[Postoperative abscesses and empyemas. Apropos of 13 cases]

13 cases of severe intracranial postoperative infections, abscesses and/or empyema, are reported. These lesions, whose clinical diagnosis is often difficult, have benefited from C.T. scan. The diffusion of the infectious process in operatory focus, the frequency of Staphylococcal origin and the importance of high doses antibiotherapy must be underlined. This one is, of course, an indispensable complement to reintervention, but it may be utilized alone with success in selected cases, or insure the definitive cure when reintervention is partial.
