Abstract

She developed itching prior to the hospital visit. 40 years old male presented with abdominal swelling since 1 year, not associated with vomiting or jaundice. Both the patients were from rural background. Conclusion. Echinococcus granulosus can cause cystic lesions anywhere in the body. High degree of suspicion of hydatid disease is essential in endemic areas in cystic lesions.
