Ryall RG, Peacock MK, Simpson DA. double-ring sign (Figure 1B). Usefulness of beta 2-transferrin assay in the detection of cerebrospinal fluid leaks following head injury. The most rudimentary test is for a so-called double ring sign (Fig. May be # of temporal bone, may involve CN 7/8. 1969 Apr. [QxMD MEDLINE Link]. Predicting Fast Spinal CSF Leaks in Patients with Spontaneous intracranial Hypotension. Various other authors, including Dohlman (1948), Hirsch (1952), and Hallberg (1964), subsequently reported successful repair of CSF rhinorrhea through different external approaches. A variety of filter paper agents were used, including standard laboratory filter paper, paper towels, coffee filters, and bed linens. Traumatic leaks stop spontaneously in the majority of cases, thus a conservative approach is best. Ray BS, Bergland RM. There may be apparent downward displacement of the optic chiasm. Goel G, Ravishankar S, Jayakumar PN, et al. Mjovsk M, Grotenhuis A, Foroglou N, Zenga F, Froehlich S, Ringel F, Sampron N, Thomas N, Komarc M, Netuka D. Neurosurg Rev. 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. 110(7):1166-72. This dislocation allows CSF to flow to the opposite side and manifest at the contralateral naris. 2015 Apr 28. 1998 Apr. Careers. The typical history of a cerebropsinal fluid (CSF) leak is that of clear, watery discharge, usually unilateral. The .gov means its official. Apr 2012. Several surgical options for repair of CSF leaks arising from the anterior skull base exist. 2016 Nov. 6 (11):1126-30. Axial magnetic resonance cisternogram demonstrates the connection of the meningocele to the middle cranial fossa (arrows). All rights reserved. Image demonstrates increased tracer accumulation in the nasal region (arrow). Another advantage is the ability to more accurately position underlay or overlay grafts. Alternatively, radioactivity of the nasal pledgets is compared with that of known plasma radioactivity. This feature is the basis for a specific test for CSF based on immunoelectrophoresis. Bharucha T, Chanthongthip A, Phuangpanom S, Phonemixay O, Sengvilaipaseuth O, Vongsouvath M, Lee S, Newton PN, Dubot-Prs A. PLoS Negl Trop Dis. and transmitted securely. A halo pattern on a bedsheet produced by bloody otorrhea from a 27-year-old man who had been in a motor vehicle collision. In this experimental setting, the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid. Typically, 0.5 mL of a 10% fluorescein solution is injected into the lumbar subarachnoid space over more than 1 minute. Conservative treatment has been advocated in cases of immediate-onset CSF rhinorrhea following accidental trauma, given the high likelihood of spontaneous resolution of the leak. Digital subtraction radiographic cisternography can be similarly performed with a spinal subarachnoid injection of nonionic iodinated contrast medium. Cerebrospinal fluid rhinorrhoea in closed head injuries. (See images below.). Beta-2 transferrin is the most reliable confirmatory test for CSF leak. 2001 Jul. Follow-up 48- or 72-hour scans are possible with 111In and may be useful in the detection of intermittent CSF fluid leaks. 83(987):225-32. 92(5):873-6. The opposite is true for nontraumatic leaks, as only one third stop spontaneously. [QxMD MEDLINE Link]. The most common fracture sites leading to CSF leaks are the frontal sinus (30.8%), sphenoid sinus (11.430.8%), ethmoid (15.419.1%), cribriform plate (7.7%), frontoethmoid (7.7%), and sphenoethmoid (7.7%). Am J Rhinol Allergy. CSF is colorless, clear, and typically devoid of cells such as polymorphonuclear cells and mononuclear cells (< 5/L). Coronal and sagittal imaging is necessary. (Ann Emerg Med. NSF/NFD is a debilitating and sometimes fatal disease. 1994. A 58-year-Old non-smoking woman with intractable cough and rhinorrhea. [4], CT cisternography or radionuclide cisternography may be useful if CT and MR cisternography do not show the CSF fistula. 4th ed. A lumbar drain placed at the time of repair has not been shown to decrease recurrence of the CSF leak. Sagittal magnetic resonance cisternogram demonstrates the connection of the meningocele to the middle cranial fossa; this finding facilitated surgical planning. Matsumura A, Anno I, Kimura H, Ishikawa E, Nose T. Diagnosis of spontaneous intracranial hypotension by using magnetic resonance myelography. [1] The standard diagnostic test for temporal arteritis is biopsy; however, ultrasound and MRI show promise for replacing it. 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. Eljamel MS, Pidgeon CN, Toland J, et al. Herniation of the inferior frontal gyrus may occur in frontal head injuries or in ethmoid developmental defects of the cribriform plate. From the third ventricle, the fluid circulates into the forth ventricle and out into the subarachnoid space via the foramina of Magendie and Luschka. 2015 Feb. 23 (1):59-64. An official website of the United States government. encoded search term (Cerebrospinal Fluid Leak Imaging) and Cerebrospinal Fluid Leak Imaging, Plastic Surgery for Frontal Sinus Fractures, Plasma Biomarkers and Genetics in the Diagnosis and Prediction of Alzheimer's Disease. Spontaneous CSF rhinorrhea occurs in patients without antecedent causes. The .gov means its official. [QxMD MEDLINE Link]. Common sites of injury secondary to endoscopic sinus surgery include the lateral lamella of the cribriform plate and the posterior ethmoid roof near the anterior and medial sphenoid wall.

[11, 12, 5, 7, 13], Methods for detecting CSF fistulas with intrathecal injections of dye pose a risk of chemical meningitis. 8600 Rockville Pike It should be kept in mind, however, that this test does not provide information regarding the site or laterality of the defect. Once in contact with the paper, any CSF will separate from any blood or mucus. Lippincott Williams and Wilkins, Philadelphia 2000; Otolaryngol Clin North Am. Hence, educating the patient regarding the common symptoms associated with a CSF leak such as salty or metallic taste is of paramount importance. Endoscopic endonasal CSF rhinorrhea repair in children: Systematic review with meta-analysis. Spontaneous middle fossa encephalocele and cerebrospinal fluid leakage: diagnosis and management. Temporal lobe gyral herniation may occur through a petrous temporal bone tegmen tympani defect. MR T2 myelography may demonstrate spinal CSF fistulas (see the images below). 1-7. Drops of fluid from a CSF leak placed on absorbent filter paper may result in the double-ring sign, a central circle of blood and an outer clear ring of CSF. Other stresses include Valsalva-like maneuvers during nose blowing or straining. These cases often lead to a misdiagnosis of allergic and vasomotor rhinitis.

A small cribriform plate encephalocele is observed only after removing the middle turbinate. 2016 Jan. 206 (1):8-19. Any surgical manipulation near the skull base can result in an iatrogenic CSF leak. MR cisternography may demonstrate inactive CSF fistulas. [9].

Algin O, Hakyemez B, Gokalp G, Ozcan T, Korfali E, Parlak M. The contribution of 3D-CISS and contrast-enhanced MR cisternography in detecting cerebrospinal fluid leak in patients with rhinorrhoea. CSF consists of a mixture of water, electrolytes (Na+, K+, Mg2+, Ca2+, Cl-, and HCO3-), glucose (60-80% of blood glucose), amino acids, and various proteins (22-38 mg/dL). Typical imaging parameters include a repetition time of 10,000 ms, an effective echo time of 200 ms, 4 signals acquired, an echo train length of 16, a matrix of 512 X 192, no phase-wrap option, 3-mm sections interleaved contiguously (0-mm gap), and a 16-cm field of view.

Benedict PA, Connors JR, Timen MR, Bhatt N, Lebowitz RA, Pacione DR, Lieberman SM. If you log out, you will be required to enter your username and password the next time you visit. The embryologic defect is typically a patent fonticulus frontalis or foramen cecum. At this point, the dura herniates through the defect (meningocele). Penetrating and closed-head trauma are responsible for 90% of all cases of CSF leaks. The patient is maintained in the prone position until a CT scan is performed. [QxMD MEDLINE Link]. The resulting communication with the central nervous system (CNS) can result in a multitude of infectious complications that impart significant morbidity and potentially disastrous long-term deficits for the patient.
