[Primary Pelvic Cystic Echinococcosis]

Area of Science:

• Parasitology
• Medical Imaging
• Surgical Pathology

Background:

• Cystic echinococcosis (CE), caused by Echinococcus granulosus, is a significant public health concern in endemic regions.
• CE commonly affects the liver and lungs, with pelvic involvement being exceptionally rare and often secondary to other organ infestations.

Observation:

• This case report details a patient presenting with a pelvic cystic mass.
• Initial assessments did not strongly suggest a parasitic etiology for the pelvic mass.

Findings:

• Post-operative pathological examination confirmed the diagnosis of isolated pelvic cystic echinococcosis.
• The patient's pelvic cystic mass was definitively identified as Echinococcus granulosus infection.

Implications:

• This case underscores the importance of considering cystic echinococcosis in the differential diagnosis of unexplained pelvic masses, even in the absence of typical organ involvement.
• Raising awareness among clinicians can improve diagnostic accuracy and timely management of rare presentations of this parasitic disease.
