Osteoblastoma of the Spine With Discordant Magnetic Resonance Imaging and Computed Tomography Imaging Features in a Child

Abstract

This case illustrates that the MRI findings for osteoblastoma can be misleading and caution should be used when evaluating benign tumors with known inflammatory responses on MRI. CT features seem to more accurately reflect the true nature and extent of the tumor.

Osteoblastoma of the rib with CT and MR imaging: a case report and literature review

“…Therefore the radiological appearance of osteoblastomas are extremely variable and not specific [6,7]. Accurate preoperative diagnosis is often difficult and aggressive characteristics may be misinterpreted as signs of a malignant neoplasm.…”

A clinicopathologic correlation in osteoblastoma of the spine in a child

“…4 This differs from more malignant pathology, for example lymphoma, Ewing's sarcoma, and osteosarcoma, which will have malignant changes on CT scan as well. 12 However, these tumors can be locally aggressive and result in neurologic deficits from compression of neural elements. Unlike osteoid osteomas, osteoblastomas have been reported to recurat rates ranging from 10% to 24% 13-15 -and undergo malignant degeneration.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] MRI is the preferred imaging modality to diagnose disc herniations, but imaging resolution may not be adequate to identify the intradural component of the disc herniation preoperatively. 1,4,19,20 We present a patient with thoracic intradural disc herniation at T12-L1 that was identified intraoperatively by thecal sac palpation.…”

A Rare Case of Rib Osteoblastoma: Imaging Features and Review of Literature

“…The adjacent bone to the benign osteoblastoma is often not sclerosed (6-8). The radiographic features are varied and often non-diagnostic, but have characteristics similar to osteoid osteoma, depicting a normal or oval, well-circumscribed lytic defect that is surrounded by a zone of reactive sclerosis (9). In our case, the relevant lesion radiographically demonstrated features of osteoblastoma consisting of osseous expansion and well-defined spongy form sclerosis without any internal lucency.…”
