Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of ...

abstract patella is a relative uncommon site for chondroblastoma. most of cases of chondroblastoma in patella reported in literature are treated with patellectomy. we treated a large chondroblastic lesion in patella of an 18- year-old male with curettage, burring & bone graft and the result was satisfactory after 3 years post operation.

Chondroblastoma is a benign tumor that typically arises in the epiphysis of a long bone. There have been only 2 reported cases of chondroblastoma involving the capitate. This is the first report of chondroblastoma with secondary aneurysmal bone cyst involving the capitate. A 33-year-old man presented with a 3-year history of pain and swelling of the right wrist. Radiography as well as computed ...

Aneurysmal bone cyst (ABC) is a rare benign cystic lesion of the bone that composes 1-2% of the entire bone tumors. Some are idiopathic, and some occur secondary to other tumors such as giant cell tumor and chondroblastoma. In this article, we report the clinical, radiographic, and histological findings of a secondary ABC following chondroblastoma of the patella with a review of the literature.

PURPOSE To investigate cytokine production by chondroblastoma in inducing local inflammation and adjacent-joint arthritis. METHODS Immunohistochemical analyses of curetted tissues using anti-human interleukin (IL)-1 beta, IL- 6, IL-8, and tumour necrosis factor (TNF)-alpha were performed for 6 patients with chondroblastoma and 3 patients with giant cell tumour (GCT) of bone. In addition, pros...

thisis a case report of a 24-year-old man who presented with increased pain and firm swelling of the right foot after a minor twisting injury. radiography, computed tomography (ct) and magnetic resonance imaging (mri) findings showed ancillary information that was helpful for surgical treatment. the final diagnosis was confirmed aschondroblastoma of the navicular bone based on the pathology rep...

Chondroblastoma is a benign epiphyseal chondromatous lesion typically seen as small, well-defined, eccentric with thin rim of surrounding bone sclerosis. Soft tissue extension, metaphyseal involvement, periosteal reaction, cortex breach though not pathognomonic, are reported in literature. We present case report patient chondroblastoma showing atypical radiological presentation exophytic mass o...

Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for approximately 1% of all bone tumors and characteristically arises in the epiphysis of a long bone, particularly the humerus, tibia, and femur. Chondroblastoma can affect people of all ages. It is, however, most common in children and young adults between the ages of 10 and 20 years. Although most chondroblastomas are cure...
