[CT cisternography in the diagnosis of nasal cerebrospinal fluid fistulas].
Four out of 12 patients with CT-cisternography were operated on. The CT findings were all confirmed at operation. In three patients with positive CT findings, the fistula was located at operation. In one case with negative CT findings, operation revealed no fistula either. Advantages of CT-cisternography are reliability of positive findings and the possibility of locating the fistula in some cases. The procedure bears relatively little risk and can be repeated.
