Posttraumatic lumbar cerebrospinal fluid leak: detection by retrograde in-111-DTPA myeloscintography.

A case of lumbar cerebrospinal fluid (CSF) extravasation with an unsuspected traumatic meningocele after a gunshot wound was detected by means of retrograde myeloscintography using isobaric In-111-DTPA. Our experience and a review of the literature have provided evidence retrograde myeloscintography may be useful for detecting and delineating significant traumatic thoracic and lumbar CSF leaks.
