Disseminated hydatid cyst of liver and lung

Hydatid cyst commonly affects liver followed by lung, but rarely affects both organs simultaneously. Here we presented a patient who presented with concurrent involvement of both lungs and liver. Patient presented with dyspnoea and generalised weakness with bilateral rounded opacities throughout the lung field of variable sizes. CT scan chest with contrast showed multiple rounded soft tissue density in both lungs and liver. Patient underwent mini thoracotomy which revealed multiple cystic lesions throughout lung. ELISA for anti-Echinococcus antibodies shows positive titres. Due to extensive involvement, patient was started on medical treatment albendazole. The patient showed significant improvement both clinically and radiographically on treatment. Thus long-term medical treatment helps in such cases where surgery is not possible.
