Periosteal osteoblastoma: Multimodal imaging of a rare neoplasm
نویسندگان
چکیده
Osteoblastoma is a rare neoplasm, accounting for only 1% of the primary bone neoplasms. We report a case of periosteal osteoblastoma, a rare subtype of osteoblastoma. To the best of our knowledge, only 30 cases of periosteal osteoblastoma appear in the English literature. Our case is that of a 41-year-old male with vague intermittent knee pain over a two-year period. Diagnostic imaging revealed an aggressive-appearing lesion in the posterior distal femur, which was initially considered to be a surface osteosarcoma. Roentgenographic, CT, MRI, and bone scan features are presented.

Periosteal Osteoblastoma of the Pelvis: A Rare Case
Among the rare bone tumors, the osteoblastoma is a fascinating tumor. The rarity, the predisposition to occur in any bone and the diagnostic dilemma makes this infrequent tumor interesting. It is sporadically reported in the literature and what is rarer is its occurrence in the pelvis. The unusual location and inconclusive radiographic findings with diffused diagnostic evidences delays the mana...

Osteoblastoma is a rare solitary osteoblastic bone neoplasm. It is characterized by proliferation of osteoblasts forming trabeculae within a vascular fibrous stroma. There is a variety of jaw bone lesions with very close clinical, radiological and microscopic interrelations, which make diagnosis more challenging. Familiarity with these rare bony lesions is vital for oral pathologists. This repo...

We reported the case of a 22 year-old boy who suffered a periosteal osteoblastoma of the distal fibula. The radiographic features of our case did not correlate with the majority of periosteal osteoblastomas of the long bones reported in the literature and were identical to a periosteal aneurysmal bone cyst. Periosteal osteoblastoma is a very rare tumor with a wide range of clinical and radiolog...

Osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. It mostly affects the vertebral column and long bones. Radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. Herein, we report a ca...

Osteoblastoma is a rare benign tumor of the calvarium. We present the case of a 20-year-old female with occipital osteoblastoma and discussion of imaging modalities of calvarial osteoblastoma. To our knowledge, this is the ninth reported case of occipital osteoblastoma. Imaging characterization of osteoblastoma may vary. Plain radiograph, CT, MRI, and CT angiography establish osteoblastoma char...
