Surgical treatment of a sacral nerve root cyst with intermittent claudication in an 85-year-old patient: case report.

The following presents a case of an 85-year-old woman with intermittent claudication of a sacral nerve root cyst. The cyst wall was incised and oversewn while preserving the surrounding nerve fibers by microscopic procedures. All symptoms were eliminated following the operation. The syndrome of intermittent claudication may possibly arise while walking from the transient influx of cerebrospinal fluid into a cyst in a relatively narrow sacral canal. The present case may indicate that a sacral nerve root cyst is curable even in aged patients through thorough evaluation and management.
