AI Article Synopsis
- The talus is an uncommon location for osteoid osteoma, and tumors found near joints exhibit unique clinical and pathological characteristics.
- Three cases of subperiosteal osteoid osteoma in patients aged 15, 17, and 25 highlight the importance of recognizing the disease for accurate diagnosis, as it can be tricky due to subtle changes in symptoms and imaging.
- Diagnostic methods like bone scans, radiographic exams, and CT scans play critical roles in identifying the tumor, while sequential angioscintigraphy helps suggest the lesion's nature, ultimately confirmed by macroscopic and histological analysis.
Article Abstract
The talus is a rare site of predilection for osteoid osteoma. This tumor, in its juxta-articular position, presents particular clinical and pathological features. Three cases of subperiosteal osteoid osteoma are discussed in patients aged 15, 17 and 25 years. In diagnosis, a basic role is played by awareness of the disease, which must lead to the use of bone scan, indicating the site of the pathological lesion, which may be difficult to determine because of subtle radiographic modifications, and particularly because of long-term changes in the symptoms. Radiographic examination (standard x-rays, enlarged x-rays), often characterises and reinforces what is diagnostically suspected. CAT clearly shows the features and type of osteoid osteoma in relation to the adjacent structures. Sequential angioscintigraphy, based on the captation curve of the radionuclide, may suggest the nature of the lesion, subsequently confirmed by the macroscopic picture and histological examination.

Femur osteoid osteoma in children: are there location-dependent differences in MRI findings?
Pediatr Radiol
January 2025
Department of Radiology, Children's Hospital of Philadelphia, 3401 Civic Center Blvd, Philadelphia, PA, 19104, USA.
Background: Osteoid osteomas are most commonly found in the femur and preferentially affect the pediatric population. Magnetic resonance imaging (MRI) findings of femoral osteoid osteomas are not well described.
Objective: To systematically characterize pretreatment MRI findings of clinically confirmed femur osteoid osteomas in children and determine location-dependent differences.

Osteoarthritis of the knee is a common cause of pain, functional disability, and reduced quality of life in the elderly. Despite its prevalence, there are limited currently available noninvasive treatment options. MRI-guided focused ultrasound (MRgFUS) is a noninvasive thermal ablation method which is used in a spectrum of musculoskeletal conditions.

Background: Electromagnetic navigation (EMN) is an advanced technology increasingly utilized in orthopedic surgery for its ability to provide real-time intraoperative guidance. Its application in spinal surgery is evolving rapidly, particularly for complex cases like tumor lesions. Spinal osteoblastomas, characterized by their benign nature, primarily affect the posterior elements of the spine.

Osteoid osteoma is a benign bone tumor commonly affecting young individuals, with a rare occurrence in older adults. It typically presents with night pain relieved by nonsteroidal anti-inflammatory drugs and is characterized radiographically by a small, radiolucent nidus surrounded by reactive sclerosis. We present a 70-year-old female patient with persistent right hip pain, initially diagnosed as arthritis, who underwent total hip arthroplasty.

Introduction And Importance: Osteoid osteoma (OO) is a common benign bone tumor, mostly affecting young adults. Since it often develops in long bones, OO is rarely considered as a cause of chronic shoulder pain.
Case Presentation: We treated an 8-year-old boy with ongoing shoulder pain that was worse at night but improved with NSAIDs.
