[Right partial diaphragmatic eventration. Diagnostic and therapeutic aspects]

The Authors report a case of asymptomatic right partial diaphragmatic eventration, casually discovered and surgically repaired by imbrication of the hemidiaphragm. They confirm the almost completely asymptomatic and benign character of this disease, and discuss the difficulty of the differential diagnosis with various diseases of the right cardiophrenic angle, particularly the pericardial cysts. Among the diagnostic techniques the Authors advocate the priority of the liver scanning, the echotomography, the C.A.T., the pneumoperitoneography and, in case, the celiac axis arteriography. They consider the plastic repair of the diaphragm performed by a thoracic approach to be indispensable to the confirmation of the diagnosis and, of course, to a radical therapy.
