[7], Brain and spinal MRI is useful in demonstrating meningocele and meningoencephalocele when associated with CSF leak, as well as for examining patients with spontaneous intracranial hypotension syndrome. Rapid echo-planar imaging with the patient in the prone position and performing a Valsalva maneuver may allow for limited coronal imaging and increase the accuracy of MR cisternography. PMC Free shipping for many products! Iatrogenic CSF rhinorrhea results from surgical disruption of the skull base and dura as previously discussed. We reviewed 68 studies examining 9 practices pertinent to the diagnosis of CSF rhinorrhea, with a highest aggregate grade of evidence of C. The literature does not support the use of the ring sign, glucose testing, radionuclide cisternography (RNC), or computed tomography cisternography (CTC) for identification of CSF leak. 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. Study objective: Unauthorized use of these marks is strictly prohibited. A systematic review of the literature was performed using PubMed, EMBASE, and Cochrane databases from January 1990 through September 2014, to examine 9 diagnostic and localization modalities for CSF rhinorrhea.

Ann Emerg Med. In patients undergoing endoscopic sinus surgery, the site of injury is most frequently the lateral lamella of the cribriform plate, where the bone of the anterior skull base is thinnest. A variety of cisternographic studies may be necessary to localize some spinal CSF fistulas. If an iatrogenic leak is detected intraoperatively, it should be repaired at the time of the original surgery. The gray scale is reversed for optimal viewing.

This terminology seems to imply that spontaneous CSF leaks are idiopathic in nature; however, recent evidence has led us to realize that spontaneous CSF rhinorrhea may in reality be secondary to an intracranial process, namely elevated intracranial pressure (ICP). Magnetic resonance cisternography (MRC) should be used for CSF leak identification as a second line for each of these if beta-2 transferrin is not available or if HRCT is ambiguous. Additional hardware or software is not required to perform MR myelography or cisternography. [29]. 1994 Nov. 111(5):600-5.

A short repetition time can be used to achieve a result similar to that of the technique above, with slightly faster imaging times. On occasion, the patient has a history of headache relieved by drainage of CSF. Diagnostic strategies employed for cases of cerebrospinal fluid (CSF) rhinorrhea vary widely due to limited evidence-based guidance. The use of topical intranasal fluorescein in endoscopic endonasal repair of cerebrospinal fluid rhinorrhea. [QxMD MEDLINE Link]. However, an astute clinician noted the double ring sign on the stretcher sheet, as noted in the Figure 1. The specificity is almost 100% for contemporary radionuclide cisternography. The type of filter paper did not affect the development of a ring. CT cisternographic findings in CSF leak include the concentration of contrast medium in portions of a paranasal sinus or within ethmoid or mastoid air cells. [QxMD MEDLINE Link].
