Osteoid osteomas are most likely to occur in the talar neck and can be classified as cortical, cancellous, or subperiosteal according to the position of the tumor nidus. However, cases located on the bearing surface of the talus are rare. Herein, the patient presented with an osteoid osteoma on the bearing surface of the talus and achieved good curative effects with arthroscopic resection associated with autologous iliac crest graft.

We present the case of an intra-articular osteoid osteoma at the femoral trochlea. Intra-articular osteoid osteoma can present a diagnostic challenge both clinically and with imaging because it presents differently from the classic cortical osteoid osteoma. Given the lesion's proximity to overlying cartilage, the patient underwent resection of the lesion with osteochondral autograft transplantation at the surgical defect. A comprehensive literature review and discussion of intra-articular osteoma will be provided...

Osteoid osteoma is a benign primary bone tumor. This tumor is relatively frequent, accounting for 12% of all benign bone tumors and about 2-3% of all bone tumors. We report a new case of osteoid osteoma confirmed histologically. A 30-year old patient was referred for evaluation of chronic ankle pain. Front and lateral radiographs of the ankle showed a heterogeneous lesion located in the neck of the talus without soft tissue abnormalities. The CT scan of the ankle showed a nodular, hypodense lesion located in the neck of the talus with a limited osteosclerotic reaction...

BACKGROUND: Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. CASE REPORT: Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery and excision of the osteoma by the Caldwell-Luc procedure. CONCLUSION: Unique coexistence of two different entities in the maxillary sinus is most likely due to pediatric facial trauma...

Osteoid Osteoma is benign bone forming tumor which commonly occurs in long bones of lower limb. Presence of these rare tumors in the distal phalanx of the digits of the hand is considered a rare phenomenon. In hand, they usually present as chronic pain, swelling, nail enlargement and increase in size of digit. Diagnosis is challenging with clinical examination and usual imaging modalities and often confused with glomus tumor, enchondroma, infection, trauma and rheumatic disease. Surgical excision of the tumor, if present in hand, is the treatment of choice that aids in coming to the exact diagnosis too...

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 tomography and MRI analyses revealed lesions suggesting an intra-articular osteoid osteoma of the calcaneus. Initial MRI did not show specific findings...

Intracranial osteomas completely unrelated to osseous tissues are extremely rare. In the present study, the case of a 40-year-old female who presented with persistent headache is reported. Computed tomography (CT) and bone window CT revealed an ossified lesion in the frontal area. Fast imaging employing steady-state acquisition (FIESTA)/CT venography fusion imaging demonstrated that the mass was located just below the superior sagittal sinus and cortical veins, and had adhered partially to these veins. Surgery achieved complete tumor removal with preservation of the cortical veins and superior sagittal sinus...

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months...

Osteoid osteoma, a rare benign osteoblastic tumor first described by Jaffe in 1935, is characterized as a small but painful lesion that mostly affects younger people. Usually benign and harmless, osteomas are removed for pain or esthetic reasons.Piezoelectric surgery is also increasingly being used effectively in major and minor osseous oral and maxillofacial surgeries, in delicate areas. It is used regularly for various procedures, including sinus lift procedures, bone graft harvesting, osteogenic distraction, ridge expansion, inferior alveolar nerve decompression and lateralization, cyst removal, dental extraction, and impacted tooth removal...
