Axial (image 1) and sagittal (image 2) T2-weighted MR images of the tibia show the expansile lesion arising from the mid tibia. At biopsy and resection, this tumor was confirmed to be an adamantinoma. Adamantinomas are primary low-grade malignant bone tumors. More than 80% occur on the anterior surface of the tibial diaphysis. Patients present with pain and swelling at the site of the tumor. #FridayQuizDay #FridayQuiz

Coronal (image 1) and sagittal (image 2) CT shows the triplane fracture of the distal tibia. The sagittal-vertical component (arrow, image 1) of the fracture is seen within the epiphysis of the tibia. The horizontal component of the fracture extends along the lateral tibia physis (arrowhead). The coronal-vertical component of the fracture extends through the epiphysis and metaphysis of the tibia (dashed arrow, image 2). CT can be used to determine if internal fixation is needed. A fracture gap of more than 2 mm requires screw placement.](https://app.figure1.com/case-detail/4917ec28-25fb-4a5b-9e18-f3576693138b)



Osteosarcoma: This is an X-ray of a Tibia showing a classical conventional osteosarcoma of the upper Tibia. Conventional osteosarcomas are the most common type of osteosarcoma. They are rare tumors. Approximately 600 occur in the United States per year. Most affect children and adolescents.](https://app.figure1.com/case-detail/4ae2324e-212b-456e-9c99-68e58a3ac80c)



Axial CT (image 1), axial T2-weighted (image 2), axial T1-weighted (image 3), and axial T1-weighted postcontrast (image 4) MRI shows a large heterogeneous tumor involving the left posterior parietal lobe. The tumor was diagnosed as a glioneuronal tumor. Glioneuronal tumors are heterogeneous with solid and cystic areas. Calcification and hemorrhage are common.](https://app.figure1.com/case-detail/5a27dde6-743a-479c-8594-7e6f80accc75)



Axial T2-weighted (image 1), T1-weighted (image 2), and postcontrast T1 (image 3) MRI show a well-defined lobulated contoured mass within the left greater trochanter. Mild adjacent soft tissue edema is present. The differential diagnosis for an epiphyseal lesion include chondroblastoma, chondrosarcoma, infection, and giant cell tumor. Giant cell tumors typically occur in the distal femur or proximal tibia. Cortical breakthrough and a soft tissue mass can be present in up to one-half patients. Typically, giant cell tumors are said to occur in patients with a closed physis, affect the epiphysis of the bone, have a well defined non-sclerotic margin, and can be eccentrically located.](https://app.figure1.com/case-detail/9cd8505e-02c2-43d3-819f-3fc9bf273fc8)
