A 32 year-old patient has a bi-ventricular insufficiency that had developed over the past 2 months revealed by cardiac symptomatology. Echocardiography revealed bi-ventricular dilated cardiomyopathy. He had skin lesions for three years that were clinically and histologically identified as psoriasis. The association of cardiomyopathy with psoriasis is rare and intriguing and the link between these two entities on a common inflammatory background is discussed.

Isolated cardiac location is an uncommon presentation of echinococcus (0.2-3%), and involvement of the interventricular septum is even rarer. it may conduct to life-threatening complicationsincluding cyst rupture; anaphylactic shock; tamponade; pulmonary, cerebral or peripheral arterial embolism; acute coronary syndrome; dysrhythmias; infection; ventricular or valvular dysfunction, as well as sudden death. The diagnosis is based on a range of arguments, here we report the case of a 15years old girl who was diagnosed to have a hydatid cyst of the interventricular septum , the presentation, management and follow-up of the patient is discussed.
