background many clinical and experimental studies have been done to analyze the anatomical and functional aspects of the internal auditory canal (iac) in human beings since there are great inter-individual variability and structural variations that may occur regarding the other adjacent structures. objectives the purpose of this study was to characterize the morphology of the internal auditory ...

introduction: ewing’s sarcoma is the second most common primary malignant tumor of bone found in children after osteosarcoma. it accounts for 4–9% of primary malignant bone tumors and it affects bones of the skull or face in only 1–4% of cases. hence it rarely affects the head and neck. subject and method: in this case report, we describe a case of primary ewing's sarcoma occurring in the tempo...

A rare, non-neoplastic lesion involving the 1st metatarsal bone in a 5-year-old female is described. Radiographically it presented as a cystic lesion of the whole of the metatarsal. Fine needle aspiration cytology showed it to be a benign giant cell lesion. The tumour was excised en bloc and the metatarsal replaced by a free fibular graft of adequate length. Histopathological examination confir...

conclusions our study shows in terms of figures that measurements of features of the temporal bone made from spiral ct scan images and those directly obtained during surgery are similar to an adequate extent. results twenty cases were included. in the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly differe...

background: otalgia and bell’s palsy are rare manifestations of metastasis and the most common presentation of an inflammatory process in the temporal bone. case presentation: this article explains a 34-year-old woman with breast cancer who presented with cranial nerve palsy symptoms. the 7th and 8th cranial nerves were involved in the metastatic phase and then hoarseness was added to her sympt...

Background: Chondroblastoma of the spine is a very rare condition. To the best of our knowledge, fewer than 30 cases have been reported in the world literature. Material and methods: The authors describe here a rare spinal localization with an uncommon evolution and make a review of the cases of spinal chondroblastoma reported in the literature. Results: We report the case of a patient with chr...

Epiphyseal tumours in young patients are a diagnostic challenge, largely due to their rarity. The differential diagnosis for a lytic lesion with well-defined margins at the epiphysis of a long bone in a young patient should fundamentally include three lesions typically found at the epiphysis: chondroblastoma, giant-cell tumour of bone and clear cell chondrosarcoma. Other conditions to consider ...
