Terminology. Primary tumors originate in the spine or spinal cord, and metastatic or secondary tumors result It arises from red marrow due to the monoclonal proliferation of plasma cells and manifests in a wide range of radiographic abnormalities. Metastases most frequently go to lungs and bones in equal proportions. Exostoses are defined as benign growths of bone extending outwards from the surface of a bone. The condition is characterized by tenderness and painful swelling of the anterior (front) chest wall at the costochondral (rib to cartilage), sternocostal (cartilage to sternum), or sternoclavicular (clavicle If the spine is affected, they may present with symptoms related to nerve root compression 1,3. According to the WHO classification of soft tissue and bone tumors (5 th edition) the term "liposclerosing myxofibrous tumor" is no longer recommended and instead, fibrous dysplasia is preferred..

Clinical presentation If malignant transformation occurs (~1% in solitary osteochondromas and ~5-25% with hereditary multiple exostoses ) then the resultant chondrosarcoma is usually of low grade (67-85% of cases), and surgery is usually curative (70-90%) 3,5 .

The tumor is named after James Stephen Ewing (1866-1943), an American pathologist, who first described his eponymous tumor in 1920 8,11. Fibrous dysplasia is a disorder where normal bone and marrow is replaced with fibrous tissue, resulting in formation of bone that is weak and prone to expansion.As a result, most complications result from fracture, deformity, functional impairment, and pain. Cystic changes might be present, especially in older lesions. Radiographic features Plain radiograph. Associations. Epidemiology Osteomas are more common in middle-aged men 1,3. Macroscopic appearance. On the left a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. 2 m. Primary Osseous Extradural Neoplasms. Skull vault osteomas are benign primary bone lesions that are commonly incidentally discovered.

Tietze syndrome is a benign inflammation of one or more of the costal cartilages.It was first described in 1921 by German surgeon Alexander Tietze and was subsequently named after him. chondroblastoma. osteofibrous dysplasia. medial implant offset after total hip arthroplasty. Radiographs are typically normal, although cystic change and sclerosis may be seen within the lesser trochanter or ischial tuberosity. Eosinophilic granuloma: benign lesions, rare in adults, that affect bones and may cause a collapse of the vertebrae; they are more common in the mid-back.. Epidural lipomatosis: excessive growth of fat inside the epidural space.. Synovial cyst: a fluid-filled sac that typically forms in the lumbar spine (lower back) around the vertebral joints, usually from Periosteal osteosarcoma is a form of surface osteosarcoma. fibrosarcoma. It may be typically seen as a rather benign-appearing osteolytic bone lesion with well-defined margins. History and etymology. They are less common than paranasal sinus or mandibular osteomas. There are no officially recognized subtypes 1. Complications include: pathologic fracture; nerve compression syndrome; spinal canal stenosis Aneurysmal bone cysts commonly present with pain and swelling. pathological fracture. endocrinopathy: precocious puberty; polyostotic fibrous dysplasia: more severe than in sporadic cases cutaneous pigmentation: coast of Maine 'caf au lait' spots In the spine located in the body or in both body and arch. Macroscopically, lesions are intramedullary, well-circumscribed, and often expansile with abnormal whitish or tannish-grey color and gritty consistency. Trinity Health, a comprehensive healthcare system based in Minot, ND, proudly serves the North Dakota, Eastern Montana, and Saskatchewan region. On rare occasions, this is the result of a pathologic fracture. When in the spine they are a classic cause of painful scoliosis, concave on the side of the lesion. Fairbank's disease or multiple epiphyseal dysplasia (MED) is a rare genetic disorder (dominant form: 1 in 10,000 births) that affects the growing ends of bones.Long bones normally elongate by expansion of cartilage in the growth plate (epiphyseal plate) near their ends.As it expands outward from the growth plate, the cartilage mineralizes and hardens to become bone (ossification). The Spine Journal, the official journal of the North American Spine Society, is an international and multidisciplinary journal that publishes original, peer-reviewed articles on research and treatment related to the spine and spine care, including basic science and clinical investigations.. valgus osteotomy. solitary enchondroma; Ollier disease; Maffucci syndrome; Distribution.

The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents.The Journal publishes original work based on standards of excellence and expert review. The radiological report should include a description of the following 13: location and size; tumor margins and transition zone; relation to the growth plate; degree of sclerosis; Treatment and prognosis. intertrochanteric fracture. Bone islands may occur anywhere in the skeleton, although there is some predilection for the pelvis, long bones, spine, and ribs. Non-ossifying fibromas are considered as leave alone or do not touch lesions. Disease occurs along a broad clinical spectrum ranging from asymptomatic, incidental lesions, to severe disabling disease. Liposclerosing myxofibrous tumors can occur in a wide age range with a peak in the 4 th decade of life 2-4.Men and women seem to be equally long bones: 45% (the reason is that the cartilage is more abundant in the long, tubular bones) femur: 20-35%; tibia: 5%; upper limb (especially proximal humerus): 10-20% osteopoikilosis: multiple bone islands; Radiographic features Plain radiograph / CT. Enostoses are commonly seen as small round or oval foci of homogeneously dense bone within the medullary space. Osteomas are commonly found in patients undergoing imaging of the sinuses, appearing in up to 3% of CT examinations of the paranasal sinuses 1.They are most frequently diagnosed in 20-50 years olds, and there is a male predilection (M:F = 1.5-2.6:1) 1. Soft tissue swelling may occur (see case 4) and if close to a growth plate, accelerated growth may be evident 2, presumably related to hyperaemia. Trevor disease. relation to the growth plate. Radiology Research; Doctors who treat this condition. Soft tissue swelling may occur (see case 4) and if close to a growth plate, accelerated growth may be evident 2, presumably related to hyperemia. This typical presentation is seen in over 75% of cases 2. Exostoses can cause chronic pain ranging from mild to debilitatingly severe, depending on the shape, size, and location of the lesion. Describing a bone lesion is an essential skill for the radiologist, used to form an accurate differential diagnosis for neoplastic entities, and occasionally non-neoplastic.In addition to patient demographics, the radiographic features of a bone lesion are often the primary determinant of non-histological diagnosis. 7 m.

Osteochondroma is the most common benign bony tumor, accounting for 30% (range 20-50%) of all benign bony tumors and 10% to 15% of both benign and malignant bony tumors combined. A spinal tumor is an abnormal mass of tissue within or surrounding the spinal cord and/or spinal column.These cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. The osteochondroma can be locally resected for cosmetic or mechanical reasons. This typical presentation is seen in over 75% of cases 2. spine and pelvis: 12%; ribs: 2.5%; Radiographic features Plain radiograph.
