[Possibilities of short-time tomosynthesis].

Short-term tomosynthesis enables continuous analysis of structures which appear interesting. The results of short-term tomosynthesis were compared with those of plain roentgenography and conventional tomography. Short-term tomosynthesis appears as an alternative to spot-film radiography and as a complement to tomography in the analysis of spatially limited regions. It facilitates orientation in space and free projection of oblique structures. Good results were obtained in examinations of the pyramids (auditory canal and mandibular joint), the paranasal sinuses, the cervical vertebral column, the extremities and their joints. Examination of soft tissues was usually not very promising in view of the conditions under which tomosynthesis was performed. The same applied likewise to the infusion cholecystocholangiogram and the infusion urogram. Technical improvements will certainly bring about an extension of the uses of this method.

[Computerized tomogram following pancreatic resection].

After partial or total pancreatic resection displacement of abdominal organs, alterated bile- and food passage as well as pathological signs may be observed. In this serie scar-tissue was no problem in the differential diagnosis. Tumor recurrency can be demonstrated quite easily if follow-up examinations are available. Artifacts may influence the interpretation and can be the cause of a false negative reading.

[Cerebral cysticercosis in the computer tomogram].

Cysticercosis cerebralis can occur as a parenchymatous, subarachnoidal, ventricular or mixed type. One further form can be identified besides these clearly defined types. X-ray morphology in the computer tomogram, as well as the histopathological findings, suggest that this special form may be designated as "vasculitis cysticercotica" or "encephalopathia inflammatorica cysticercotia". Our own results indicate that this disease is widespread among the populations in developing and threshold countries; in our own patient material (Northern Mexico), the rate of incidence was more than 9%.

[Computer tomography following splenectomy].

After splenectomy a displacement of the left kidney, stomach, colon and pancreas can be observed. The scar tissue regularly contains fat. The differentiation between haematoma and empyema may be difficult in certain cases. Large holes and those containing liquid and air may be attributed wrongly to the stomach or colon. Additional investigations are often necessary. Differential diagnosis between a residual spleen and a tumour recurrency may be difficult, if there is no follow-up examination.

[Roentgen morphology after vagotomy].

Vagotomy is often followed by changes in the shape and motoric function of the stomach which usually return to normal in the course of a few months. The morphological changes which are typical for the different surgical techniques are described on the basis of references and the authors' own findings. X-ray examination contributes towards distinguishing regular postoperative changes from complications. The necessary long-term follow-ups to discover any possible recurrence of ulcers should be supplemented by gastroscopy.

[Tuberculosis peritonitis in infants].

Examination of a peritonitis tuberculosa in three children, each of one year of age, resulted in an x-ray film morphology of the type known in peritonitis tuberculosa in adults. The identification of extended loops of constant localization is a pointer in this direction. Diagnosis becomes even more probable if the clinical pattern is also considered or if there are changes in the lung.

[Parathyroid gland cancer and hyperparathyroidism].

A patient with an endocrine-active carcinoma of the parathyroid gland was observed. The typical signs of hyperthyroidism could be seen in the skeletal system. Symptoms of bone and kidney diseases dominated the clinical picture. The symptomatology corresponded to a subchronic primary hyperparathyroidism.

[Intestinal perforation in juvenile abdominal typhoid].

Eight of 19 children with typhus abdominalis who were between 4 and 12 years of age, showed perforation of the intestine. The terminal ileum was always the site of the perforation. Besides the clearly visualized air, meteorism of the small intestine was always seen. In individual cases, segments of the small intestine were seen in close proximity to each other, or an ileus developed. The x-ray film in typhus abdominalis in childhood shows the same signs as an adult x-ray. A characteristic feature of the perforation is its localization in the terminal ileum and the time at which it occurs, namely, between the end of the 2nd and the end of the 4th week of the diseased condition.

[Intestinal obstruction caused by Ascaris].

A worm-conglomerate in cases of ascariasis may cause an intestinal obstruction. The worms can be demonstrated as irregular oblong shadows or nodular thickenings. Level formation in the intestine must not be found because of filling intestinal loops with worms.

[Atlas arch aplasia].

A bilateral aplasia of the dorsal arches of the atlas with persisting tuberculum posterius has been observed by the authors. Since the patient had suffered a severe cranio-cerebral trauma, it became necessary to exclude a possible fracture by differential diagnosis. This was possible by means of CT and conventional x-ray diagnosis. According to the classification of dorsal atlas arch aplasia by von Torklus and Gehle (1975) into 6 types, the diagnosis was, in the case under report, Keller's type of aplasia of the arch of the atlas.
