Pseudogout: an unusual and forgotten metabolic sequela of parathyroidectomy.

BACKGROUND 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. METHODS We present a case of a 71-year-old woman who developed pseudogout following removal of a parathyroid adenoma. RESULTS Although infrequent, pseudogout predominantly occurs in the immediate postoperative period. CONCLUSION 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.
