Eighteen patients with fractures of the pelvis were examined by computer tomography. The results were compared with those of conventional radiological diagnosis. ⋯ It was also possible to demonstrate injuries to pelvic, abdominal and retroperitoneal organs and injuries to other regions of the body, such as the skull and thorax. Haematomas could be directly demonstrated and additional information, useful for plannng surgery, was obtained.

Case Reports
[The value of cranial computed tomography in posterior fossa epidermoids and dermoids (author's transl)].
Report on posterior fossa epidermoids and dermoids (3 in the cerebellopontine angle, 1 in the region of the fourth ventricle). Computed tomographic aspects are related with other neuroradiological findings. Differential diagnosis of these mass lesions is discussed in detail, especially of low density and (rarely occuring) high density epidermoids.

Lung metastases from carcinoma of the prostate usually manifest themselves as radiologically diffuse lymphangitis carcinomatosa. Unlike the pathological findings, a radiological diagnosis is relatively uncommon. ⋯ In over 10% lung metastases were found, mostly in the form of lymphangitis carcinomatosa. In view of the bad prognostic significance and therapeutic implications of lymphangitis carcinomatosa, it is important to bear this in mind and to look for it radiologically.

The jet phenomenon seen during entry of urine into the bladder is illustrated by the urograms of a number of patients. Its diagnostic significance is discussed. Experimental models and theoretical considerations have shown that the jet is determined by the kinetic impulse; for a 1:10 mixture of contrastmedium and water, the jet is visible at all jet diameters and jet speeds at the orifice provided flow at the centre of the jet has fallen to about 0.073 m/s. Transferring these findings to man, and bearing in mind the functional and anatomical peculiarities and pressure differences between the lower ureter and the bladder, it becomes apparent that this phenomen can be produced under physiological conditions.

Idiopathic disseminated pulmonary ossification is a rarely recognised condition in which small pieces of marrow containing bone are found in the interstitial tissues of the lungs. The case reported here is unique in showing combination with myositis ossificans circumscripta. The extent of the lung changes was also unusual. The clinical, radiological and histological findings are compared.
