Bone tumors in children represent a heterogeneous group of diseases, differing in biological activity, clinical course, and prognosis. Due to the widespread overlap of symptoms and radiological manifestations between inflammatory processes, benign neoplasms, and malignant tumors, childhood requires the most accurate and comprehensive diagnostic approach. Multimodal diagnostics - the combined use of clinical, radiation, laboratory, and morphological methods - is a key tool for reducing the number of diagnostic errors and timely selection of the correct treatment strategy.
