Intracardiac hydatid cyst located in right ventricular outfl
Intracardiac hydatid cyst is relatively uncommon and involvement of right ventricular outflow tract is extremely rare. Authors report a rare case of intracardiac hydatid cyst involving the right ventricular outflow tract and do a review of literature.

A 46-year-old average built male, with no comorbidities, presented with occasional episodes of sudden hemoptysis over the last 4 years. During this period, he had intermittent cough with sputum, foul breath, and grade II dyspnea on exertion. He was initially seen by a local physician where he was suspected to have pulmonary tuberculosis. He received anti-tubercular medications for 6 months but the symptoms were not relieved.

Thereafter, he was referred to our institute. Computerized tomography (CT) of the thorax was done which showed a multiloculated cystic lesion in relation to the RVOT and multiple lung lesions suggestive of hydatid disease. Excision and marsupialization of the intracardiac cyst were performed and sent for histopathological examination. Histopathology showed the presence of acellular lamellated membranes of hydatid cyst with partially autolyzed brood capsules confirming the hydatid cyst.

The patient was discharged in stable condition after a few days and was prescribed oral albendazole 400 mg twice daily for 3 months. During close follow-up for 7 months, the patient was completely asymptomatic and did not have any episode of hemoptysis during or after surgery.
