Intra- and periarticular osteoid osteoma: Percutaneous destruction and alcoholisation.
نویسندگان
چکیده
Intra- or periarticular osteoid osteoma (00) is uncommon, and therefore a diagnostic challenge. Symptoms are: chronic synovitis, decreased range of motion, joint effusion, and joint contracture. Radiographically, the classical perifocal sclerotic margin is often absent, which leads to a significant delay in diagnosis. The authors retrospectively studied 50 cases of intra- and peri-articular OO, treated with percutaneous destruction and alcoholisation. The mean follow-up period was 8.7 years (range, 1 to 15 years). The diagnosis was only made after +/-14 months (range, 8 to 18 months), due to atypical symptoms (nightly pain absent in 38%) and uselessness of plain radiographs (in 100%). CT-scan, contrast enhanced MRI and bone scan brought the solution. The technique was successful in 48 out of 50 cases (96%): incomplete excision occurred in 2 patients. The diagnosis of intra- or periarticular OO should be considered in case of unexplained joint pain where conservative treatment is inefficient.

Percutaneous laser photocoagulation of osteoid osteoma: Assessment of treatment in nine cases
ABSTRACT Background: Osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. In the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. In this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ILP) for treatment of osteoid osteoma in Iranian patients. Materials and Methods: In this case s...

Osteoid osteomas are self-limiting, benign, bone-forming neoplasms.1,2 First described by Jaffe in 1935,3 these lesions are common and account for 10 to 12% of all benign bone tumors. These lesions almost always occur in patients younger than 30 years, are more common in males than females (approximately 2 to 1 ratio), and over 50% of the time are foundwithin the metaphysis or diaphysis of long...

Osteoid osteoma in periarticular lesions tends to have an unusual presentation that likely leads to a delayed or missed diagnosis compared with a typical osteoid osteoma in the metaphysis or diaphysis of the long bone. In cases that are unresponsive to conservative treatment, surgical interventions including en bloc resection, computed tomography-guided percutaneous treatment, and arthroscopic ...
متن کاملPercutaneous thermoablation of osteoid osteoma--a case study.
Osteoid osteoma has been traditionally treated by curettage and en bloc resection. These methods are now being replaced by low-invasive techniques. We present the description of a percutaneous thermoablation of a femoral neck osteoid osteoma performed under CT guidance in a 22-year-old female patient.
