However, an astute clinician noted the double ring sign on the stretcher sheet, as noted in the Figure 1. Management and Disposition Identify underlying brain injury, which is best accomplished by CT. CT is also the best diagnostic tool for identifying the fracture site, but fractures may not always be evident. Cappabianca P, Cavallo LM, Esposito F, et al. A short repetition time can be used to achieve a result similar to that of the technique above, with slightly faster imaging times. In this experimental setting, the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid. The dura of the anterior cranial base is subject to wide variations in CSF pressure because of several factors, including normal arterial and respiratory fluctuations. A 58-year-Old non-smoking woman with intractable cough and rhinorrhea. The high T2 signal from CSF fistula may be difficult to differentiate from that of sinusitis on axial images. The brain is noted to sink downward in the cranium with development of a pseudo-Chiari I malformation. In radiology, the halo sign is a finding of a dark halo around the arterial lumen on ultrasound that suggests the diagnosis of temporal arteritis. No double ring sign was identied using this test. 2014 Sep. 59 (2):196-9. Study objective: Medicina (Kaunas). [10]. The .gov means its official.

However, the presence of a ring sign is not exclusive to CSF and can lead to false-positive results. One drop of blood and one drop of either spinal fluid, saline, tap water, or rhinorrhea fluid were placed simultaneously on filter paper, and the specimens were examined after ten minutes for the development of a ring. On occasion, the methods listed above do not localize the CSF fistula, and surgical exploration may be necessary. CSF represents the end product of the ultrafiltration of plasma across epithelial cells in the choroid plexus lining the ventricles of the brain. 4:CD004884.

The typical history of a cerebropsinal fluid (CSF) leak is that of clear, watery discharge, usually unilateral. Circulation of CSF is maintained by the hydrostatic differences between its rate of production and its rate of absorption. A variety of filter paper agents were used, including standard laboratory filter paper, paper towels, coffee filters, and bed linens. Ann Nucl Med. Several texts have suggested that CSF will separate from blood when the mixture is placed on filter paper or other media and will produce a clinically detectable sign, which has been referred to as a ring sign, double ring sign, or halo sign. Case report. 2015 Jan-Feb. 29 (1):77-81. Spontaneous CSF rhinorrhea usually manifests in adulthood, coinciding with a developmental rise in CSF pressure with maturity. The patient had no Battle sign (i.e., bruising over the mastoid process). When there is doubt about the origin of the blood, the diagnosis of a basilar skull fracture must be excluded. 2000 Jul.

Another advantage is the ability to more accurately position underlay or overlay grafts. In a study of 4 patients who underwent radionuclide cisternography, as well as MRI and/or CT, for suspected CSF leaks, Thomas et al found that radionuclide cisternography accurately detected and localized the leaks in all patients. Spinal MRI findings are also potentially reversible after successful ablation of a CSF fistula. However, most of the time physical examination is unrevealing, especially in patients with intermittent CSF rhinorrhea. A doctor can use a number of tests to diagnose a CSF leak. For example, anosmia (present in 60% of individuals with post-traumatic rhinorrhea), indicates an injury in the olfactory area and anterior fossa, especially when it is unilateral.

By the same principles as those applied in planar chromatography, the drainage of bloody discharge onto the patient's pillow or a paper towel can be seen to . Imaging findings were correlated with both the clinical findings and nasal pledget counts obtained as part of this study. Neuroradiology. The natural history of CSF rhinorrhea is highly dependent on the underlying etiology. Nuclear cisternogram obtained at 24 hours demonstrates diffuse epidural accumulation of the tracer in the midlumbar region. Cerebrospinal fluid rhinorrhoea in closed head injuries. The type of filter paper did not affect the development of a ring. In patients with nonsurgical trauma, waiting a period of 5-7 days to allow conservative measures (bed rest, stool softeners, and lumbar drainage) to assist with secondary closure of the traumatic defect is reasonable. Since then, endoscopic repair has become the preferred method of addressing CSF rhinorrhea, given the high success rate of 90-95% and the decreased morbidity associated with this approach.

The image demonstrates dense contrast medium layering in the empty sella and contained within the meningocele (arrow). The cerebral ventricles may be reduced in size, and the pituitary gland may appear enlarged. This dislocation allows CSF to flow to the opposite side and manifest at the contralateral naris. There are several causes of elevated ICP; however, the proposed mechanism underlying spontaneous CSF rhinorrhea is idiopathic intracranial hypertension (IIH). [QxMD MEDLINE Link]. A positive diagnosis of CSF fistula is made by finding direct continuity of the CSF fistula with the subarachnoid space. 2015 Feb. 23 (1):59-64. In patients with head trauma, a mixture of blood and CSF may make the diagnosis difficult. (Ann Emerg Med. 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.
