Lumbar spine intracanalicular discal cysts: two case reports.

The only previously reported series of lumbar intracanalicular discal cysts, which were termed intervertebral discal cysts, described Asian male involvement with verification of diagnosis via discography (1). Two cases are presented in non-Asian males under the age of 21 years, one of which was diagnosed preoperatively by MRI scan. Both patients did well with microsurgical intervention.
