Pseudogout: an unusual and forgotten metabolic sequela of parathyroidectomy.

Abstract

Parathyroidectomy is increasingly being performed by otolaryngology units. The well-known metabolic sequela is hypocalcaemia; it may be transient or permanent depending on presence and/or activity of any residual parathyroid tissue. A more unusual metabolic sequela of a parathyroidectomy is the development of pseudogout. We summarize the clinical presentation and pathophysiology of pseudogout following parathyroidectomy. We present a case of a 71-year-old woman who developed pseudogout following removal of a parathyroid adenoma. Although infrequent, pseudogout predominantly occurs in the immediate postoperative period. We propose that otolaryngology units should be more aware of the unusual sequelae of pseudogout following parathyroidectomy; it can lead to a prompt referral and commencement of early treatment.
