[Diseases of the diaphragmatic area. Difficulties of the radiological diagnosis].

Following a reminder of anatomy, the semiology of standard radiology and modern imaging methods is described. The authors then deal with the phrenic-supraphrenic thoracic pathologies (air and liquid effusions, neighbourhood atelectasis, etc.) and with the phrenic-infraphrenic pathologies (transdiaphragmatic hernias, hepatic pathology, subphrenic abscess and pleural effusions). In each of these chapters, the often complex elements of standard radiology and modern imaging methods are detailed.
