SUMMARY We report the CT and MR findings in a patient with malignant peripheral nerve sheath tumor in the parapharyngeal space who had neither a family history nor stigmata of neurofibromatosis. A high-resolution CT scan of the temporal bone revealed bony erosion and widening of both the foramen ovale and the bony portion of the eustachian tube. A temporal bone MR image showed an intensely enha...

Introduction: Squamous Cell Carcinoma (SCC) is the most common head and neck malignancy. To decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. The main purpose of this prospective study is to compare the diagnostic value of Computed Tomography (CT) and Magnetic Resonance Im-aging (MRI) in oral SCC and its lymph ...

Intracranial hematoma rarely presents between two dural layers of pachimeninges. Here, we present a case of an interdural hematoma with similar appearance to an epidural hematoma. A 51-year-old man presented with a left temporal contusion following a motor vehicle accident. After craniotomy and contusion removal, the post-operative CT scan showed a parietal intracranial hematoma...

Introduction: Accurate evaluation of femoral and tibial torsion is essential for children or adult with legs deformity, becuse incorrect legs morphogenesis can lead to pathological situation. CT scan is commonly used for the measurement of skeletal bone parameters. But, disability in imaging from standing and sitting posture and absorb dose of patients are deficits of this meth...

OBJECTIVE To assess the sensitivity of the routine computed tomographic (CT) scan of the temporal bone coupled to a virtual endoscopy, with density threshold variation, in detecting small fistulas in human temporal bone specimens. DESIGN Single-blind, before-after trial. SETTING This study was carried out in a research laboratory in collaboration with a radiology department. PATIENTS Five...

OBJECTIVES To describe a cadaveric temporal bone model of labyrinthitis ossificans and investigate the utility of intraoperative cone-beam computed tomography (CBCT) in the facilitating cochlear implantation. DESIGN Cadaveric temporal bone study. METHODS Five cadaveric heads had cement introduced into the 10 cochleas. CBCT and a conventional CT scan were compared to assess the extent of coc...

BACKGROUND Cochlear implantation has become a mainstream treatment option for patients with severe to profound sensorineural hearing loss. During cochlear implant, there are key surgical steps which are influenced by anatomical variations between each patient. The aim of this study is to determine if there are potential predictors of difficulties that may be encountered during the cortical mast...

From an engineering background, it is often believed that the human anatomy has already been fully described. Radiology has greatly contributed to understand the inside of the human body without surgical intervention. Despite great advances in clinical CT scanning, image quality is still related to a limited amount X-ray exposure for the patient safety. This limitation prevents fine anatomical ...

OBJECTIVE The aim of this work was to report an unusual case of multiple soft tissue metastases of osteosarcoma detected using bone scan and confirmed by CT scan. CLINICAL PRESENTATION AND INTERVENTION A 15-year-old patient with a history of osteogenic sarcoma presented with fatigue and loss of appetite in addition to a painless swelling of the distal left lower extremity. Bone scan and chest...

BACKGROUND Accurate radiological assessment of the anatomical features of the temporal bone is crucial to prevent damage to vital elements in this area during surgery. Knowing the approximate location of specific temporal bone related landmarks in advance is very important for planning surgery. OBJECTIVES This study compared findings from computed tomography images with those observed directl...
