of the temporal bone: Case report and literature review.
The differential diagnosis includes infection like bacterial subacute or chronic osteomyelitis, neoplastic lesions like Ewing sarcoma, osteosarcoma, neuroblastoma metastasis, leukemia, lymphoma, eosinophilic granuloma, osteoid osteoma, and osteoblastoma
Both benign (osteoid osteoma, osteoblastoma
, and chondroblastoma) and malignant (osteosarcoma, Ewing's sarcoma, and chondrosarcoma) tumors, among others, may cause bone marrow edema in all stages of disease.
Differentials suggested by the radiologist included giant cell tumor (GCTB), aneurysmal bone cyst (ABC), osteoblastoma
, or chronic osteomyelitis and advanced imaging was recommended.
[3,4] While primary ABCs are more common, they can also occur secondary to other lesions like osteoblastoma
, giant cell tumour of the bone, chondroblastoma or fibrous dysplasia.
Benign bone-forming lesions: Osteoma, osteoid osteoma and osteoblastoma
. Clinical, imaging, pathologic and differential considerations.
of the mandible: Fifteen year follow-up showing spontaneous regression after biopsy.
Clinicopathologic features and treatment of osteoid osteoma and osteoblastoma
in children and adolescents.
At this time, the pathology was revisited, and a diagnosis of an osteoblastoma
The deposited bone can appear similar to that of an osteoblastoma
. Two reported cases of primary bone PH showed cystic spaces containing necrotic debris and lined focally by hobnailed epithelioid cells; those spaces were thought to be formed by discohesive tumor cells and no true vascular channels were identified.
On the basis of the clinical and radiographic features, the differential diagnosis of this lesion included odontoma, cementoblastoma, and osteoblastoma
. Considering the radiographic features based on the attachment to the tooth root, we ruled out osteoblastoma
