BACKGROUND Osteoid osteomas are benign bone-forming tumors characterized by local inflammation and pain. They are also characterized by a small osteolytic lesion (nidus). Spondylolysis is a defect of the pars interarticularis, which may lead to stress fractures, and is a common cause of low back pain in adolescence. Osteoid osteoma occurs predominantly in the posterior elements of the spine. Ma...

Periosteal osteoid osteoma is extremely rare. The diagnosis is not always clear. We report a case of periosteal osteoid osteoma arising from the posterior surface of the right distal femur in a 21-year-old woman. After careful evaluation and excisional biopsy, histological examination confirmed the diagnosis of osteoid osteoma, showing the nidus, surrounding osteosclerosis, and catarrhal synovi...

Surgical excision is the traditional treatment for osteoid osteoma. However, the complexity of the foot anatomy makes a satisfactory outcome challenging. Difficulty in localizing the lesion intraoperatively may result in either incomplete tumor resection or excessive bone loss. To date, no published report has described the use of three-dimensional printing in the surgical treatment of osteoid ...

Osteoid osteoma and osteoblastoma are rare primary bone tumors that usually do not arise in the spine. Histologically, osteoid osteoma and osteoblastoma are similar, containing osteoblasts that produce osteoid and woven bone. Osteoblastoma, however, is larger, tends to be more aggressive, and can undergo malignant transformation, whereas osteoid osteoma is small, benign, and self-limited. With ...

An intraarticular osteoid osteoma of the knee is uncommon, and its treatment is challenging. The authors present a case of arthroscopic excision of an intraarticular osteoid osteoma in the distal femur, which was accessible through the knee joint. After confirming the nidus of the osteoid osteoma by computed tomography, the lesion was completely removed arthroscopically. The patient reported co...

Osteoid osteoma is a benign skeletal neoplasm composed of osteoid and woven bone. The majority of the lesions arise in the cortex of long bones. Osteoid osteoma of the spine is a rare primary spine tumor and those located at the thoracal spine are even rarer. The usual treatment involves complete resection, including the nidus, or alternatively radiofrequency percutaneous ablation is performed....

STUDY DESIGN Case report and systematic review of the literature. OBJECTIVE To describe a rare case of remodeling of the cervical facet joint after the microendoscopic resection of an osteoid osteoma. SUMMARY OF BACKGROUND DATA Osteoid osteoma, the third most common benign bone tumor, is often treated by image-guided percutaneous removal of the nidus. However, percutaneous resection poses t...

INTRODUCTION Osteoid osteoma is a benign tumor that usually occurs in the long bones of young adults. Its symptoms can be diverse depending on the location of the tumor and especially difficult to diagnose when occurring in an atypical location. Osteoid osteoma arising in the sacrum is extremely rare, and here, we present a case that was treated successfully in a minimally invasive fashion unde...

Background Osteoid osteoma is a bone-producing lesion frequently localized in long bones. The most common presenting symptom is pain with nocturnal exacerbation, responsive to nonsteroidal anti-inflammatory drugs [1]. Minimally invasive treatment options have become the standard of care for osteoid osteoma and at present radiofrequency ablation is the treatment of choice [2]. Only one prelimina...

Osteoid osteoma is a rare entity in the tarsal bones especially in children. High degree of suspicion is needed for early diagnosis and delay in diagnosis can cause significant disability. Radiofrequency ablation (RFA) is safe, minimally invasive method especially to treat juxta-articular and inaccessible lesions. Atypical Osteoid osteoma can present with clinical features similar to that monoa...
