  • tc 99m dtpa Cisternography shows disappearance of cerebrospinal fluid leakage after standing a short time
    Clinical Nuclear Medicine, 2009
    Co-Authors: Del Mastro Carolina, Cicone Francesco, Dʼandrea Giancarlo, Scopinaro Francesco
    Abstract:

    Radionuclide Cisternography can demonstrate cerebrospinal fluid (CSF) leakage in some cases of the spontaneous intracranial hypotension syndrome. If symptoms do not disappear spontaneously after rest, epidural blood patching usually follows with good results. Cisternography often provides the only indirect signs of leakage with early bladder and/or slight cranial activity. We present a case of a 56-year-old man with a posterior thoracic CSF leak demonstrated by Tc-99m diethylenetriaminepentaacetic acid (DTPA) Cisternography. The extraspinal radioactivity was visible after the patient was supine for several hours and disappeared after a short time of standing, providing direct evidence of a CSF leak.

  • Cerebrospinal fluid fistula: detection with MR Cisternography.
    AJNR. American journal of neuroradiology, 1998
    Co-Authors: T El Gammal, W Sobol, V R Wadlington, Michael J. Sillers, C. E. Crews, Wink S. Fisher, Jeannette Y. Lee
    Abstract:

    PURPOSE Our goal was to assess the role of MR Cisternography in the examination of patients with suspected CSF rhinorrhea. METHODS MR Cisternography was performed as a heavily T2-weighted fast spin-echo study with fat suppression and video reversal of the images in 37 patients over a 3-year interval. Twenty-four of the patients subsequently had exploratory surgery for fistula. Statistical analysis of the surgical results was compared with the findings at MR Cisternography. RESULTS MR Cisternography showed significant correlation with surgical findings, with sensitivity, specificity, and accuracy of 0.87, 0.57, and 0.78, respectively. CONCLUSION MR Cisternography proved to be an accurate diagnostic imaging technique in the evaluation of suspected CSF rhinorrhea.

  • magnetic resonance Cisternography and thin coronal computerized tomography in the evaluation of cerebrospinal fluid rhinorrhea
    American Journal of Rhinology, 1997
    Co-Authors: Michael J. Sillers, Elliott C Morgan, Taher El Gammal
    Abstract:

    In recent years cerebrospinal fluid (CSF) rhinorrhea has been managed successfully with transnasal endoscopic techniques. The most important and often most difficult step is the precise localization of the fistula. Computerized tomographic and radionuclide Cisternography are two commonly used techniques for preoperative identification of the CSF fistula when it cannot be seen clearly with nasal endoscopy. Each of these requires a lumbar puncture, and the intrathecal placement of contrast material has been associated with transient neurotoxicities. Magnetic resonance Cisternography (MRC) is a noncontrast study that does not require a lumbar puncture and has been used recently in the diagnosis of spontaneous and traumatic CSF leaks. Magnetic resonance Cisternography utilizes a fast spin-echo sequence with fat suppression and video image reversal that highlights CSF. This allows precise localization of the fistula in both coronal and sagittal planes. Thin section coronal computed tomography (TCCT) is another noninvasive technique that can be helpful in localizing CSF leaks. The technique of MRC and TCCT and the results of 16 CSF leaks in 15 patients are reported. There was good correlation between MRC, TCCT, and intraoperative findings. Magnetic resonance Cisternography and thin coronal computerized tomography appear to be accurate and complementary, noninvasive radiographic studies that should be considered in the evaluation CSF rhinorrhea.
