1. Case introduction Patients, male, 28 years old, farmer. After 3 months of falling injury, 3×3cm~2 soft painful masses appeared behind the right lower leg and a little reddish effusion was pumped out in the local area. After 10 days of hematoma heat, the mass increased, and the color ultrasound was still reported as local hematoma. The X-ray showed: 2cm long worm-like bone destruction at the lower end of the right sacrum, light periosteal reaction, local soft tissue swelling. CT scans of 3×3×1cm~3 cystoid bone destruction and 7×7×4cm~3 soft tissue lumps underneath the right sacrum were obscured at the edges, and the center density was slightly lower (CT value 22Hu). X-ray and CT preliminary diagnosis: bone tuberculosis below the right sacrum, cold abscess formation.
