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.

Objectives: To evaluate the influence of clinical and procedural factors, particularly the thickness of reactive sclerosis, on clinical outcome of MR-guided high-intensity focused ultrasound (MR-HIFU) for the treatment of symptomatic osteoid osteomas (OO) of the extremities.
Materials And Methods: 18 consecutive patients (median age 19.5y) with symptomatic OO of the extremities eligible for MR-HIFU were enrolled in this ongoing prospective study (German Clinical Trials Register; nr.

Osteoid osteoma (OO), a benign bone-forming tumor estimated to account for 3% of all primary bone tumors, rarely occurs in the finger. This case report presents an unusual instance of osteoid osteoma in the finger of a 15-year-old male patient. The lesion was discovered following an initial patient visit for left middle finger pain and swelling for one year without any identifiable injuries.

Background And Aim: Osteoid osteoma (Oo) and osteoblastoma (Ob) are rare primary bone tumors with a higher prevalence in the second decade of life. Treatment can be conservative, but in cases of spinal location, resective surgery is of great importance but may be challenging.
Material And Methods: We report four pediatric cases of Oo and Ob managed in our unit, with different locations at the level of the cervical spine.
