A patient belting out a jazz number while undergoing a CT scan would normally have been the strangest thing happening in the radiology department of Manchester Royal Infirmary.

But stranger still was the musician’s neck while performing.

Ballooning out like a bullfrog, the young trumpeter reported a five-year history of this bilateral neck swelling whenever he played, resolving completely between episodes.

Less a ‘frog in the throat’ and more of a ‘frog-like throat’, it had first been pointed out to him at school but only began feeling uncomfortable as he got older.
