This discussion concerns several developmental and acquired entities. The developmental entities referred to as the otodystrophies include otosclerosis, Paget's disease, fibrous dysplasia, and osteogenisis imperfecta. Otosyphilis and postradiation temporal bone changes are also included because of the overlapping imaging appearances.

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).

In addition to obliterative disease, which was easily diagnosed with multidirectional tomography, anterior and posterior foci of varying sizes can now also be visualized preoperatively. Active cochlear otosclerosis (otospongiosis) is diagnosed in the presence of foci of demineralization in the otic capsule. Diagnosis of these entities has been of great interest to our referring otologic surgeons.

CT scanning showed a soft-tissue mass in the hypotypanum. Angiographically, the mass was identified as a fenestrated or duplicated internal carotid artery associated with persistence of the stapedial artery. Embryologic considerations are discussed.

The computed tomographic appearance is that of a benign expansile soft tissue mass surrounded by a shell of bone, an appearance which is analogous to the typical changes of aneurysmal bone cyst in the extremities. Extension into adjacent bones and soft tissues can be demonstrated and thereby facilitate both preoperative planning and later follow-up for recurrence.

Twenty-six were diagnosed as having this disorder by CT evidence of abnormal bony excrescences at or adjacent to the oval window. The diagnosis was made upon examination of 1.5-mm-thick targeted sections obtained at 0.5-mm intervals in the axial projection. Coronal sections were also included. Sections were also evaluated for evidence of plaque formation elsewhere in the lateral wall of the labyrinth and for surgical obstacles such as an abnormally wide cochlear aqueduct, a high jugular vein, and a dehiscent facial nerve. It is concluded that fenestral otosclerosis may be accurately diagnosed with proper CT techniques.

One was associated with an additional fracture through the posterior arch on the opposite side in the region of the vertebral artery sulcus, and the other with an additional horizontal fracture through the anterior arch. Both patients were neurologically asymptomatic. Diagnosis was made by computed tomography.

The most frequent presentation is respiratory distress. There are 11 cases in the literature to date in which c linical and patholog ic aspects are emphasized, all with a paucity of radiologic features [1]. We are reporting a twelfth case, histologically proven, which includes computed tomographic (CT) demo nstration in ax ial, co ron al, and sagittal planes, conventional radiography, and poly tomography.

Clinical information about these entities is reviewed and technical considerations are discussed.

It affords exact anatomic localization of a mass and allows simultaneous examination of the contralateral gland and other regional structures of importance in salivary gland disease. Intravenous contrast medium enhancement is always utilized; however, concomitant sialography has never been necessary. Regional anatomy of the salivary glands with respect to computed tomography imaging and clinical material demonstrating its efficacy are presented. The neoplastic and nonneoplastic diseases affecting the salivary glands are reviewed.
