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.
