1. Bone tumors involving talus are rare and a comprehensive review integrating the imaging findings of talus tumors has not been published yet. 2. By showing various talus bone tumors, characteristic imaging features of them could be suggested.  

Our exhibition will be composed of 4 parts: 1. Displaying 19 bone tumors of the talus collected for 11 years in our institution: detailed pathologic diagnoses in Table 1. 2. Showing other talus tumors on previously reported literatures: osteoid osteoma, osteoblastoma, intraosseous lipoma, epithelioid angiosarcoma 3. Presenting representative imaging features of talus bone tumors (1) Giant cell tumor, chondroblastoma, chondromyxoid fibroma share similar MR morphology and unlike long bones, age of the patients and tumor locations are not helpful factors for differential diagnosis among them. (2) Circumscribed tumor margin regardless of size does not necessarily mean benignancy. 4. Presenting radiographic features that might suggest clues in differentiating malignancy from benignancy (1) Benign mass is likely to have noticeable cystic area or cystic/hemorrhagic degeneration. (2) Malignant mass tends to show nearby multiplicity, extratalar soft tissue extension, or considerable increase in size on follow-up.
