Lung Hydatidosis Unveiled: A Multisystem Mirage of Pathological Rarity

Lung hydatidosis is a zoonotic infection, primarily caused by Echinococcus sp., and has a significant role in the economy and public health. Canines are the predominant hosts of these parasitic tapeworms. Lungs are the most commonly infected organ after the liver. Hepatic pulmonary blood circulation is mainly reported to transport infection to the lungs. The prevalence of hydatid disease has increased over the past decade. In addition, patients with multi-organ involvement of hydatid cysts have been reported in different parts of the world. Hydatidosis can remain asymptomatic for years after infection in some conditions, especially in cases of splenic hydatidosis. Chest radiography and computed tomography findings can be used to confirm the diagnosis of hydatid disease. Hydatid disease is, in general, managed by pharmacological therapy, but if multi-organ involvement is observed, surgery along with medical management is required. Long-term follow-up is recommended in such cases to check the recurrence of the disease.
