chondromyxoid fibroma is a rare benign cartilaginous neoplasm that mostly affects the metaphyseal region of the long bones. the tibia, small tubular bones of the foot, the distal femur and pelvis are common locations, but involvement of the vertebral bones, especially the cervical vertebra, is very rare. radiographic features show typical characteristics and this tumor often presents as a lobul...

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 ...

Schwannoma is a benign tumor that arises from the sheath of myelinated nerve fibers and may occur in any part of the body. Osteogenesis in schwannoma is extremely rare and, to date, new bone formation in sinonasal schwannoma has not yet been reported. Here, we describe the first reported case of sinonasal schwannoma with new bone formation. The tumor was successfully treated by endoscopic sinus...

The technique of cryosurgery has been used to control local recurrence in a variety of benign and malignant bone tumors. Early studies revealed significant complication rates (25%) that included fracture, infection, and soft tissue injury. Our method of cryosurgery has yielded excellent tumor control with improved complication rates. The objective of this study is to determine the characteristi...

Osteoma is an uncommon bone tumor in avian species and other animals. A 2-year-old male canary (Serinus canaria) with a history of an oval mass in the left wing for several months was examined. Radiographs showed a radio-opaque mass. Upon the bird’s owner request, the canary was euthanatized and submitted for necropsy. The histopathologic examination revealed numerous trabeculae consis...

Objectives: Bone and soft tissue tumors have become more common recognized diseases with developing medical technologies. The life span of the patients has been prolonged effective treatment methods technology. Regardless their area expertise, concept multidisciplinary tumor approach emerged in recent years, since it is difficult for a single physician to manage malignant mass process. For this...

201Tl-SPECT was performed to diagnose the malignancy of bone and soft tissue tumors by visual and quantitative assessment in 48 patients (17 malignant lesions and 31 benign lesions). SPECT images were obtained in the early phase (15 min after injection) and the delayed phase (240 min). By visual assessment a tumor was considered malignant if high accumulation was found in the tumor in the early...

Osteochondroma is the most common benign tumor of bone, occurring either as an isolated lesion or in context hereditary multiple exostoses. In both cases, osteochondroma can arise from ribs, and often asymptomatic. fact, diagnosis follows onset serious complications mechanical interference with neighboring anatomical structures, malignant degeneration., We present a case swelling over right sid...

Adrenal myelolipoma is a rare benign neoplasm of mesenchymal origin composed mature fatty tissue and bone marrow elements. It non-functioning tumor, usually asymptomatic commonly detected incidentally during evaluation for unrelated symptoms; hence, it referred to as an “incidentaloma”. Large myelolipomas can cause mass effects vague abdominal pain, spontaneous tumor rupture with massive hemorr...

They account for 3 to 9% of primary tumors. considered be congenital, but not all them diagnosed at birth. benign choristomas that arise from sequestration ectoderm along the lines embryonic fusion mesodermal processes destined bone. In most cases, lesion is close zygomatic-frontal suture leading a superotemporal subcutaneous m...
