[Computer tomographic and sonographic diagnosis of diaphragmatic hernias]

The diagnosis of supra diaphragmatic masses, particularly Morgagni's, Larrey's or Bochdalek's hernia was rarely possible by conventional methods. By using sonography and, more particularly, computed tomography, these hernias can be distinguished from other masses in the region of the diaphragms. Their characteristic appearances and the diagnostic procedures are described. Invasive procedures, such as diagnostic pneumoperitoneum, are no longer necessary.
