Objective. The default window setting on PET/CT workstations is soft tissue. This study investigates whether bone windowing and hybrid FDG PET/CT can help differentiate between malignant and benign primary bone tumors. Materials and methods. A database review included 98 patients with malignant (n=64) or benign primary bone (n=34) tumors. The reference standard was biopsy for malignancies and b...

The diagnosis of a bone tumor in a child can be a source of great anxiety for the patient, the parents, and the treating physician. Fortunately, most bone tumors in children are benign. Although there are a variety of benign bone tumors that affect skeletally immature patients, most have such characteristic clinical and radiographic presentations that the diagnosis can be made with reasonable a...

The learning objectives of this review article are to identify benign vs. malignant criteria in bone tumor diagnosis and also to differentiate the types of bone tumors and their characterization. Based on the Lodwick classification an overview of the three main types of bone destruction patterns visible on radiographs will be given with many examples. Typical examples of benign and malignant bo...

Phyllodes tumors are rare fibroepithelial neoplasms of the breast, classified as benign, borderline, or malignant based on histological features. Osseous metaplasia, characterized by presence bone formation within tumor, is an uncommon finding. This case report highlights rarity osseous metaplasia in a benign phyllodes tumor. A 23-year-old female presented with gradually enlarging lump left bre...

IMAGE-guided percutaneous methods of tumor destruction have proven effective for treatment of benign bone tumors as well as for palliation of metastases involving bone and soft tissue sites beyond the liver and lung. Treatment of primary bone tumors is largely restricted to benign tumors, most notably osteoid osteomas, as a single-modality treatment or as an adjunct to surgical resection (1– 4)...

BACKGROUND Benign and malignant bone tumors can present similar imaging features. This study aims to evaluate the significance of apparent diffusion coefficients (ADC) in differentiating between benign and malignant bone tumors. METHODS A total of 187 patients with 198 bone masses underwent diffusion-weighted (DW) magnetic resonance (MR) imaging. The ADC values in the solid components of the ...

OBJECTIVE To analyze different fluid-fluid level features between benign and malignant bone tumors on magnetic resonance imaging (MRI). MATERIALS AND METHODS This study was approved by the hospital ethics committee. We retrospectively analyzed 47 patients diagnosed with benign (n = 29) or malignant (n = 18) bone tumors demonstrated by biopsy/surgical resection and who showed the intratumoral ...
