chondroblastoma/edema

OBJECTIVE To review the imaging findings, age and gender distribution of chondroblastoma of the hands and feet. METHODS Twenty-five cases of pathologically proven chondroblastoma of the hands and feet were reviewed. Available imaging modalities included radiographs (n=24), CT (n=3), MRI (n=5), and

The authors describe a young adult patient with a chondroblastoma and associated aneurysmal bone cyst of the cuboid. Although chondroblastoma has been reported to occur in tarsal bones, the cuboid is a very rare location. The association of chondroblastoma with an aneurysmal bone cyst in long bones

The chondroblastoma is a rare lytic osseous lesion, which is typically to be found in the epiphyses of the long tubular bones. We present a case report with the differential diagnostic imaging and the surgical therapy of a chondroblastoma of the proximal tibial epiphysis. A 16-year-old male

To investigate the frequency and mechanism of the peritumoral inflammatory reaction in chondroblastoma, we evaluated the relationship between clinicoradiological findings and immunohistochemical expression of cyclooxygenase-2 (COX-2) in excised tumors. Twenty-one cases of chondroblastoma were

BACKGROUND Chondroblastoma is a rare, benign tumor derived from chondroblasts, is almost exclusively an epiphyseal lesion, although it may secondarily extend into metaphysis. It is most commonly found in lower extremity with most common sites being distal femur followed by proximal femur, proximal

Chondroblastoma is a rare benign chondroid bone tumor, which typically arises from the epiphysis of a long tubular bone. We present a 13-year-old girl with persistent hip synovitis caused by a chondroblastoma that arose from the femoral neck (metaphysis) and uniquely extended extraosseously into the

OBJECTIVE The objective of this study was to evaluate the inflammatory reaction accompanying chondroblastoma and to define the value of the finding in clinical practice. METHODS We reviewed the clinical, radiographic, and magnetic resonance (MR) findings in six patients with histologically proven

OBJECTIVE To describe the imaging findings, with special emphasis on the magnetic resonance (MRI) findings and the clinical and radiological presentation of chondroblastoma. METHODS This is a retrospective study of 18 patients (12 men and 6 women; mean age, 19 years) diagnosed with chondroblastoma.

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

We report a case of intra-articular intracortical chondroblastoma of the femoral condyle which radiologically appeared to be osteoid osteoma. A 19-year-old woman presented with a 3-year history of gradually increasing pain in the right knee and had been on nonsteroidal anti-inflammatory drugs for

OBJECTIVE To determine the age distribution, gender, incidence, and imaging findings of vertebral chondroblastoma, and to compare our series with findings from case reports in the world literature. METHODS Case records and imaging findings of nine histologically documented vertebral chondroblastomas

OBJECTIVE To define the characteristics of chondroblastoma at magnetic resonance (MR) imaging and the combination of findings that are diagnostic for chondroblastoma. METHODS From January 1987 through December 1992, 22 patients with histologically confirmed chondroblastoma and prior MR imaging

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

OBJECTIVE Epiphyseal/apophyseal locations are important diagnostic radiological features of chondroblastomas (CB). Although the tumor may secondarily involve the metaphysis, reports of primary metaphyseal or diaphyseal CB without any epiphyseal or apophyseal involvement are exceptionally rare and

A study was performed to determine the frequency of periosteal reaction associated with chondroblastoma, to investigate the underlying pathophysiology of the periosteal reaction, and to postulate the clinical importance of this radiographic observation. Two hundred fourteen histologically proved
