Tumoren der Ceruminaldrüsen
Tumours originating from the ceruminous glands can be classified into five types: adenomas, adenocarcinomas, adenoid-cystic carcinomas, pleomorphic adenomas and mucoepidermoid carcinomas. The diagnosis is based on histological findings and can be quite difficult if the tumour status has to be determined. Classification into one of the five types of tumours may be facilitated at times by studying the clinical pattern. Three case reports are quoted as examples to illustrate that neoplasias originating from the ceruminous glands can assume considerable proportions and must be considered in differential diagnosis when assessing space-occupying growths in the soft tissue of the neck. Whereas pro…
Stellenwert bildgebender Verfahren in der Diagnostik des lumbalen Bandscheibenvorfalles
As a seeming law of nature the possibility of making use of various multiplanar sectional imaging techniques is accompanied by diagnostic exaggeration. Simple and cost effective procedures with low radiation dosage such as plain x-rays of the spine are being thrust into the background. Not seldom are patients referred to the spine surgeon with MRI or Cat scan at hand but lacking standard radiographs. As far as the assessment of intervertebral disc disease is concerned the combination of plain X-rays of the spine and computed tomography of the level in question turned out to be sufficient for indication of the operation in more than 90% of 450 patients after nucleotomie at the Orthopedic Uni…
Digital Subtraction Angiography in Staging Renal Cell Carcinoma: Comparison with Computerized Tomography and Hlstopathology
Digital subtraction angiography was compared to computerized tomography and histopathological findings for staging renal cell carcinoma in 24 patients. Injection of contrast material through a 16 gauge angiocatheter into the femoral vein provided digital subtraction cavography, digital subtraction arteriography and excretory urography during 1 investigation. Computerized tomography established the diagnosis in all patients, while digital subtraction angiography showed all angiographic signs of renal cell carcinoma in 14 (58 per cent). T staging was correct on computerized tomography in 18 patients and on digital subtraction angiography in 16. Absence or presence of venous involvement was in…
