Case Presentation: A 33-year-old female patient presented to our clinic with a mass in the right breast that had been growing for 9 months and causing intermittent pain. Physical examination revealed a well-defined, firm mass with regular borders and some soft areas. Ultrasonography reported a complicated cyst(?). While awaiting the report of breast magnetic resonance imaging, the patient returned to the hospital because of the discharge of white material from the breast. Examination revealed a laminar membrane from the perforated area. Under sedation, the cyst was evacuated, vesicles were removed, and the cyst cavity was irrigated with 3% saline for drainage.

Conclusions

Although breast hydatid cyst is rare, it should be considered in the differential diagnosis, especially in endemic regions. Magnetic resonance imaging and drainage, combined with prophylactic albendazole, represent a safe and effective diagnostic and treatment approach.
