Bioplasm-method for differential diagnostics of chondrosarcoma and metastatic lesions

Author:Bioplasm  UpdateTime:2018-10-18

As a rule, malignant neoplasms of locomotor apparatus give different and non-specific clinical symptomatology. In the majority of cases an assumption of malignant lesion of bones appears when, besides clinical manifestations (pain, swelling), roentgenogram also shows pathological changes. It can be various variants of osseous destruction, periosteal reaction, pathologic fractures, changes of soft tissues. At the same time roentgenologic semiotics gas several similar signs at various pathological processes. In particular, a single nidus of osseous lytic destruction, revealed by a roentgenogram, can be a consequence of both chondrosarcoma and metastasis. However due to physical peculiarities of development, traditional roentgenology method cannot differ these two processes. X-ray computed tomography has more possibilities in differing of chondrosarcoma and non-vertebral metastasis. CT may help in defining of osseous destruction length, in evaluation of soft-tissue component structure. Nevertheless if a process is located in long bones, at presence of lytic destruction of soft-tissue component, specificity of this method also decreases. New method of computed three-dimensional Bioplasm-graphy, as we believe, also can be used to detect chondrosarcoma and metastasis. In available references we have not found information about application of Bioplasm-method for differential diagnostics of chondrosarcoma and metastatic lesions.
