Leptomeningeal cysts associated with traumatic cerebrospinal fluid rhinorrhea

Abstract

✓ Nine instances of traumatic leptomeningeal cysts associated with rhinorrhea are described. The authors believe that the consequences of head trauma are responsible for both the rhinorrhea and the formation of leptomeningeal cysts, and that the scintigraphic demonstration of a leptomeningeal cyst may help in diagnosis when no overt rhinorrhea is present.
