A hard nut to crack?

Doctors in India soon discovered this elderly man’s case was a little tougher than they first thought.
The 80-year-old presented to their urology department with haematuria and voiding lower urinary tract symptoms.
On physical examination, they noted a grossly enlarged right testis that felt “stony hard”.
But a contrast-enhanced CT cracked the diagnosis, revealing a hydrocele in the right scrotal sac that appeared to have developed a thick, eggshell-like calcification around its outer layer.
