Osteoblastoma of the lumbar spine in an adolescent: A case report and review of literature

Journal of Clinical Orthopaedics, 2021

Introduction: Osteoblastomas are primary bone tumors representing 1% of all bone tumors and 10% of all spinal osseous neoplasms with a predilection for posterior elements. Case Report: A 13-year-old boy with insidious backache for six months presented with progressive radiating paraesthesia and claudication, restricted lumbar motion and positive straight leg test bilaterally with weakness of left ankle dorsiflexion. Radiograph showed an subtle expansile lytic lesion in the L3 posterior elements. CT and MRI revealed a space-occupying lesion of the L3 vertebra lamina, involving the left pedicle causing severe spinal canal stenosis. Excision of the posterior elements of the L3 vertebra including the facet and left pedicle and short segment fixation from L2-L4 using autogenous rib was done. At two years postoperatively, he was asymptomatic, neurologically normal, showing radiographic evidence of union with no recurrence. Conclusions: Autogenous structural rib can be used for posterolate...

Osteosarcoma of the lumbar vertebra: case report and a review of the literature

Archives of Orthopaedic and Trauma Surgery, 2009

Epithelioid Sarcoma (ES) is a rare non-rhabdomyosarcoma soft tissue sarcoma. It is a high-grade malignancy that most commonly occurs in young adult males. These tumors are characterized for slow growing nodules with predilection for the extremities. A proximal form arising in the deep part of the pelvis, perineum, and genital tract and proximal extremities has been described. Only three cases with localization to the spine have been reported. We report the case of an 11-year old female with a primary ES of the lumbar spine, who presented with antalgic gait and evidence of L3 vertebral collapse on x-rays. She had upfront surgery for spine stabilization and biopsy. Treatment consisted of neoadjuvant chemotherapy with ifosfamide and doxorubicin, local control with radiation therapy, and secondlook surgery with complete reconstruction of L3. She tolerated treatment well, without significant toxicities or complications. When this paper was submitted for publication, she had completed 6 months of follow up in first clinical remission without evidence of local or distant disease. This is the first case of ES diagnosed at our center, likely the first pediatric case of ES diagnosed in the Dominican Republic; although a national cancer registry does not exist. Establishing the diagnosis would not have been possible without access to international experts in pediatric oncologic pathology thought existing institutional collaboration. This is not a novel case but a diagnostic challenge, issue exacerbated in developing countries. We are proud to have offered appropriate, timely treatment, with a similar integral quality as in a developed country.

Progression of a lumbar spinal osteoblastoma : Case report

Shinkei Geka, 2005

A 24-year-old woman presented with a lumbar spinal osteoblastoma manifesting as a 5-year history of low back pain radiating to the left foot. Neuroimaging showed suspicious hypertrophy of the left L4-5 facet which transformed in 3 years to an expansile mass lesion that compressed the dura mater and neural structures. Primary benign bone tumors such as osteoblastoma and osteoid osteoma should be considered in the differential diagnosis of back pain and the patients should be followed up carefully.

Vertebral Osteosarcoma -A Report of Five Cases

Journal of bone and soft tissue tumors, 2021

Background: Vertebral osteosarcoma is rare, accounting for 3%-5% of all osteosarcomas. It tends to occur in a slightly older age group. The prognosis is poor compared to osteosarcoma of extremities. Case Details: We present five cases of vertebral osteosarcomas. The patient's age ranged from 16 years to 54 years. There were four females and one male. They presented with pain, swelling, or weakness of limbs. Destructive lesions, mixed lytic and sclerotic lesions involving vertebral bodies, and/or pedicles were seen on imaging. A definitive diagnosis could not be made in two cases. On histopathological examination, all the cases turned out to be osteosarcomas. Conclusion: Osteosarcoma of vertebrae has high rate of recurrence, metastasis, and mortality. Differentiation of vertebral osteosarcoma from other common bony lesions involving the spine is of utmost importance as the treatment is entirely different. Combination therapies including surgery, radiation, and chemotherapy achieve adequate short-term survival rates for vertebral osteosarcoma.

Primary Vertebral Osteosarcoma: Imaging Findings1

Radiology, 2004

PURPOSE: To evaluate patient age and sex and location and imaging appearances of primary vertebral osteosarcoma (PVOS) compared with histologic subtypes. MATERIALS AND METHODS: Retrospective review (1915-2001) of imaging findings in patients with histologically proved primary osteosarcoma of vertebral column was performed. Two radiologists in consensus reviewed findings for location, origin site, matrix pattern, and spinal canal invasion and compared them with histologic subtypes. Radiation-induced, Paget, metastatic, and multifocal osteosarcoma were excluded. RESULTS: Of 4,887 osteosarcoma cases, 198 (4%) were PVOS arising from vertebral column. There were 103 female and 95 male patients (age range, 8-80 years; median age, 34.5 years). Involvement included cervical (27 patients), thoracic (66 patients), lumbar (64 patients), and sacral (41 patients) spine. Adequate imaging findings were available in 69 patients, and involvement of two levels was seen in 12 (17%). In nonsacral spine, most tumors (44 cases) arose from posterior elements, with partial involvement of vertebral body. Lesions confined to vertebral body were less frequent (12 cases). Sacral tumors involved body and sacral ala. The most common histologic subtypes were osteoblastic (47 patients), chondroblastic (12 patients), telangiectatic (four patients), fibroblastic (four patients), small cell (one patient), and epithelioid (one patient). The majority (55 cases) demonstrated osteoid matrix mineralization; 17 showed marked mineralization. Five cases with marked mineralization were confined to vertebral body, with "ivory vertebra" appearance. Purely lytic pattern was seen in 14 (20%) cases. Lytic pattern was seen in four (100%) telangiectatic, three (75%) fibroblastic, three (25%) chondroblastic, three (6%) conventional osteoblastic, and one (100%) small-cell subtypes. Invasion of spinal canal was common (84% of cases). Appearance simulating osteoblastoma without soft-tissue mass was present (seven cases). Pathologic compression fractures were identified (seven patients). CONCLUSION: This study provides age and sex distribution and location and imaging features in a large series of PVOS.

Ossifying fibroma – diagnosis, treatment, and follow-up: case report and literature review

Revista Odonto Ciência, 2017

OBJECTIVE: This article presents a case of ossifying fibroma (OF), including its diagnosis, treatment, and 15-month clinical and radiographic follow-up as well as a review of the literature about this pathology. CASE REPORT: A routine panoramic radiograph of a 27-year-old, systemically healthy, white woman revealed a radiolucent lesion with well-defined sclerotic margins of approximately 3 × 2 cm in the mandible. The histopathological diagnosis revealed it was an OF. Lower Right Canine and Lower Right First Premolar teeth were endodontically treated for later surgical removal of the tumor. There was no history of trauma in the region. CONCLUSION: OF is a benign fibro-osseous tumor of the craniofacial bones commonly involving the jaws, especially the mandible. The diagnosis is based on a combination of clinical, radiographic and histologic criteria. Conservative treatment is an effective option that reduces morbidity and simplifies postoperative rehabilitation. We emphasize the importance of properly documenting individual cases and interpreting postoperative radiographic images along with the patients in order to avoid possible confusion between areas of bone repair and of potentially suspicious lesions in the future.

Surgical Treatment of Ossifying Fibromyxoid Tumor Invading the Lumbar Spine - A Case Report

Journal of Korean Society of Spine Surgery, 2009

Ossifying fibromyxoid tumor is rare soft tissue neoplasm of an uncertain histogenesis, and this was first described in 1989. The majority of the reported cases have involved the soft tissue of the extremities. We present here on a case of atypical ossifying fibromixoid tumor that had invaded the spine and we report on its management and outcome. We also review the relevant literature.
