“…This appearance is, however, non-specific, since it is also seen in aggressive infections such as actinomycosis [10] and in malignant tumors. Osteosarcoma of the rib usually presents as a soft tissue mass but is associated with extensive calcifications within the soft tissue mass [11].…”

The objective of this study was to determine the utility of CT scan findings for the diagnosis of chest wall tuberculosis, excluding the spine. We reviewed 15 patients (13 Africans and 2 Indians) with chest wall tuberculosis, retrospectively. The radiologic examination consisted of a plain X-ray and a CT scan of the chest for each patient. The site of disease was the rib in 13 patients or the body of the sternum in 2 patients. One rib was involved in 11 patients, 2 contiguous ribs (one site) in 2 patients, and bilateral disease (two sites) was observed in the remaining patient. The 14 rib sites involved the posterior arc or costovertebral joint in 11 cases, the anterior arc in 2 cases, and the anterior and middle arc in 1 case. The CT scan findings were an abscess (n = 14) or a soft tissue mass (n = 2), osteolytic lesions (n = 13), periosteal reaction (n = 10), and sequestrum (n = 14). Bone sclerosis was observed only in 3 cases of rib involvement. The association of a soft tissue abscess, an osteolytic lesion, and sequestrum, especially in immigrants to France, suggests chest wall tuberculosis on CT scan.

“…This indicates of the differentiation from more common lesions that may be confused on radiographs (3). Although our case on the rib did not show characteristics of calcification, the CT is useful for differentiation of chondroid tumor, in which the hypodense chondroid matrix and punctate calcifications are some of the specific findings.…”

“…However, with simple radiograph, the characteristic features of the PEROSA arising from the rib or scapula may be visualized suboptimally, and may be misinterpreted as a lung cancer, pleural lesion, and other variety of disease (2, 3, 6, 7). The radiologically differential diagnoses of PEROSA include fracture with callus, periostitis, heterotopic ossification, calcific tendinopathy, other primary bone surface tumors (parosteal osteosarcoma, periosteal chondrosarcoma, high-grade surface osteosarcoma), metastatic carcinoma, and tuberculous infection of the chest wall (2, 3). The post-fracture callus tends to have a more conspicuous and orderly deposition of the osteoid and immature bone (2).…”

“…PEROSA of the chest wall, unlike that of the extremities, presents a diagnostic challenge because of the extreme rarity of the lesion, variable clinical symptoms, and suboptimal visualization on radiography of the characteristic features, resulting in misinterpretation of the lesion as a variety of other diseases (3). We present with radiologic findings and review of literature, of the two cases of PEROSA arising from the rib and the scapula.…”

Periosteal Osteosarcoma Arising from the Rib and Scapula: Imaging Features in Two Cases

Periosteal osteosarcoma is an extremely rare chondroblastic osteosarcoma in the flat bone. There were authors reporting of two cases of periosteal osteosarcoma in the highly unusual sites. One of them arose from the rib, in a 17-year-old male, which appeared as a hypodense juxtacortical mass with periosteal reaction on CT. The other one arose from the scapula, in a 17-year-old female, which showed the intermediate signal intensity (SI) on T1-weighted image (WI), heterogeneous high SI on T2WI, and rim-enhancement on contrast-enhanced T1WI with cortical destruction on MRI.

“…4 A primary osteosarcoma of rib is extremely rare. [5][6][7][8] Most positive findings on bone scan in relatively young patients with back pain are due to non-malignant etiology, such spondylolysis, osteomyelitis, or osteoid osteoma. [9][10][11][12][13][14][15] However, different malignant disorders, 16,17 including the current one, can also be incidentally identified in young patients with back pain.…”

Osteosarcomas generally arise in appendicular skeletons, but rarely in the ribs. We described Tc-MDP bone scan findings from a 23-year-old man with right back pain. The images demonstrated elevated activity in the region overlapping the posterior 8th to 10th ribs and in the L9-10 vertebral bodies. CT showed an 8.8 × 8.3 cm mildly peripherally calcified mass arising from the right 10th rib involving the 9th and 10th thoracic vertebrae. Pathological examination confirmed primary osteosarcoma of the rib.
