• Osteoid osteoma is a benign bone tumor that usually presents in children and young adults characterized by local pain which is worse at night; occasionally the pain is referred to a site distant from the actual lesion. • Osteoid osteoma of the scapula should be considered in the differential diagnosis of neuralgic amyotrophy due to shared clinical features of pain, weakness, and atrophy aroun...

Osteoid osteoma of the calcaneus is rare and frequently misdiagnosed as arthritis because of similar symptoms. In addition, radiographic findings may be nonspecific, and magnetic resonance imaging (MRI) may show a bone marrow edema and changes in adjacent soft tissue. A 19-year-old man presented with a 6-month history of persistent pain and swelling in the left hind foot; diagnostic computed to...

intraepiphyseal location of an osteoid osteoma is extremely rare with few cases reported in the literature. they are often present with various atypical and nonspecific clinical features. synovitis of adjacent joint is common and along with chronic inflammation could be misinterpreted as rheumatoid arthritis. initial plain radiographs are often not diagnostic and further radiologic evaluation w...

INTRODUCTION Osteoid osteoma is a benign tumor of the growing skeleton. It presents with pain, which is usually worse at night. The radiographic features consist of a central oval or round nidus surrounded first by a radiolucent area followed by another area of sclerotic bone. In the hand, osteoid osteoma is more commonly located in the phalanges and carpal bones. The metacarpals are the least ...

Osteoid osteoma is a small benign bone tumor usually affects adolescents and young adults. Although this tumor mainly affects the shafts of long bones there have been several reports of subperiosteal and intramedullary involvement .Complete surgical excision is the classic treatment of choice for patients with osteoid osteoma. Despite the small size of the tumor, the operative procedure for its...

The prevalence of back pain during childhood is 50%; in 22% of these cases, a specific diagnosis can be found. Osteoid osteoma is a rare benign tumor that occursonly in 20% of cases and involves the spine. The aim of this report is to explain an atypical case of lumbar osteoid osteoma with significant neurologic deficit at a very young age. A five-year-old boy was presented with refractory pain...

osteoid osteoma is a benign bone tumor that when located on the base of the coracoids process of the scapula is very rare and diagnosis and treatment is often delayed because of its rarity. almost any bone can be involved, but half of cases involve the femur or tibia. the radiologic features of osteoid osteoma are well known, but these tumors may present with unusual features and be easily misd...

BACKGROUND Osteoid osteoma is a benign bone neoplasm which is seen in the long bones of appendicular skeleton. It is rarely seen in the cranium. Skull base osteoid osteoma is extremely rare and has been anecdotally reported. CASE PRESENTATION The authors report a case of a large osteoid osteoma of the ethmoid with intraorbital and intracranial extension in a 33 year old male patient. He prese...

A 6-year-old boy was referred by his general practitioner to our hospital for further investigation of chronic hindfoot pain. An MRI scan was performed. Sagittal IR images revealed bone marrow edema in the anterosuperior portion of the talus (‘talar neck’) with adjacent soft tissue edema (Fig. A). Axial T1 SE depicted a rounded structure with peripheral hypo-intensity within this region of bone...

We present a case of a 53-year-old woman with recurrent intra-articular osteoid osteoma of the hip 6 months after initial treatment with percutaneous radiofrequency ablation. En bloc surgical excision of the osteoid osteoma and prophylactic internal fixation for impending stress fracture was performed. The patient is pain free, has returned to normal function and there is no sign of recurrence ...
