Abstract
Objective To evaluate the value of CT and CTC in the patients with post traumatic CSF rhinorrhea. Methods Coronal imaging of CT and CTC in 18 patients with post traumatic CSF rhinorrhea were observed and analyzed by two experienced neuroradiologists. Results On conventional CT imaging,all the patients shown bone change of skull base,which is,included fracture and cranial defect in one or multiple place.CTC correctly showed the sites of CSF leakage in 16 of 18 cases proved surgically.Single fracture or cranial defect was seen in 13 cases.The CSF leakage,which is seen on CTC,was shown in the same position of bone change.Compound fracture was seen in 5 cases.Two sites of leakage were shown on CTC imaging in 2 of 5 cases.In another three cases only one site was seen. Conclusion CTC is an effective method for locating the site of the CSF leakage. [
