Successful treatment of hydatid cyst of lesser sac with PAIR therapy.

Hydatid disease has varied presentations and may involve any part of the body with hydatid disease of the liver being the most common site. Hydatid disease of lesser sac is a rare entity. Different treatment options of hydatid liver disease are available which include surgical, medical and radiological management. Surgical management has its limitations in terms of cost, morbidity, mortality, rate of recurrence and patient fitness to undergo surgery. Medical management alone carries a low chance of cure. Radiological management with PAIR therapy (percutaneous aspiration, injection and re-aspiration) of hydatid liver disease has been well described in literature. However, hydatid disease of lesser sac in itself is a rare entity and its treatment with PAIR procedure has not been described before. We describe a case of hydatid disease of lesser sac treated with the PAIR procedure.
