The diagnostic workup encompassed radiography, contrast-enhanced CT, and bone scintigraphy with SPECT. Contrast-enhanced CT included subsequent image analysis with three-dimensional volume rendering and cinematic rendering. Cinematic rendering from contrast-enhanced CT (Figure, Movie) showed a giant mass of the right femur (22.1 × 17.5 × 27.8 cm). Findings depicted in the cinematic rendering included osseous tumor matrix spreading through the medullary cavity and circumjacent extraosseous soft tissue, as well as tumor-feeding vessels and dilated superficial veins.Cinematic rendering from contrast-enhanced CT in a 10-year-old girl with giant osteosarcoma of the right femur. (A) Medial sagittal cinematic rendering with wide window settings depicts the extension and superficial details of the mass, including dilated veins and adjacent muscles. (B) Cinematic rendering of a sagittal section shows osseous tumor components (white arrowheads), tumor-feeding arteriole (white arrow), and bone marrow involvement (blue arrow). Adjacent soft tissue tumor components are depicted in red.Download as PowerPoint Movie: Cinematic rendering from contrast-enhanced CT in a 10-year-old girl with a giant osteosarcoma of the right femur. The medial sagittal cinematic rendering presents an overview of the right thigh with different window settings showing high-contrast bone, osseous tumor matrix, tumor-feeding arterioles, soft-tissue components, and superficial veins.Download Original Video (45.9 MB)Cinematic rendering significantly enhances the generation of photorealistic three-dimensional images from CT data, resulting in a remarkable level of realism, particularly when visualizing structures with strong contrast enhancement at contrast-enhanced imaging, such as vessels and bones (1,2). Combining different window parameters in and across sections in cinematic rendering enables improved depiction of different tissue components such as the osseous and soft tissue tumor matrices in the case presented here. Potential applications include both surgical planning and medical education.Disclosures of conflicts of interest: Z.L. No relevant relationships. X.S. No relevant relationships.References1.
