High resolution computed tomography in evaluation of the temporal bone.

High resolution computed tomography has completely replaced conventional multidirectional tomography in the evaluation of the temporal bone. Unprecedented detail is now available for evaluation of both middle ear and inner ear structures. A sampling of our experience in the evaluation of tubotympanic disease, otosclerosis, trauma, neoplastic disease, and congenital abnormalities is included in this publication. The state of the art in evaluation of sensorineural hearing loss is also illustrated.

High resolution computed tomography: Part 4, Evaluation of odontogenic lesions.

High resolution computed tomography (CT) has been a mainstay in the preoperative evaluation of odontogenic lesions. Unsurpassed bony detail is complemented by exquisite delineation of the soft tissue mass itself. Our experience with these lesions is presented. Selected illustrations are supplemented by pathologic review.

High-resolution computed tomography: Part 5. Evaluation of the temporomandibular joint.

High-resolution computed tomography (CT) is evolving as the most valuable radiographic study when detailed information about the status of the temporomandibular joint is needed. High-resolution CT is faster, less invasive, and in most cases much more accurate than other imaging modalities used in the past. Erosive, hypertrophic, and ankylosing arthropathies are illustrated, as are condylar dislocations secondary to acute trauma, chronic trauma, and neoplasm. A detailed discussion of the common problem of the anterior displaced meniscus is undertaken.

The foramen ovale. MR and CT correlation.

Six patients with lesions involving the foramen ovale are presented and analyzed. Anatomy, pathology and imaging of diseases occurring in the vicinity of the foramen ovale are reviewed. Computerized tomography (CT) and magnetic resonance imaging (MRI) are complimentary in the evaluation of pathology in this region. CT is better able to evaluate bony detail while MR imaging is useful in detailing the anatomical extent and tissue characteristics.

MR imaging of parotid mass lesions: attempts at histopathologic differentiation.

Thirty-four parotid lesions were examined with magnetic resonance imaging. The lesions were studied for a number of factors including size, T1 signal (relative to muscle), T2 signal (relative to CSF), homogeneity, associated adenopathy, associated abnormality of the deep cervical fascia, infiltration of subcutaneous fat, and seventh nerve involvement. Lesions histologically diagnosed as pleomorphic adenoma (benign mixed cell tumor) were predominantly homogeneous as well as smoothly marginated. Those diagnosed as papillary cystadenoma lymphomatosum (Warthin tumor), although equally well marginated, were strikingly heterogeneous, often with areas of hemorrhage. Malignancies and inflammatory masses were both associated with cervical lymphadenopathy; however, inflammatory masses demonstrated fascial thickening of the deep cervical fascia and infiltration of subcutaneous fat ("dirty" fat).
