Primary Hydatid Cyst of Neck, A Rare Case Report

Hydatid cyst is a result of parasite infection. The neck is an uncommon site for this infection so it is not considered as a differential diagnosis of neck swelling commonly. We hereby report a case of 24 year female with left postero-lateral neck swelling for 5 years that was insidious in onset and gradually increased in size. We diagnosed the case as hydatid cyst of neck on FNAC and MRI. Pre operatively oral albendazole was given for 1 month and continued post operatively. Our case has not shown recurrence for 6 months after successful surgical excision. So primary hydatid cyst should be considered as a differential diagnosis of neck swelling and should be treated accordingly.
