The Imaging Findings of Primary Chondrosarcoma of Ribs

Objective: To explore the imaging characteristics of primary chondrosarcoma of ribs. Methods: Collected pathologically confirmed 12 cases of primary chondrosarcoma of ribs, retrospectively analyzed the X-ray, CT and MRI. Results: 12 cases of primary chondrosarcoma of ribs with 6 cases of male and female 6 cases. 12 cases of primary chondrosarcoma of ribs located in Costa rib cartilage junction 7 cases, rib bones is located near thoracic vertebra in 4 cases, rib axillary segment in 1 cases, X-ray examination showed for the realm of clear/uniform density of breast lumps(left side in 7 cases and 5 cases of right) and adjacent rib bone structure fuzzy variable. CT scan lesions were osteolytic and expansive bone destruction, local soft tissue mass with clear edge accompanied by the strip, nodular and annular calcification, enhanced CT scan which the lesions(11 cases) no obvious enhancement, adjacent vertebral body and appendix performance for bone erosion damage. 10 cases of primary chondrosarcoma of ribs received MRI examination, Lesions showed as clear boundary long T1 and long T2 mixed signal mass, which enhanced orbicular heterogeneous enhancement. Conclusion: Calcification is the characteristic of primary chondrosarcoma of ribs, boundary clear mass lesion is vital signs, ring strengthen for their enhanced CT/MRI performance characteristics, perfect imaging examination can significantly improve the accuracy of diagnosis and guide the clinical surgery.
