Abstract

Objective The purpose of our study was to report the imaging characteristics of 12 highgrade surface osteosarcomas diagnosed staged treated and followed up in a single institution Design and patients There were 3 females and 9 males ranging in age from 15 to 34 years mean 20 years The radiological documents plain films in all patients CT scans in 8 and MR images in 6 were reviewed and compared with the histological findings Results Disease sites were the femur 7 tibia 4 and fibula 1 Tumor size varied from 6 to 17 cm The cortex appeared normal in two patients thick in seven and/or thin in five The tumor showed dense ossification in all except in one case where ossification was slight Minimal marrow involvement was visible in two cases on CT/MRI Only one case exhibited a satellite nodule in a previous biopsy tract Two cases radiologically mimicked periosteal osteosarcoma Conclusion Highgrade surface osteosarcomas are often characterized by the presence of an ossified mass contiguous with and originating from the cortical bone with no or minimal marrow involvement
