Oropharyngeal dysphagia in adults is secondary to either a structural lesion or neuromuscular disorder of the upper esophageal sphincter. In cricopharyngeal
achalasia
(incomplete relaxation of the upper esophageal sphincter), the etiology is usually either related to neck surgery or other neuromuscular disorders. We report on a rare case of neuromuscular oropharyngeal dysphagia secondary to bone metastases to the base of the skull. The patient is an 81-year old man with prostate cancer with metastases to the sacrum. A gastroscopy was attempted to discern the etiology of his dysphagia, but the endoscope could not be advanced. A barium swollow showed cricopharyngeal
achalasia
, and an magnetic resonance image of the brain demonstrated bone destruction to the floor of the left posterior fossa in the region of the jugular foramen and foramen magnum. The bone destruction caused disruption of the glosso-pharyngeal and vagus nerves. Selective radiotherapy resulted in rapid improvement in his symptoms. The primary treatment of cricopharyngeal
achalasia
is to correct the underlying process, if possible. This case illustrates an unusual presentation of secondary cricopharyngeal
achalasia
caused by cranial nerve involvement secondary to bone metastases.
