• Two diabetic patients presented with fecal incontinence, poor rectal sphincter tone, perianal hypoesthesia, and absent Achilles reflexes. These signs suggested the conus medullaris syndrome; however, no mass lesion was found to account for the clinical features. Fecal incontinence can occur in longstanding, insulin-dependent diabetics. Back pain and absence of autonomic and peripheral neuropathy should indicate an etiology other than diabetic neuropathy.
