Lieberman SM, Chen S, Jethanamest D, Casiano RR. CSF separates from blood when it is placed on filter paper, and it produces a clinically detectable sign: the ring sign, double-ring sign, or halo sign. -2 transferrin is a protein found in CSF, but not in serum, nasal secretions, or adjacent tissue. Ideally, the contrast medium is concentrated in the intracranial anterior and posterior skull base regions under fluoroscopic guidance by tilting the prone patient head downward on a fluoroscopic tilt table. Another technique, the injection of intrathecal fluorescein, has been used not only to diagnose CSF rhinorrhea but to localize the site(s) where it occurs. In-111 has minimal background activity and does not accumulate in the brain. Endoscopy may reveal an encephalocele or meningocele.

Disruption of the barriers between the sinonasal cavity and the anterior and middle cranial fossae is the underlying factor leading to the discharge of CSF into the nasal cavity. In one study of 45 patients, CT of the skull and facial bones with high-resolution, thin-section axial and coronal images had an accuracy of 92%, a sensitivity of 92%, and a specificity of 100% in depicting the presence or absence of CSF fistula. CT myelography is used in the detection of spinal CSF leak. Lawrence SK, Delbeke D, Partain CL. A positive diagnosis of CSF fistula is made by finding direct continuity of the CSF fistula with the subarachnoid space. For more information, see Medscape.
