chondroblastoma

A benign tumour that arises in the epiphysis or in secondary ossification centres of long bones (humerus, proximal and distal femur, proximal tibia) of young adults (< age 30).

Imaging
Well-defined lytic lesion with a fluffy cotton-wool appearance, ± sclerotic border.

Extraskeletal Mesenchymal Chondrosarcoma

(3) Chondroid matrix calcifications are described as "ring-and-arcs," which can be seen with enchondromas (Figure 13) and chondroblastomas. Osteoid matrix is described as "cloud-like," which can be seen in osteosarcomas (Figure 7).

Pediatric bone imaging: Differentiating benign lesions from malignant

The majority are considered primary lesions; however, up to 30% can be considered secondary tumors arising from chondroblastomas, osteoblastomas, nonossifying fibromas, and other benign osseous lesions [1].

Recurrent Aneurysmal Bone Cyst of the Distal Fibula Treated with Denosumab and Curettage

Our case showed a lytic lesion with sclerotic rims, and it is difficult to differentiate from other benign bone lesions such as bone cyst, aneurysmal bone cyst, benign chondroblastomas, giant cell tumors, fibrous dysplasia, and nonossifying fibroma; thus, MRI examination was performed.

Intraosseous Schwannoma of the Calcaneus: A Rare Tumor of the Bone

Most of the cases were for treatment of benign bony conditions such as giant cell tumor, UBC, ABC, enchondromas, and chondroblastomas. The group noted overall good results with two local recurrences and one deep infection.

Other differential diagnoses of patellar lesions include Sinding-Larsen-Johansson disease, bipartite patella, and a variety of rare tumors such as chondroblastomas, giant cell tumors, osteoid osteomas, and aneurysmal bone cysts but also malignant tumors [20].

Chondroblastomas usually originates from epiphyseal and apophyeal regions of long bones like humerus, tibia or femur.

Some of the more common masses in the calcaneus include lipomas, solitary bone cysts, and chondroblastomas. Lipomas have characteristic fat signal.
