Disordered oesophageal motility in thyrotoxic myopathy.

Dysphagia is an uncommon feature of thyrotoxic myopathy, and is usually associated with other signs of bulbar weakness, such as dysarthria and nasal regurgitation. We report a case of thyrotoxicosis presenting with dysphagia due to diminished oesophageal motility associated with significant hypercalcaemia; both abnormalities resolved rapidly following treatment.
