M.D., Ph.D. Author Information Division of Nuclear Medicine, University of Alabama Hospital, and V.A. Medical Center—Birmingham, Birmingham, Alabama Clinical Nuclear Medicine: March 1994 - Volume 19 - Issue 3 - p 236-237 Buy Abstract In-111 DTPA is a nondiffusable radiopharmaceutical, which, when introduced into the subarachnoid space, can be used to document flow patterns of cerebrospinal fluid (CSF) and also diagnose the site of CSF leakage with accurate localization. The authors describe a patient who developed drainage of clear fluid from the left external auditory canal, 1 month after left cochlear implant placement. The diagnosis of CSF otorrhea was easily confirmed by CSF cisternography. © Lippincott-Raven Publishers.
