Vasitis: the need for imaging and clinical acumen.

A 55-year-old man presented with an acute, painful groin mass with signs of sepsis. On examination, it was difficult to tell whether this was a strangulated hernia or a testicular torsion. Biochemical investigations revealed raised inflammatory markers and radiological investigations showed a rare inflammatory condition, vasitis, which could be mistaken for various other 'surgical' groin masses. This case report summarises the importance of realising the vast differential diagnoses that come with acute groin masses and how imaging can prevent unnecessary surgery.
