Diabetic Charcot spine as cauda equina syndrome: an unusual presentation.
Some 6% to 21% of Charcot joints occur in the spine. The underlying disease is usually tabes dorsalis, but diabetes mellitus is another etiology. Degeneration of spinal elements is accelerated and lumbar spinal stenosis with weakness may occur, as has been reported in tabetic arthropathy. The case presented is unusual in two respects: first, the Charcot spine was secondary to diabetic complications, which resulted in a compressive cauda equina syndrome; second, the patient presented with progressive paraparesis and bowel and bladder dysfunction but physical examination by several examiners revealed no clinically evident sensory abnormality. The patient had vague and inconsistent sensory complaints for several years preceding definitive workup, but the overall picture of his disease process only could be made following multiple laboratory, electrodiagnostic, microbiologic, and radiologic testing. The patient presented with subacute paraparesis, providing a wide differential diagnosis ranging from Guillain-Barré syndrome to spinal neoplasm. The physical, radiologic, laboratory, electrophysiologic, histologic/pathologic findings, treatment, and recovery status are included in this report.
