Abstract
INTRODUCTION: Hydatid cyst (HC) disease is a serious health problem in endemic areas. It is a parasitic infection that commonly involves liver and lungs while muscular HC is rare. HC of abdominal wall was reported only six times. We reported a 39-year-old male presented with HC of the right loin who was managed surgically with brief literature review. CONCLUSION: HC should be put in the differential diagnosis of the abdominal wall masses. Its pre-operative diagnosis is important to prevent rupture with subsequent anaphylaxis and recurrence. Surgery is the main modality of treatment.
