If persistent fluid drainage occurs after a fracture, the fluid may be evaluated to test for the presence of CSF. Cerebrospinal fluid (CSF) leaks are generally classified as traumatic, iatrogenic, and spontaneous/idiopathic. Observe with a Wood lamp 30 minutes later for fluorescence of nasal discharge; if present, this confirms CSF . 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.

According to another theory, the tear and bony defect are present from the time of the original injury, but the leak occurs only after the masking hematoma dissolves. To study the development of a ring sign when blood is mixed with various fluids. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. From the third ventricle, the fluid circulates into the forth ventricle and out into the subarachnoid space via the foramina of Magendie and Luschka. Cerebrospinal fluid (CSF) is a clear fluid that surrounds your brain and spinal cord. NSF/NFD has occurred in patients with moderate to end-stage renal disease who have been given a gadolinium-based contrast agent to enhance MRI or MRA scans. Akbar JJ, Luetmer PH, Schwartz KM, Hunt CH, Diehn FE, Eckel LJ. After intrathecal fluorescein is administered, an exposed frontal recess encephalocele is seen. The specificity is almost 100% for contemporary radionuclide cisternography. The .gov means its official.
