Relevance: Peripheral primitive neuroectodermal tumor (primitive neuroectodermal tumor – PNET) belongs to the group of malignant tumors that develop from migrating embryonic neural crest cells. PNET includes several nosological forms: Askin’s tumor, esthesioneuroblastoma, the very peripheral primitive neuroectodermal tumor, and Ewing’s sarcoma. PNET accounts for 3–9% of all soft tissue tumors and 19% of all soft tissue sarcomas in children. In Europe and the US, PNETs account for 3.4 cases per year per 1 million children below 15 years; in Kazakhstan – 0.6-1.2 cases per 1 million child population. Rapid tumor growth, malignancy, and early metastasis to other organs and systems predetermine the PNET’s specific role in oncology. The purpose of the study was to improve the quality and availability of early sarcoma diagnostics in children at medical institutions of the general medical network. Results: 35 cases of peripheral PNET in children were analyzed. The age of the patients was 1.5 to 17 years, the average age – 9.3 years. Boys were 1.3 times more than girls. One patient (3.6%) had extra-skeletal tumor localization. Children with stage IIB prevailed – 46.4% of cases (13 children). Radiographical differentiation between Ewing’s sarcoma and primary chronic or “healed” (antibiotic) acute hematogenous osteomyelitis in the initial phase of the process is almost impossible before the extraosseous soft tissue component is formed. The bone damage process is more often localized in the bone diaphysis and subsequently spreads to its metaphyses. Conclusion: PNET is more likely to come from the chest wall, so it is advisable to start the X-ray examination from the chest. In terms of radiation semiotics, PNET is similar to Ewing’s sarcoma and Askin’s tumor; therefore, an additional immunohistochemical study of the tumor tissue is required. An important indirect diagnostic criterion in Ewing’s sarcoma is the predominance of the soft tissue component over the bone manifestations. Extended CT and MRI studies with contrast enhancement (chest, abdominal cavity, pelvis, and the primary lesion area) and skeletal scintigraphy are required to clarify the extent of changes, stage the tumor accurately, and assess the tumor dynamics after treatment. The above conclusions generally confirm the available literature data.

52-year-old woman with a sacral mass that was incidentally identified after minor trauma Axial T1-weighted FSE images (Figure 14.19.1) and fat-suppressed T2-weighted FSE images (Figure 14.19.2) reveal a lobulated mass with marked T2 hyperintensity originating in the sacrum and having a large anterior soft tissue component. The mass is predominantly hypointense to skeletal muscle on the T1-weighted images, with smaller regions of increased signal intensity. Sagittal fat-suppressed T2-weighted FSE images (...

Juxtacortical Osteosarcoma (OS) presents with three sub-types. These include parosteal OS, periosteal OS, and Highgrade surface OS. Imaging diagnosis of sub-types of Juxtacortical osteosarcoma is difficult. However, an analysis of 14 cases of these sub-types presents a spectrum of findings in each entity. The analysis of the Site, Transitional zone, Age, Matrix mineralization, Periosteal reaction, and Soft tissue component (STAMPS) are essential in making the final diagnosis and differential diagnosis.

ABSTRACT Study design Retrospective analysis of data of those patients who underwent a percutaneous transpedicular biopsy at our hospital was done. All patients had a bony lesion in a vertebra (thoracic, lumbar, sacrum) without a soft tissue component around the bone and neurodeficit. Objective To analyze the role of percutaneous wide bore needle biopsy in vertebral lesions without any soft tissue component. Summary of background data Adequate treatment of spinal lesions requires formulation of diagnosis-best achieved by a tissue biopsy when all attempts at diagnosis fail by noninvasive methods. Percutaneous CT guided fine needle biopsy is technically difficult in intraosseous lesions leading to frequent inconclusive results and hence the necessity of wide bore needle biopsy. Materials and methods Retrospective analysis of data of 26 patients with mean age of 58.8 years who underwent a percutaneous transpedicular biopsy at our hospital was done. All patients had a bony lesion in a vertebra (thoracic, lumbar, saccrum) without a soft tissue component around the bone and neurodeficit. The procedure was done under local anesthesia with sedation. Results Positive diagnosis was achieved in 23 out of 26, i.e. 88.4% of cases (adequacy). Out of 26, there were 13 cases of malignancy (50%), 8 cases of tuberculosis (30.7%), 2 cases of osteoporosis (7.6%) and biopsy was inconclusive in 3 (11.5%) cases. Of the 13 malignancies, 7 cases were of metastasis (53.8%), 5 cases of plasmocytoma (38.4%) and 1 case of lymphoma (7.6%). Conclusion Percutaneous biopsy under fluoroscopic guidance by transpedicular approach is quite safe and gives high adequacy (88.4%) without significant complications that are associated with open and paraspinal techniques.
