Surgical repair of spontaneous cerebrospinal fluid (CSF) leaks: A systematic review. It is produced in epithelial cells of the choroid plexus and meninges and is found in CSF, perilymph, seminal fluid, and urine. This article discusses current concepts in the etiology, diagnosis, and treatment of CSF rhinorrhea, as well as long-term management of patients following successful treatment. Spinal MRI findings are also potentially reversible after successful ablation of a CSF fistula. Skull Base Fracture - an overview | ScienceDirect Topics 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. He had been wearing a seat belt. [QxMD MEDLINE Link]. Radionuclide cisternography is performed by administering a lumbar subarachnoid intrathecal injection of Indium-111 (111In) diethylenetriamine pentaacetic acid (DTPA) in a 500 Ci dose. Delayed fistulas are difficult to diagnose and can occur years after the trauma or operation. Double-ring sign in granulocyte colony-stimulating factor-induced However, if CSF rhinorrhea persists beyond this point, or if a large skull base defect is observed at the time of injury, surgical repair is warranted. Spelle L, Boulin A, Tainturier C, Visot A, Graveleau P, Pierot L. Neuroimaging features of spontaneous intracranial hypotension. The test for CSF fluid involves placing a sample of what the doctor suspects to be CSF discharge on a piece of filter paper. Hence, the surgical team should be prepared to repair the resulting CSF leak at the time of the resection, either transcranially or endoscopically. Diagnosis of cerebrospinal fluid rhinorrhea: an evidence-based review with recommendations. The role of MR myelography with intrathecal gadolinium in localization of spinal CSF leaks in patients with spontaneous intracranial hypotension. Nuclear cisternogram obtained at 24 hours demonstrates diffuse epidural accumulation of the tracer in the midlumbar region. The ring is a result of the different densities of blood and CSF, and is concerning for a basilar skull fracture., While the presence of a double ring sign (sometimes called a halo sign) is often cited as indicating the presence of CSF (Sapira's Art and Science of Bedside Diagnosis. Chiapparini L, Farina L, D'Incerti L, et al. Spinal radiological findings in nine patients with spontaneous intracranial hypotension.
