Bone scan abnormalities, especially rib lesions, are often confusing for physicians due to a high number of false-positive lesions. This study investigated risk factors that are associated with bone metastasis in 613 breast cancer patients with bone scan abnormalities. Significantly increased rates of bone metastasis were observed in patients with multiple lesions, large tumor sizes, and lymph ...

anatomy: middle cranial fossa mainly floored by sphenoidal bone and located post. to innominate bone or lesser wing and ant. to temporal bone. main foramens are located in deep part, bilateral to sellae are orbital fissures, optic canals, foramen rotundom, ovale and spinosum, foramen lacerum also meckle cave or trigeminal impression and carotid canal. this fossa is like a butterfly in shape. le...

We describe a patient with primary amyloidosis in whom multiple osteolytic lesions caused by amyloid bone tumours developed, and review the clinical features of the 18 cases with primary amyloidosis in whom destructive bone lesions have been reported. In contrast to amyloidosis associated with multiple myeloma, destructive lesions in the primary disease are mainly located to long bones; joint i...

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumor with a predilection for the bones of lower extremities and about one fourth of the tumors involve the foot.Radiologically, an eccentric lytic lesion with well defined margins is seen in the metaphysis of the bone. We hereby, report an 18 yr old young male who presented to Orthopedic Outpatient Department, JN Medical College, Aliga...

BACKGROUND This study characterized a novel rabbit model of subchondral bone bruise and investigated the intervening effect of calcitonin. METHODS Bone bruise was implemented via controlled free-fall counterpoise on the medial tibial subchondral bone of 5-month-old New Zealand rabbits, with 3, 2.5, or 2 Joules of energy. Subsequent subchondral bone bruise was characterized via magnetic resona...

To simulate periodontal and periapical lesions, bone cuts were made in mandibles from human cadavers, and the roentgenographic and visual appearances of the bone were compared. It is evident that inflammatory or tumorous lesions cannot be visualized if they are confined within the cancellous bone. However, if the lesions erode the junction area of the cortex and cancellous bone or perforate the...

Meningiomas are usually slow growing neoplasms that follow a benign clinical course. However, atypical and anaplastic meningiomas can show more aggressive behaviour have the potential to metastasise. The most common sites for metastases lung, spine, soft tissue, liver bone. Bone exceedingly rare. We report case of 70-year-old man with previous history recurrent meningioma (WHO grade III) pathol...

pathologic fractures of the jaw are usually associated with aggressive, destructive lesions or malignant lesions of the jaws. aneurysmal bone cysts (abc) of the jaws are benign lesions which normally do not cause destruction to such an extent. this article reports a relatively aggressive abc of the mandible in a 19 year-old male which destroyed the buccal and lingual cortices as well as the inf...
