[A medical "odyssey" in a congenital unilateral diaphragm defect].

This is a case-report of an undiagnosed congenital defect (aplasia?) of the left diaphragm in a female adult, now aged 43 years. The woman was falsely diagnosed since her youth for cavernous tuberculosis and sent to a tuberculosis hospital for 17 months. Later on, the patient was thought to have a "tear" in the left lung (!) and treated for 9 months as an in-patient. Because of these wrong diagnoses dangerous therapeutic measures were performed. The retrospection this course seems to be rather unbelievable, however it should induce diagnosticians to serious reflections.

[Complex neurological investigations of space-occupying lesions in the spinal canal (author's transl)].

Problems of early diagnosis of space-occupying intraspinal lesions are discussed in relation to 335 patients on whom surgery had been carried out. Advances in neuroradiological methods are considered. The development of new contrast media has resulted in a reduction of the risk of invasive procedures and this should lead to diagnosis of space-occupying spinal lesions at a very early stage. It is now possible to diagnosis small tumours before they cause compression of the cord or of nerve roots.

[Post-operative lumbar myelogram. Morphology and indications for repeat examinations in patients with disc prolapse (author's transl)].

The morphology and indications for performing post-operative contrast examinations have been analysed in 131 myelograms. Leptomeningeal reactions and adhesions were found in varying degrees of severity in 34 to 75% of post-operative cases; it proved difficult to correlate this finding with the neurological features. The value of repeat myelograms is much reduced after surgery or after previous contrast examinations. It is probable that this is due in part to tissue changes resulting from the surgery or from a proliferative reaction induced by the contrast medium.

[Late meningeal changes after dimer-X-myelography in the absence of surgery (author's transl)].

Myelography with Amipaque was carried out in a group of 28 patients who had had previous Dimer-X-myelography, but no surgery. In 12 cases there was radiological evidence of a meningeal reaction. In all these cases there were chronic changes in the lumbar subarachnoid space. The original myelograms showed no evidence of adhesive changes in the root pouches. It was not possible to correlate the radiological findings of the meningeal changes with the severity or type of neurological diseases.

[Radiotherapy of the juvenile xanthogranuloma of the iris (author's transl)].

A report is given on an eight months old child with a juvenile xanthogranuloma of the iris and a secondary glaucoma. After radiotherapy with 6 X 0,5 Gy under conventional deep therapy conditions, a soon regression of the increased intraocular pressure was observed. In case of a juvenile xanthogranuloma of the iris, this secondary glaucoma represents in any case an acute danger to the eye, so it must be treated immediately. Radiotherapy has to be considered as the method of choice; it is also discussed with regard to the risk and the avoidance of a radiation cataract which, however, has to be tolerated in certain cases in order to prevent greater troubles.

[Pneumocephalus as sign of frontobasal skull fractures (author's transl)].

Pneumocephalus occurs as a complication after frontobasal skull fractures and points to a pressure difference between the extracranial and the intracranial space. From 8 cases observed during a period of 10 years, four case histories demonstrate the diagnostic principles and the surgical consequences. The diagnostic value of tomography of the frontal base for gaining an accurate picture of the topographic situation, and for proper application of intradural duraplasty, is underlined and characterized as a reliable procedure.

[The erysipelas as complication of a lymph oedema after therapy of mastocarcinomas (author's transl)].

1812 patients with mastocarcinomas were submitted to a combined therapy (surgery and radiotherapy); 34.2% of them developed an oedema. This inflammation is a complicating factor because it may increase the oedematous tendency. The authors discuss the correlations between a disturbed defluxion and an erysipelas tendency as well as the risks of a chronic stasis. These correlations necessitate an immediate and intensive treatment of the erysipelas.

[Embolization treatment of renal tumors (author's transl)].

Embolization of renal tumors is receiving importance. This method of interventional radiology was modified for our conditions and completed by special nuclear medical diagnostic. 86 embolization procedures were carried out in 80 patients with richly vascularized renal tumours. Nephrectomy was performed in 66 of these cases. Efficacy of our embolization technique was evaluated by nuclear medicine, intraoperative morphological findings and histological results. There were no complications in our series. We have found only in one patient a rejection of isotope labelled embolic material into peripheral arteries without clinical consequence.

Recognition of systemic portal shunts by lower extremity radionuclide venography.

Radionuclide venography was used to conduct 120 investigations of pelvic veins to find signs of systemic portal shunting. No signs of flow abnormalities were shown in the upper abdominal region in 80 patients with normal pelvic veins; 40 patients suffered from pelvic occlusions. Of these, 10 showed paraumbilical hot spots or liver demonstrations. These symptoms are assessed as signs of systemic portal shunts. The hemodynamic significance of this complication of pelvic vein thrombosis is discussed. It is supposed that a shunt from the systemic veins to the portal vein does not occur as infrequently as described in the literature. The radionuclide venography with 99mTc microspheres is a new and simple way to detect complication of pelvic vein occlusions.

[Intervention radiology for guided needle aspiration biopsy (author's transl)].

Aspiration of material on the basis of radiological examination is a well suited method of intervention radiology. This is demonstrated by lesions of the breast, thyroid gland, lungs, mediastinal masses, lymph nodes, skeleton and kidney. Intervention radiology represents the combination of tumour localization and guided cytological diagnosis without additional risks for the patient.

[Quality assurance of brachytherapy by means of interactive computer-assisted planning of the dose distribution using visual optimization (author's transl)].

Not earlier than with present generation of afterloading apparatuses,--efficient, reliable and appropriate for many purposes,--it was possible in brachytherapy to give up the previous impractical application techniques. Brachytherapy thus has found the widespread use it merits because of its good results. Additional utilization of a computer for the planning of dose distributions will guarantee the quality possible now in brachytherapy. To that end, a method of computer-assisted planning is described. It can be used for different application techniques. Further improvement of the results obtained till now is discussed in detail.

[Complications following cerebral angiography. Report on 4181 cerebral angiographies].

Complications of 4181 cerebral angiographies performed from 1973 to 1978 in 2365 patients were analysed. In 13,6% of the patients temporary complications could be observed. In 3,1% temporary neurologic-psychiatric complications occurred, most of them in patients of younger age and in the presence of diffuse cerebrovasuclar disease. There was a permanent damage in 0,21%.
