introduction: cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. the necessity for imaging in an uncomplicated case is controversial. this study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (hrct) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the...

We report a case of cavernous hemangioma originating in the maxillary sinus. This is an unusual location for hemangioma, and this case also had a rare presentation involving bone erosion. The substantial bone destruction and resultant widening of the right ostiomeatal complex made it difficult to differentiate this cavernous hemangioma from malignant epithelial tumors.

OBJECTIVE To investigate whether trabecular and cortical bone structure differ between patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA). So far, no study has performed a detailed comparative analysis of bone structure in patients with RA and PsA. METHODS 110 patients (60 RA, 50 PsA) received high-resolution peripheral quantitative CT of the distal radius. Demographic and ...

Proptosis of the left eye had developed in a 42-year-old woman for 2 months' duration. Roentgenogram studies showed a mass in the roof of the left orbit and bone erosion. An excisional biopsy confirmed the presence of an aneurysmal bone cyst. To the authors' knowledge, the patient is the oldest reported patient who has this uncommon orbital lesion.

Three cases of purely intracanalicular acoustic neuromas not causing bony erosion and/or enlargement of the internal acoustic canal walls diagnosed accurately by temporal bone CT examinations are presented. It is suggested that temporal bone CT scans done with the appropriate technique is a sufficient and

OBJECTIVES The aim of this study was to investigate bone changes in the condyle, articular eminence and glenoid fossa in relation to the position of the articular disc. METHODS 148 temporomandibular joints (TMJs) of 74 symptomatic patients who underwent MRI were evaluated. The position of the disc was classified as either normal (N), disc displacement with reduction (DDwR), disc displacement ...

INTRODUCTION Radiographic descriptions of gout have noted the tendency to hypertrophic bone changes. The aim of this study was to characterize the features of new bone formation (NBF) in gout, and to determine the relationship between NBF and other radiographic features of disease, particularly erosion and tophus. METHODS Paired plain radiographs (XR) and computed tomography (CT) scans of 798...

INTRODUCTION The aim of this study was to evaluate the condition of the ossicular chain in patients requiring surgery for cholesteatoma. MATERIALS AND METHODS In a retrospective analysis, the destruction of the individual and combined bony structures of the ear was described in 166 patients with cholesteatoma who went through surgery in our Otology Center between 2003 and 2009. RESULTS Tota...

OBJECTIVES The purpose of this work was to test whether normal peri-entheseal vascular anatomy at anterior and posterior cruciate ligaments (ACL and PCL) was associated with distribution of peri-entheseal bone erosion/bone marrow lesions (BMLs) in inflammatory arthritis (IA) and osteoarthritis (OA). METHODS Normal microanatomy was defined histologically in mice and by 3 T MRI and histology in...

Osteoclasts play a critical role in bone resorbing disorders such as osteoporosis, periodontitis, and rheumatoid arthritis. Therefore, discovery of agents capable of suppressing osteoclast differentiation may aid the development of a therapeutic access for the treatment of pathological bone loss. Ampelopsis brevipedunculata has been used as herbal folk medicine to treat liver diseases and infla...
