Which radiographic description is associated with Multilobular Tumor of Bone?

• A. Ground-glass opacity
• B. Sunburst periosteal reaction
• C. Moth-eaten pattern
• D. Popcorn-like granular radiographic appearance

Answer: (D)

Multilobular tumor of bone typically shows a lytic, expansile lesion with intralesional calcified cartilage forming discrete, rounded mineralized foci that resemble popcorn scattered within the mass. This popcorn-like appearance comes from the tumor’s structure of multiple cartilaginous lobules that gradually calcify as the tumor grows. Other radiographic patterns reflect different processes: sunburst periosteal reaction is classic for osteosarcoma, ground-glass opacity points to fibrous dysplasia, and a moth-eaten pattern indicates aggressive bone destruction from various malignant or infectious processes. The distinct cartilaginous lobule calcifications give the characteristic popcorn-like granular radiographic appearance associated with this tumor.
