Gallbladder schistosomiasis, caused by Schistosoma mansoni, is rare. Microscopic examination confirmed parasitic eggs in a patient presenting with a gallbladder lesion, highlighting the need for vigilance in endemic regions.
Area of Science:
- Parasitology
- Hepatology
- Gastroenterology
Background:
- Schistosomiasis is a neglected tropical disease caused by Schistosoma flatworms.
- While hepatosplenic involvement is common, gallbladder schistosomiasis is exceptionally rare.
- This case addresses a unique presentation of Schistosoma mansoni infection.
Observation:
- A patient from an endemic area presented with gallbladder wall thickening and a solid lesion.
- Laparoscopic cholecystectomy was performed uneventfully.
- Histopathological analysis revealed Schistosoma mansoni eggs and a granulomatous response.
Findings:
- The gallbladder lesion was definitively diagnosed as schistosomiasis.
- Microscopic examination is crucial to differentiate from malignancy.
- Praziquantel treatment and follow-up were initiated.
Implications:
- This case underscores the importance of considering schistosomiasis in differential diagnoses for gallbladder lesions in endemic areas.
- Early diagnosis and treatment are essential to prevent complications.
- Further case reporting is needed to better characterize gallbladder schistosomiasis management.
