Osteomas of the petrous temporal bone are rare and seldom symptomatic. This report describes an osteoma of the internal auditory canal, causing compression of the eighth nerve, leading to auditory and vestibular complaints. The symptoms were abolished by surgical decompression of the internal auditory canal and removal of the osteoma.

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.

Osteoid osteoma is a benign osteoblastic tumor usually seen in adolescent and young males. In the paediatric age group, since the history may be difficult to elicit, there are often problems in early diagnosis. The author reports an unusual presentation of osteoid osteoma in a ten-year-old girl, which could not be diagnosed by conventional X-rays and CT scan.

Osteoid osteoma is a benign tumor especially affecting young males generally treated with radiofrequency ablation. This is a non-invasive and safe procedure, major complications are very rare, most of them consisting in local skin burns. The present case shows a late subtrochanteric fracture in a young boy after CT guided termoablation of osteoid osteoma of proximal femur and short review of th...

Choroidal osteoma is a benign ossifying tumor of the choroid, consisting of mature bone tissue. It has been described to enlarge and evolve at varying rates over time. Here, we report and quantify the progression of a unilateral choroidal osteoma in a 7-year-old boy by fundus photography, and document tumor remodeling by spectral domain optical coherence tomography images.

Osteochondromas, occurring usually in the metaphyses of long bones, are among the most frequent benign musculoskeletal neoplasms and both their sporadic and hereditary variants have been studied extensively. Extraskeletal osteochondromas, however, are much less common. They have been shown to arise near joints or synovial spaces of feet, hands, or bursae. Herein, we present a very rare case of ...

Evolution of an osteoma may result in neurosensory detachment, deossification, and choroidal neovascularization (CNV). The authors report a rare case of choroidal osteoma with CNV associated with a deep non-conforming focal choroidal excavation. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:944-947.].

This report presents an extremely rare case of extraskeletal myxoid chondrosarcoma (EMC) arising from the clavicular periosteum. To the best of our knowledge, this may be the first detailed report of its clinicopathological findings. The patient was a 48-year-old man. Plain radiography and CT did not demonstrate any osteolytic lesion or periosteal reaction in the right clavicle. However, MRI sh...
