Abstract:
Objective To study the value of CT and MRI(3D heavy T_2WI) in cerebrospinal fluid rhinorrhea.Methods 4 cases with spontaneous cerebrospinal fluid (CSF) rhinorrhea confirmed by operation were collected in this study.There were 2 men and 2 women.All patients underwent CT thickness was 0.625 mm and no gaps.MRI (coronal 3D heavy T2WI,thickness of 1 mm,TR/TE 5000 ms/119 ms).Results All 4 cases accepted the treatment of operations.The defects bone were showed by CT,and the sign of CSF of intracranial cavity communicated with nasal cavity diretly was showed by MRI,pituitary herniated into sphenoid sinus in one case also showed by MRI.Conclusion For spontaneous cerebrospinal fluid rhinorrhea,thin-section coronal CT scan and MR coronal 3D heavy T_2WI can clearly show the location of fistulas.
