A hydatid cyst of the heart is rare. Surgical treatment is the preferable method in the treatment of cardiac echinococcosis. A 27-year-old patient with right ventricular hydatid cyst causing recurrent pulmonary emboli and diagnosed by 2-dimensional echocardiography and treated surgically is presented.

Castleman's disease is often referred to as giant lymph-node hyperplasia. Although this localized disorder most commonly involves the mediastinum, recently many patients have been described with multicentric lymph-node hyperplasia associated with various clinical abnormalities. Here a new case of multicentric angiofollicular lymph-node hyperplasia associated with myasthenia gravis and gammopath y is presented. At first, the patient respond ed to surgery well, but after some months her condition deteriorated: plasmapheresi s was then performed, one year after the operation, with great clinical improvement.

A cas e of sponta neous coronary artery dissection in a 26-yearold male with subsequent left-ven tricular ane urysm is reported. A coronary bypa ss operatio n using left intern a l mamma ry artery combined with left-ventricul ar an eurysme ctomy was performed successfully. This is the youngest cas e in the literature which describes a successful surg ical treatment for a spontaneous corona ry artery dissection with left-ventricular aneurysm .

Aneurysmal dilatation of coronary arteries is characterized by abnormal dilatation of a localized or diffuse segment of the coronary arterial tree. Left main coronary artery aneurysms are rare coronary anatomic abnormalities. They rarely involve the left main coronary artery. Different strategies have been adopted, where the coronary artery aneurysms have been left as such, resected partially, isolated, reconstructed, ligated with a simultaneous bypass with internal mammary artery, or treated with vein grafts. We report a case of a successful ligation of aneurysm of the left main coronary artery and three simultaneous coronary artery bypass procedures (Fig. 1, Ref. 15).
