Successful treatment of a symptomatic L5/S1 discal cyst by percutaneous CT-guided aspiration

BACKGROUND: Discal cysts are a rare cause of lumbar radiculopathy. Benefits of percutaneous computed tomography (CT)-guided aspiration of the cyst include decreased rate of infection, avoidance of general anesthesia, and quicker recovery.

Sumario:BACKGROUND: Discal cysts are a rare cause of lumbar radiculopathy. Benefits of percutaneous computed tomography (CT)-guided aspiration of the cyst include decreased rate of infection, avoidance of general anesthesia, and quicker recovery. However, since the publication of a case of cyst recurrence after CT-guided aspiration, few have utilized this potentially valuable technique. CASE DESCRIPTION: We present a patient with a discal cyst arising from the L5/S1 disc causing right S1 radiculopathy. He underwent percutaneous CT-guided aspiration with substantial improvement in his radicular pain with 19 months of follow-up. His improvement was measured quantitatively using the Japanese Orthopedic Association scale: 6/15 pre-procedure, 15/15 post-procedure. CONCLUSION: Percutaneous CT-guided aspiration of discal cysts may be a valid initial treatment option for this condition. Patients who do not respond or who have a recurrence can subsequently be treated by surgical excision.
