Autoimmune autonomic ganglionopathy (AAG) is an immune-mediated disorder that leads to various autonomic failures associated with anti-ganglionic acetylcholine receptor antibodies (anti-gAChR-Abs). Diffuse esophageal spasm (DES) is an uncommon esophageal motility disorder. We herein report the case of a 68-year-old woman with DES as a partial symptom of AAG. She presented with chronic esophageal transit failure, constipation, and numbness of the hands and feet, Adie's pupil, thermal hypoalgesia, and decreased deep tendon reflexes. Right sural nerve biopsy showed significantly decreased numbers of small myelinated fibers. Barium swallowing X-ray showed repetitive simultaneous contractions indicating DES in the esophagus. Gastrointestinal endoscopy and CT image showed a dilated esophageal lumen and liquid effusion. Simultaneously, serum anti-gAChR-α3-Ab indicating AAG was detected. After pulse intravenous methylprednisolone (IVMP) and intravenous immunoglobulin therapy (IVIg), the bolus progression and liquid effusion improved, suggesting that DES is an important gastrointestinal symptom of AAG.
