Background The ductus arteriosus, an essential fetal structure, normally closes spontaneously soon after birth. It’s persistence into late adulthood is considered rare; infective endarteritis complicating a patent ductus arteriosus (PDA) is an even rarer event. The clinical picture of an infected PDA could be subtle, and the diagnosis is frequently delayed. Case presentation We present the case of a young women who presented with prolonged fever, in whom we made the diagnosis of a patent ductus arteriosus complicated by infective endarteritis with vegetations in both pulmonary and aortic wall with mycotic aneurysms of the descending aorta. She underwent surgery and postoperative course was uneventful. Conclusion To our knowledge, this is the first reported case of a patent ductus arteriosus complicated with both pulmonary and aortic endarteritis.

Background Cardiac hydatid cyst is a rare parasitic disease. Since it may be associated with fatal complications, early diagnosis and treatment of a cardiac hydatid cyst is very important, however, it may stay asymptomatic for a long time, until they reveal themselves being perforated into cardiac chambers and/or pulmonary artery or systemic circulation. Case presentation: We report a case of a young asymptomatic boy, who underwent a routine chest x ray in a pre employment check up in whom we discovered a multiple pulmonary lesions and a right ventricle hydatid cyst. He then underwent a successful treatment Conclusion Due to the high risk of associated complications, cardiac hydatid cysts should be removed surgically, even in asymptomatic patients.
