[Value of computed tomography in the diagnosis of fistulas].
OBJECTIVE
The purpose of the study was to determine the value of computed tomography (CT) in demonstrating fistulae in comparison with conventional radiographic methods.


METHODS
In a prospective study 25 patients were evaluated by conventional radiographic methods and CT.


RESULTS
The identification of the fistulous tract was possible with CT in 27 of 29 cases, whereas 2 fistulae could only be detected by indirect signs. Furthermore, CT showed a larger extent of the fistulous tract in 5 patients and revealed complications such as inflammatory mass, abscess or osteomyelitis in 11 cases.


CONCLUSIONS
CT seems to be superior in demonstrating the extent of a fistulous tract and provides valuable information on the surrounding structures.
