Osteoid osteoma in the base of the coracoid process of the scapula is very rare and diagnosis and treatment often is delayed. A lesion in this atypical location may seem surgically unreachable. This report is of a case of osteoid osteoma in the base of coracoid process in a 14-year-old female. The lesion had been diagnosed as a nontumorous condition and overlooked for four years. Computed tomog...

The case of a relatively frequent benign osteoblastic tumour, osteoid osteoma at an atypical site is presented. It was in a 20 year old man who attended the outpatient department of Aga Khan University Hospital, Karachi with pain in left groin since last 6 months which often occurred at night and was relieved by taking NSAIDs. X-ray failed to reveal the cause. CT scan showed central radiolucent...

BACKGROUND Osteoid osteoma is a painful benign osteogenic tumour for which the treatment objective is surgical resection of the nidus. The acetabular fossa is an uncommon site of involvement where surgical access can prove challenging. MATERIALS AND METHODS We report a case-series composed of five patients with osteoid osteoma of the acetabular fossa treated with percutaneous bone resection a...

Morphometric methods are commonly used in the diagnosis of diseases of bone. These may be divided into static and dynamic measurements. Static measurements include: (i) the proportion of trabecular surface which is resting, resorbing or covered by osteoid (by a perimeter intersect technique); (ii) the thickness of osteoid seams; and (iii) the proportion of the section occupied by mineralized bo...

INTRODUCTION Osteomas are asymptomatic and rare slow growing bony tumors in temporal bone, and should be taken into account in differential diagnosis of the osteolytic solitary skull lesions. Sometimes is associated with pain and functional loss. Only a few cases have been reported. CASE REPORT We describe a case of an osteoid osteoma of the temporal bone (mastoid) in a 31-year-old woman pres...

BACKGROUND AND OBJECTIVES Computed tomography (CT) measurements can distinguish between cortical and trabecular bone density in vivo. High-resolution CTs assess both bone volume and density in the same compartment, thus potentially yielding information regarding bone mineralization as well. The relationship between bone histomorphometric parameters of skeletal mineralization and bone density fr...

Osteoid osteoma is a benign bone tumor and accounts for 10% of benign tumors. Almost any bones can be involved but half of cases involving femur or tibia. Osteoid osteoma is a rare tumor of the scapula with only 18 reported cases in the literature. We presented a case of osteoid osteoma of the scapula in right shoulder in angle of coracoid and geloneid in a 34- year old woman. She had right rad...

Osteoid Osteoma is a little uncommon bony lesion. It rarely affects the scapula. Only a few cases are found in the literature. Even rarer is its occurrence at base of coracoids process. Osteoid osteoma of the base of coracoid process is a rare location. They may present simply as diffuse shoulder pain. Careful evaluation of the patient is important to diagnose this rare lesion. Clinical history...

Osteoid osteoma in periarticular lesions tends to have an unusual presentation that likely leads to a delayed or missed diagnosis compared with a typical osteoid osteoma in the metaphysis or diaphysis of the long bone. In cases that are unresponsive to conservative treatment, surgical interventions including en bloc resection, computed tomography-guided percutaneous treatment, and arthroscopic ...
