Differential diagnosis of teleangiectatic osteosarcoma and aneurysmal bone cyst (literature review)

The diagnosis of malignant neoplasms of bones often causes difficulties for doctors of all specialties. Despite the fact that many radiological features of malignant neoplasms have been identified (invasive growth, periosteal reaction, destruction of the cortical layer and the presence of a soft tissue component), instrumental diagnostics is a difficult task in making a correct diagnosis. Morphological investigation is a mandatory method for diagnosis, however, at the same time, some nosological units have a similar morphological picture. The differential diagnosis of teleangiectatic osteosarcoma and aneurysmal bone cyst is a particularly difficult task, because these two neoplasms have not only a similar histological, but also a radiological picture. The mistaken diagnoses delay the correct diagnosis and, accordingly, the start of treatment, that affects the patient’s prognosis.
