INTRODUCTION We present a case report highlighting the unusual location and atypical imaging characteristics of an osteoid osteoma in the juxta-articular region of the femoral head, and treatment of the condition with radiofrequency ablation. This treatment option is low in both risk and morbidity and is therefore the best option in lesions that are difficult to access surgically because of the...

Osteoid osteoma: a case for conservative management SIR, Osteoid osteoma is a benign bone tumour with a predilection for long bones, occurring predominantly in children and young adults. The conventional paradigm holds that, once suspected on clinical and radiological grounds, surgical excision is necessary, both for its cure and to exclude other, more sinister pathologies. We report the case o...

Three cases of osteoid osteoma and one of benign osteoblastoma in children are described. The main complaint was severe pain which was worse at night; it was relieved by aspirin or other analgesics. The diagnosis was made on clinical and radiological grounds and was confirmed on histological examination of the central nidus removed at operation. The pain was relieved in the patients with osteoi...

Osteoid osteoma is a benign bone tumour; its main symptom is pain, which is sometimes resistant to analgesic or anti-inflammatory medication. The surgical treatment consists of en bloc excision or curettage of the lesion. Several alternative methods have been proposed, among which CT guided-percutaneous radiofrequency ablation. We report on ten patients who were diagnosed clinically and radiolo...

A 24-year-old man presented with a stress fracture over his left tibia following an infantry training 6 years ago. X-rays of his left tibia revealed a stress fracture and bone scan showed marked tracer uptake at the fracture. He was treated conservatively but his pain persisted since then. Five years later, X-rays and histological examination confirmed the diagnosis of osteoid osteoma. The stre...

The osteoid osteoma is a benign bone tumour that usually presents with nocturnal pain in young adults, relieved by rest and anti-inflammatories. It can affect any bone; however, their occurrence is rare in the acromion. The authors describe a case of osteoid osteoma located in the acromion, with symptoms that simulated acromion claviculararthrosis. The diagnosis was made by CT scan and treatmen...

Radiol Bras. 2015 Jul/Ago;48(4):V Osteoid osteoma is the third most common benign neoplasm of bone, occurring predominantly in young, male patients. In most of cases, the patients report inflammatory-like pain that worsens at night and is alleviated with the use of nonsteroidal anti-inflammatory drugs. Osteoid osteoma is classically characterized at conventional radiography or computed tomograp...
