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 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/ct. in both cases, ct images revealed temporal bone defects and sclerotic changes around the tumor. most parts of the ...

Chondroblastoma is a rare benign bone tumor. It commonly affects the epiphysis of long bones during the second and third decades of life. Chondroblastoma of the temporal bone is extremely rare. We reviewed five cases of chondroblastoma arising in the temporal bone. Four cases were female and one was male. The ages ranged from 41 to 60 years (mean, 53.6 years). All cases involved the temporal bo...

Chondroblastoma is a rare tumor which constitutes 1 % of the primary bone tumors . It most frequently arises from the epiphysis of the long bone. Involvement of the temporal bone is rare. Complete removal is a challenge due to anatomical complexity of the involved area including the middle ear and skull base. We encountered a case of temporal bone chondroblastoma that was safely removed by usin...

Chondroblastoma is a rare, benign bone tumor that represents 1-2% of all primary bone tumors. Denosumab, a monoclonal antibody, has been demonstrated to inhibit the growth of giant cell tumors. We report a case of recurrent chondroblastoma of the squamous temporal bone that is currently suppressed with denosumab.

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 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...

A case of chondroblastoma of the temporal bone is reported, and the pathology of the lesion outlined. The rarity of these neoplasms in the skull makes accurate prognosis impossible.

Chondroblastomas are highly destructive tumors that are derived from immature cartilage cells. The occurrence of this tumor in the temporal bone or skull base is uncommon. Approximately 70 cases have previously been reported, several of which have involved the temporomandibular joint (TMJ). We report here the case of a 67-year-old woman who presented with right-sided mixed hearing loss, a right...

We present a case involving a late diagnosis of chondroblastoma of the temporal skull base involving the temporomandibular joint (TMJ). Following an initial misdiagnosis and unsuccessful treatment over a period of 5 years, the patient was referred to our department for further evaluation and possible surgical intervention for occlusal abnormalities, trismus, clicking of the TMJ, and hearing imp...
