Osteochondroma of Rib (benign)
IMAGE 1. Specimen of a typical or common rib osteochondroma, resected. Its size is usual or average.

IMAGES 2–13:
A Sizeable osteochondroma, measuring 6.7 × 4 × 2.2 cm. Its shape is irregular as it were to consist of two components. The tumour is located in the 4th rib (right–sided, antero–lateral aspect of it) of a 26–yo male athlete, a non–smoker. Radiological incidental finding.

Preoperative imaging investigations (CXR, CT, MRI scans, 99mTc bone scan with a SPECT / CT study) and photographs of the resected specimen.

Green arrows: the Tumour (osteochondroma).

Yellow arrows: the normal or healthy–appearing part of the rib (as well as the surgical resection margins)
