We report a painless osteoid osteoma of the inner ear in an elderly woman presenting with hearing loss, tinnitus, and vertigo. CT showed a heterogeneous mass containing calcifications involving the posterior labyrinth, which heterogeneously enhanced on postcontrast MR images. Osteoid osteoma should be included in the differential diagnosis of an osteolytic petrous bone lesion with central calci...

Osteoid osteoma has been traditionally treated by curettage and en bloc resection. These methods are now being replaced by low-invasive techniques. We present the description of a percutaneous thermoablation of a femoral neck osteoid osteoma performed under CT guidance in a 22-year-old female patient.

We present a case of an intra-articular osteoid osteoma in the knee that was mistaken for a painful fabella syndrome after unsuccessful knee arthroscopy for the treatment of postero-lateral knee pain. In this case both the initial clinical presentation and the imaging proved to be deceiving. The diagnosis of intra-articular osteoid osteoma was considered only once typical clinical features appe...

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...

Osteoid osteoma of the foot can be difficult to diagnose, clinical presentation may mimicking other local pathologies leading a considerable delay in diagnosis. We report an exceptional localization osteoid second metatarsal 30-year-old patient, expressed for 3 years by metatarsalgia, with no and radiological architecture defect foot. After discovering nidus, patient underwent surgical excision...

BACKGROUND Osteoid osteoma accounts for approximately 10% of all benign bone tumors. The most common sites of osteoid osteoma are the subcortical shaft and metaphyses of long bones, but any other skeletal bone site can be involved. The acetabulum is a rare site according to past reports. This site presents challenges to optimal management because it is anatomically difficult to approach, and be...

Hands, especially lunatum, are involved very rarely with osteoid osteoma. This report presents an osteoid osteoma of the lunatum, which was previously misdiagnosed as Kienböck's disease and had undergone surgery. Magnetic resonance imaging may lead the clinician to misdiagnose because of the excessive bone edema around the carpus. The operation should be planned according to radiography and com...

A case of intracortical haemangioma in the tibial diaphysis is reported. The radiological and macroscopic features were identical with osteoid osteoma. In view of this similarity, haemangiomata, despite their rarity at this site, must be considered in the differential diagnosis of osteoid osteoma.

RATIONALE Lumbar osteoid osteoma has a low incidence, which could easily lead to scoliosis. PATIENT CONCERNS Scoliosis secondary to lumbar osteoid osteoma could be easily misdiagnosed when patients do not complain of obvious symptoms. DIAGNOSES We reported a case of a 9-year-old boy with back deformity that was firstly diagnosed with scoliosis at the local hospital. After prescribed with or...

BACKGROUND An osteoid osteoma is a benign bone tumor that tends to be <1 cm in size. The tumor is characterized by night-time pain that may be relieved by aspirin or other non-steroidal anti-inflammatory drugs. Osteoid osteoma can be treated with various conservative and surgical methods, but these have some risks and difficulties. The purpose of the present study was to present an alternative ...
