Background. Pelvic bone tumors rank sixth among all primary bone tumors (about 16 %) and are one of the complex and little-studied problems of bone oncology, not least due to the complex anatomical structure of the human pelvis. The purpose was to substantiate the effectiveness of computed tomography in the detection of tumor foci in the pelvic bones and to determine the features of the technique of controlled transcutaneous puncture biopsy to verify the nosological form of the tumor. Materials and methods. The analysis of examination of 84 patients with tumor lesions of the pelvic bones was carried out by imaging and performing minimally invasive biopsy under the control of spiral computed tomography. Results. Due to the complexity of the diagnosis of this pathology, 54 (64.3 %) of all patients upon admission to the clinic had a different diagnosis (osteomyelitis, osteochondrosis of the lumbar spine, lumbago or neuralgia, myositis, various traumatic injuries). In 29 (34.5 %) individuals, computed tomography revealed the destruction of the bone tissue of the anterior half of the pelvis, 53 (63.1 %) patients were diagnosed with a tumor in the sacroiliac joint or sacrum, in 2 (2.4 %) cases, traumatic damage to the pelvic bones was found, which was mistaken for a tumor process. Histological verification of the diagnosis was performed by controlled transcutaneous puncture biopsy, the technique of which is carefully described and illustrated. Conclusions. Computed tomography allows you to assess objectively the nature of the tumor, its sizes, the degree of destruction of bone tissue, as well as the germination of the tumor in other anatomical structures, provides a detailed assessment of the effectiveness of treatment in the dynamics. Performing a minimally invasive transcutaneous biopsy under the control of computed tomography in an outpatient setting makes it possible to make quickly a morphological diagnosis and immediately prescribe etiological treatment without losing valuable time.
