“…The prevalence of Ewing's sarcoma in our study was between 10 and 20 years, consistent with the age of onset for this sarcoma (20,21). The imaging presentations in one such patient was expansile bone destruction with thinned discontinued cortex, ill-defined margins but no soft tissue masses (Figure 3).…”

Background: The clinical and imaging presentations of primary tumors and tumor-like lesions in the clavicle are not clear. Objectives: To investigate the clinical and imaging presentations of primary tumors and tumor-like lesions in the clavicle for better diagnosis. Patients and Methods: Patients with clavicular diseases between 1963 and 2018 confirmed by pathology who had plain radiography, computed tomography (CT) scan and magnetic resonance imaging were enrolled. The age, sex, imaging data, radiological signs and location of the tumor at the clavicle of patients were analyzed and compared. Results: Eighty-one patients with clavicular diseases were identified including 49 males and 32 females with an age range of 2 - 76 years (mean, 42.6). There were malignant tumors in 50 cases (61.7%), intermediate in 12 (14.8%), and benign in 19 cases (23.5%). Malignant tumors included metastatic tumors in 31 cases (38.3%), plasma-cell myeloma in ten (12.3%), and osteosarcoma in four (4.9%). The intermediate bone tumors were mainly eosinophilic granuloma in six cases (7.4%), and aneurysmal bone cyst in three (3.7%). Benign tumors were mainly osteochondroma (6.2%), bone cyst (3.7%), and chondroma (3.7%). Malignant tumors had bone destruction, periosteal reaction, ill-defined margins and soft tissue masses. Benign tumors and tumor-like lesions had well-defined margins. Conclusions: Many tumors may occur at the clavicle with more malignant than benign tumors with no specific imaging features in most lesions. A lesion near the sternal end with atypical benign imaging features should be considered as malignant.

Osteosarcoma comprises 23% of head and neck malignancies. Studies show that 6% to 9% of all osteosarcomas are seen in the maxilla and mandible. In osteosarcoma in jaws, the survival rate is higher and the risk of metastasis is lower compared to osteosarcoma in the extremities. The gold standard in osteosarcoma diagnosis is computed tomography and magnetic resonance imaging. 'Sunray appearance' is a common radiologic finding of sarcomas. A 29-year-old male patient received to our clinic with pain and swelling in the right mandible. Extra-oral examination revealed that facial asymmetry and significant swelling in the right mandible. On the cone beam computerized tomography examination, a lytic, mixed lesion area was observed with conical shaped root resorption around the mandibular right second premolar and first molar tooth roots. Ultrasound examination revealed that thinning, expansion, and erosion of the buccal cortical bone and 'sunray appearance' in the mandible. Cone beam computerized tomography and ultrasound have become an important diagnostic technique for the evaluation of maxillofacial pathologies. Ultrasound imaging is a rapid technique that aids in the early and differential diagnosis of pathologies. Sunray appearance is a pathognomic finding for osteosarcoma. In present case report, diagnostic ultrasonography is the second case in the literature used in osteosarcoma of the mandible.

“…However, such appearance on sonography has been described rarely in the literature, in osteosarcoma of the mandible. [11,12] This is important because the sunburst appearance was not seen on radiography but was seen on sonography.…”

Periosteal reaction may be classified as benign or aggressive based on the time course of the initiating process. Benign periosteal reaction is a low-grade chronic irritation which allows time for the formation of normal or near-normal cortex. The cortex will be thick and dense and has a wavy or uniform appearance. Benign periosteal reactions can be seen in callus formation in a fracture or with slowly growing tumours. Aggressive periosteal reaction is a rapid irritation process that does not allow the periosteum time to lay down and consolidate new bone to form normal cortex. The cortex may appear lamellated, amorphous, or sunburst-like. Aggressive periosteal reactions can not only be seen with malignant tumours, but also with more benign processes like infection, eosinophilic granuloma (Langerhans cell histiocytosis), aneurysmal bone cyst, osteoid osteoma, haemophilia, and trauma.
