osteoblastoma/edema

Osteoblastomas are benign bone tumors that produce prostaglandin and promote inflammation. The aim of the present study was to describe the clinical and radiological characteristics of a pediatric osteoblastoma case over an 8-month postoperative follow-up. The case involved an 11-year-old female

We present what we believe is the first reported case of synchronous osteochondroma and osteoblastoma, occurring in the proximal humerus of a young man. A 15-year-old boy presented with a painful left arm mass for 3 months. A firm mass was palpable in the proximal medial arm, and he had mild triceps

Osteoblastoma is a rare bone tumor involving spine, long bones and infrequently skull, especially with sinus localization. The orbital localization of the neoplasia may cause axial or paraxial exophthalmus, vertical diplopia, pulsatile orbital pain, soft tissue swelling with skin erythema. In

Purpose: To explore the typical magnetic resonance imaging (MRI) pattern of osteoblastoma (OB) after radiofrequency ablation (RFA) treatment and to identify signs indicating treatment success or relapse.Materials and methods: Forty-four follow-up MRI examinations of 15 patients with OB

BACKGROUND Benign osteoblastoma is an uncommon primary bone tumor that usually affects long bones and the vertebral column. Its occurrence in the calvarium is rare. Despite the characteristically benign nomenclature of osteoblastoma, it sometimes recurs with the possibility of transforming into a

METHODS Case report. OBJECTIVE To describe the magnetic resonance imaging (MRI) and computed tomography (CT) findings of spinal osteoblastoma and illustrate how MRI features can be potentially misleading. BACKGROUND Osteoblastoma is a rare benign tumor of bone that is known to incite a localized

To explore the incidence and significance of intra- and extra-osseous edema associated with benign tumors and tumor-like diseases.

Magnetic resonance imaging (MRI) data from 300 benign osseous tumors and tumor-like diseases diagnosed by

A 37-year-old man presented with a 2-year history of left hip pain. Pretherapeutic imaging demonstrated a 4 cm osteoblastoma located in the intertrochanteric region of the proximal femur, surrounded by extensive bone marrow edema. After multidisciplinary meeting, percutaneous cryoablation was

BACKGROUND Several reports have shown peritumoral edema accompanying primary bone tumors demonstrated by magnetic resonance imaging (MRI). However, the mechanism of this inflammatory reaction is still unclear. The authors postulated that the reaction was caused by some chemical mediators including

The data on 98 new patients with osteoblastoma were studied. The clinical features of pain, scoliosis, and neurologic deficit were largely consistent with those in previous reports. Osteoblastoma is usually a lytic lesion originating in the medulla of bones with matrix ossification and mild

Osteoid osteoma is a benign primary bone tumor of unknown etiology that occurs most commonly in males during adolescence and early adulthood. Osteoid osteoma affects the spine in 20% of cases, and may cause spinal deformity, stiffness, and pain that may sometimes be worst at night. We present a

OBJECTIVE Four pediatric patients were sent to our institution with the diagnosis of soft-tissue/malignant bone tumor. In all cases an MRI was the initial study performed for neck or back pain. All were surgically proven to have an osteoid osteoma/osteoblastoma (OO) as a final diagnosis. The MRI

The scaphoid bone of the wrist is one of the most commonly fractured bones in the body. Due to its importance in the biomechanics and functionality of the wrist, it is important to depict and characterize the type of injury. Plain radiographs and scintigraphy may fail to disclose the type and

Osteoid osteoma is characterized by an intracortical nidus with a variable amount of calcification, as well as cortical thickening, sclerosis, and bone marrow edema. When these findings are present, a diagnosis of osteoid osteoma is easily made. However, osteoid osteoma may display imaging findings
