Osteoid osteoma radiology

Introduction. Osteoid osteoma is a benign bone tumor that occurs most frequently in men and boys between 7 and 25 years old ().Most patients experience pain that worsens at night and is promptly relieved by the administration of salicylates ().The term nidus, which was described as the core or niduslike focus by Jaffe in 1953 (), refers to the tumor itself and is composed of bone. Osteomas are benign mature bony growths, seen almost exclusively in bones formed in membrane (e.g. skull). Terminology When they arise from bone they may be referred to as a homoplastic osteoma, and when they arise in soft tissue they may be..

Bone - Osteoid osteoma. This website is intended for pathologists and laboratory personnel, who understand that medical information is imperfect and must be interpreted using reasonable medical judgment Osteoid osteomas are benign bone lesions with classic characteristics on plain film, MRI and CT. They are also a very common exam case and are worth rehearsing in a slick way. The clinical presentation of osteoid osteomas is also rather classic and should be mentioned to the examiner Plain X-Ray, MRI and CT findings together with the clinical presentation are highly suggestive of osteoid osteoma. Plain X-Ray, MRI and CT findings together with the clinical presentation are highly suggestive of osteoid osteoma. Plain X-Ray, MRI and CT findings together with the clinical presentation are highly suggestive of osteoid osteoma One hundred surgically proved cases of osteoid osteoma were reviewed, with emphasis on the modalities used in the detection, diagnosis, and localization of this benign tumor. These included plain radiography, tomography, radionuclide imaging, and angiography. Diagnosis may require all of these techniques

Osteoid osteoma is a benign bone-forming neoplasm, first described by Jaffe in 1935 [].Approximately 10% of all benign bone tumors are osteoid osteomas [2, 3].It is found most frequently in the second to third decade of life, and there is a pronounced male predominance (2:1 male-to-female predilection) Osteoid osteoma is a benign skeletal neoplasm of unknown etiology that is composed of osteoid and woven bone. Radiography is the initial examination of choice and may be the only examination required. CT is used for precise localization of the nidus and may be used for guiding percutaneous ablation

Author information: (1)Department of Radiology and Biomedical Imaging, 400 Parnassus Ave, A-367, San Francisco, CA 94143; School of Medicine, 400 Parnassus Ave, A-367, San. Osteoid osteoma is a small benign bone tumor. It is rarely located on the acetabulum. CT is the gold standard for diagnosis. The use of MRI is justified if there is doubt in the diagnosis especially in unusual localizations, such as juxta articular or intramedullar forms. Treatment of osteoid osteoma is exclusively surgical Osteoid Osteoma. Osteoid osteoma was first described in 1935 by Jaffe, who also coined the term. 4 It is the most commonly seen benign bone-forming lesion, accounting for 10% to 12% of all benign bone tumors and 3% of all primary bone tu mors. 1,5 This lesion most commonly occurs in persons aged 5 to 25 years, with a male:female ratio of 2:1. 6.

Osteoid Osteoma Localization: It prevalently occurs in the appendicular skeleton, while it is rare in the trunk, with the exception of the spine (mostly localized in the posterior arch). In the limbs, it prevails in the proximal femur, but it is also common in the other long bones where it is more often diaphyseal or metadiaphyseal BACKGROUND: Osteoid osteoma is a benign and painful musculoskeletal tumour that usually affects children. Current standard treatment is CT-guided radiofrequency ablation, a minimally invasive percutaneous procedure, with clinical success rates ranging between 85% and 98%

Once an osteoid osteoma is formed there is a large amount of reactive bone formed around them and also tend to form new bone material called the osteoid bone. This osteoid bone along with the tumor forms the center of the tumor and can be clearly seen on radiological imaging like x-rays Osteoid osteoma is an infrequent but important cause of musculoskeletal pain, however it can be difficult to make an early diagnosis, particularly when these lesions present with neurological signs and symptoms. In such cases the diagnosis of osteoid osteoma requires an accurate clinical history and most importantly an awareness of the possibility of the diagnosis Osteoid Osteoma. Osteoid osteoma is a small benign (noncancerous) tumour that arises from the osteoblast (bone building cells). It is found in the long bones of legs, usually in the thighbones but it can also occur in the bones of the hands and lower part of the spine.

IAOO is less common (10-13% of osteoid osteomas), involving commonly the hip and very rarely the elbow The benign bone lesions — osteoma, osteoid osteoma, and osteoblastoma — are characterized as bone-forming because tumor cells produce osteoid or mature bone. Osteoma is a slow-growing lesion most commonly seen in the paranasal sinuses and in the calvaria. When it occurs in the long bones, it is invariably juxtacortical and may need to be differentiated from, among others, parosteal.

Osteoid osteoma is a benign bone lesion of uncertain origin that accounts for approximately 10% of all benign bone tumors [].When intraarticular, the classic radiolucent nidus is often overlooked at radiography because reactive sclerosis may be minimal or absent [2,3,4].The subtle radiographic appearance combined with a nonspecific clinical presentation often leads to delay of diagnosis and. Osteoid osteoma is a small benign bone tumor that is commonly located (in 20% of cases) in the upper third of the femur [1, 2].It is usually found in young patients who present with pain that worsens at night and that may be relieved by the use of nonsteroidal antiinflammatory drugs [].However, deviations from this typical presentation are common, especially in cases of intraarticular osteoid. Osteoid osteoma is a benign skeletal neoplasm characterised by nocturnal pain that is relieved dramatically by salicylates. Brodie's abscess is the main differential diagnosis for osteoid osteoma.
