two new cases of aneurysmal bone cyst of the spine are presented. in one of them only the spinous process was involved, and in the second case mthe neural arch and the body were involved. a brief review of the literature with clinical, radiological and pathilogical features of this benign lesion is made and its differential diagnosis, specially from giant cell tumor of the spine emphasised.

hereby we report a case of well-differentiated intraosseous osteosarcoma in the sacrum. a 32-year-old woman was admitted to our hospital with a low echo-level mass in the pelvis searched by ultrasound in a routine physical examination. radiographically, the mass was misdiagnosed as a benign bony tumor originating from the sacrum. the tumor was completely resected and pathological diagnosis was ...

INTRODUCTION: Almost 200 years ago, Sir Astley Cooper first described osteoclastomas, now called giant cell tumor of bone (GCT). GCTs is cited as the most aggressive benign tumor of the spine with unpredictable outcome. Although deemed benign, GCTs is reported to have tendency for significant bone destruction, local recurrence, and occasionally metastasis. It typically occurs in long bones and ...

PURPOSE The proximal femur is one of the most common locations for benign bone tumors and tumor like conditions. We describe the clinical outcomes of the surgical treatment of benign lesions of the proximal femur including femoral neck using compression hip screw and synthetic bone graft. METHODS Thirteen patients with benign bone tumors or tumor like conditions of the proximal femur includin...

in spite of being histologically benign, sacrococcygeal teratoma (sct) may recur either as a benign or malignant tumor. a total of 26 patients with benign neonatal scts were treated in taleghanee and mofid medical centers from 1986 to 2000. investigations included radiography,abdominal ultrasound and computed tomography (ct) scan and measurement of tumor marker (α-fetoprotein). initial surgical...

Benign osteoblastoma refers to a benign tumor of the bone. Osteoblastoma most commonly affects the vertebrae and long tubular bones, however, in rare cases is observed in the facial bones. The current study presents the case of a 12-year-old female patient with a tumor in the mandibular body. Radiological imaging revealed a lesion with regular contours. The lesion was radically resected and his...

Purpose:Giant-cell tumor of bone (GCTB) is a locally aggressive, benign osteolytic tumor in which bone destruction is mediated by RANK ligand (RANKL). The RANKL inhibitor denosumab is being investigated for treatment of GCTB. We describe histologic analyses of GCTB tumor samples from a phase II study of

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)...

herein, we report the f-18 fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/computed tomography (ct) findings of a benign solitary fibrous tumor (sft) of the kidney. the patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on ct images. the ct scan showed a lobulated tumor arising from the hilum of the right kidney. the tumor consisted o...

Organized Hematoma (OH) are benign hemorrhagic lesion that developed in the nasal sinuses. This tumor is a disease requires attention because it sometimes accompanied by bone destruction and can grow invasively into surrounding area. A 17-year-old Japanese male patient visited our hospital complaining of obstruction from about month ago. CT MRI imaging studies showed was confined to cavity.
