Radiofrequency ablation (RFA) therapy is recognised as a safe and effective treatment option for osteoid osteoma. This case report describes a 27-year-old man who underwent computed tomography (CT)-guided percutaneous RFA for a femoral osteoid osteoma, which was diagnosed based on his clinical presentation and CT findings. The patient developed worsening symptoms complicated by osteomyelitis af...

An 18-year-old girl presented with an osteoid osteoma in the ulnar side of the cortex of the distal radius extending into the distal radioulnar joint. The osteoid osteoma was removed from the distal radius at surgery. The patient’s symptoms were dramatically improved the day after surgery. A high concentration of prostaglandin E2 (PGE2) was seen in the joint and surrounding soft tissues, and cy...

We report herein the case of an 18-year-old man who underwent endoscopic resection for an osteoid osteoma in the seventh cervical facet joint. The patient had experienced right neck pain for approximately one year, but no neurological abnormalities were noted. Cervical magnetic resonance imaging suggested an osteoid osteoma in the superior articular process of the seventh cervical vertebra. The...

PURPOSE To report on 14 patients with osteoid osteomas treated by computed tomography-guided radiofrequency ablation. METHODS Nine males and 5 females aged 13 to 45 (mean, 25) years with osteoid osteomas were included. The proximal tibia was the commonest site involved. A bipolar 18-gauge radiofrequency probe with a 9- mm active tip was used. A 4.5-mm hollow drill was introduced into the nidu...

Renal mixed tumor characterized by the absence of nephrogenic blastema and the presence of predominant osteoid-producing osteoblast-like cells occurred in the kidney of a 6-month-old, hybrid, female pig. At the post-mortem examination, the tumor was found as a calcified grayish-white mass at the cranial end of the left kidney. Histologically the tumor consisted of 3 growth areas of poorly diffe...

background: fluoride (f−) is a trace element that is incorporated into bone mineral during bone formation. this study assessed the effect of increasing fluoride doses on the bone formation and microarchitecture on the femur of rats by histological, and histometrical methods. materials and methods: a total of 16 rats was divided into one group of control and three groups of animals that received...

Osteoid osteoma is type of benign bone tumor, characterized by a well-demarcated core with a typical size of <1 cm and by a distinctive surrounding zone of reactive bone formation. The tumor can occur anywhere in the cortex or medulla of the skeleton. However, the lesion usually affects the long bones of the lower extremities. The present study describes two cases of osteoid osteomas located in...

A case of cervical osteoid osteoma is reported, with a brief account of the diagnosis and treatment of these lesions. Cervical osteoid osteoma is rare but its pattern of presentation varies little and it should therefore be possible to suspect it on clinical grounds alone. Bone scanning is now regarded as more efficient than radiography in identifying the lesion but X-ray tomography will normal...

Osteoid osteomas are small, benign bone tumors most commonly located in the proximal femur or tibia. The classic presentation is localized pain increasing in severity at night, and relieved by the use of anti-inflammatory medications. In a young athlete complaining of foot pain, many conditions should be included in the differential diagnosis. A case of osteoid osteoma of the os calcis in a tee...

we present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. the patient has been suffering from the disease for two years without a certain diagnosis. the radiographies of elbow did not reveal the pathology but further ct scan and mri studies demonstrated the tumor. the en block resection of the tumor resolved the pain immediat...
