Autonomic dysreflexia and concurrent Horner's Syndrome: a rare presentation in a patient with spinal cord injury.

The patient experienced a transient Horner's syndrome due to autonomic dysreflexia. Both Horner's syndrome and symptoms of autonomic dysreflexia resolved when eliminating the eliciting stimulus, indicating that Horner's syndrome occurred due to a transient pressure on the sympathetic fibres supplying the superior cervical ganglion. Autonomic dysreflexia may have caused increased pressure disrupting the sympathetic input, thus inducing unilateral miosis, ptosis, and facial anhidrosis.
