The problem of possible neonformation of lymphatic nodes following lymphadecetomy was studied by means of computer tography in 45 patients with malignant tumours of the tests and 5 women who had been subjected to radical hysterectomy (Wertheim's operation). In addition, the problem of visualisation of the lymphatic nodes via computer tomography is discussed on the basis of a few examples.

3 angiomyolipomas were found in 8,500 CT examinations of the abdomen. The diagnosis was established preoperatively by both computed tomography and sonography. The densitometrically negative density values that are considered to be principal signs in computed tomography, must however be refuted by us. In all cases under investigation we found density values above 40 HU.

The exact measurement of the transverse diameters of the bony spinal canal is not yet possible due to the limitations of the CT-systems presently available. Therefore, these measurements have to be made on conventional radiographs.

The article reports on a male patient of 72 years of age suffering from rhinoliquorrhoea caused by meningoencephalocele. This disease pattern is in itself very rare, but in the case presented here it assumes a highly unique character by the concomitant clinical picture, namely, a combination with mucocele of the frontal sinus and by the case history (rhinoliquorrhoea without trauma and without meningitis).

Case report on a case of pelvic lipomatosis, the 21. case published in the world literature. The typical radiographic findings, such as deformity of the urinary bladder and the abnormal course of the sigma, were seen. Computed tomography confirms the diagnosis.

Imaging of the vault of the cranium via CT must be considered as an additional examination. It is possible to assess the CT image already stored during examination of the brain, without additionally exposing the patient, merely by changing position and breadth of the window. In our opinion, primary indication for CT of the vault of the cranium exists only if diagnosis based on survey remains doubtful. However, examination will always be combined with a representation of the individual strata of the brain. Our studies have also shown that in many cases CT assessment of the vault of the cranium necessarily also involves comparison with the surveys.

The article reports on the value of the analysis of the histogram in computed tomography in carcinoma of the pancreas. This additional examination possibility is critically reviewed and analysed. Evidently this method is useful as an additional examination method which can throw light on possible malignancy of a process in case of doubt.

This article emphasises that computer tomography is suitable for disclosing occult destructions in the region of the vertebral column. On the other hand, computer tomography is of great importance for determining the extent of destructions which are already manifest, and any possible spreading of a pathological process in the soft parts to the vertebral column.

Sulphonyle ureas used in the oral treatment of diabetes occupy albumen-binding capacity. Hepatotropic contrast media therefore have difficulty with protein binding and renal excretion is increased. The proportion excreted through the kidneys has been determined in 50 diabetic patients on oral treatment. Demonstration of contrast in the urine was done radiologically, qualitative measurements by a subtraction method. As a control, the same group of patients were examined, having been taken off suphonyle ureas, as well as a group of 50 diabetic patients treated with insulin. While under medication, heteroptropic excretion rose on average to 55% and in some cases to 80%. This results in definite reduction of contrast filling of the biliary tree, occasionally to the extent of preventing a diagnosis. Displacement of sulphonyle urea by contrast was not observed.
