Case presentation:
A nine-year-old girl from northern province in Syria, presented to our hospital with recent developing exertional dyspnea. In her past medical history, she had undergone surgical resection of liver hydatid cysts four years ago. TTE showed a 50 × 55 mm heterogeneous cystic mass localized in the free wall of the right ventricle outlet (figure 1). Routine laboratory tests were normal. Depending on TTE findings, the patient’s demographic origin, and her surgical history, the diagnosis of right ventricle hydatid cyst was established. After a 5-day oral Albendazole course, surgery was performed through median sternotomy, and cardiopulmonary bypass (CPB) was prepared. The cyst was apparent within the wall of the right ventricle outlet (figure 2). The operating field was isolated by medical gauze saturated with hypertonic saline solution. Without arresting the heart, a small incision on right ventricular outlet was carried out. The contents of the cyst were aspirated, and the cyst cavity was injected with 30% saline solution. Then the cyst was dissected and enucleated (Figure 3). The patient recovered without complications, and was discharged home six days later on albendazole for 12 weeks.
