Purpose
Primary malignant bone tumors are uncommon in pediatrics compared to metastatic tumors, benign tumors, and tumor mimics. The diagnosis is based on clinical and radiographic features. The objective of this study is to investigate the imaging characteristics of primary malignant bone tumors in children.
Methods and materials
The imaging results of 21 children with primary malignant bone tumors confirmed by histopathological diagnosis between March 2017 and July 2022 were retrospectively analyzed. This study was conducted in the radiology department of the children university hospital Abderrahim El Harouchi in Casablanca.
Results
Results:
11 patients had osteosarcoma, with radiography and computed tomography (CT) showing osteolytic bone destruction or/andosteoblastic bone sclerosis as well as an aggressive periosteal reaction, a soft-tissue mass and cancerous bone. The tumors appeared as mixed magnetic resonance imaging signals that were inhomogeneously enhanced. A total of 8 patients presented with Ewing sarcoma, with radiography and CT showing invasive bone destruction and a soft-tissue mass. On MRI theyhad mixed low signal on T1-weighted images and high signal on T2-weighted images. 1 patient had chondrosarcoma presenting...
Conclusion
Imaging modalities play an undeniable role in the diagnosis, staging and follow up of primary malignant bone tumors as was illustrated in our cases.
