[Sonographic detection and the clinical significance of the left retroaortal renal vein].

A retro-aortal left renal vein can be expected in 12.2% of the patients, as anatomical examinations show; in 8,9% of the cases, this presents as a circum -aortal venous ring, whereas in 3.3% it occurs as an isolated V. renalis retroaortalis sin. The sonographic image of this deviation from the standard and its clinical relevance are demonstrated.

[Microcystic pancreas adenoma].

The microcystic adenoma of the pancreas is a very rare benign pancreatic tumour. This tumour, which is usually large and grows slowly, results in displacement and compression of the adjacent organs. Angiography reveals hypervascularisation. The characteristic structure of the tumour can be recognized both in the sonogram and in the computer tomogram.

Primary osteoliposarcoma of bone.

Radiologic and pathoanatomic findings in two patients with the very rate primary osteoliposarcoma of bone are reported. In one case, there was a manifestation on the left femoral shaft which led to pathologic fracture. Amputation of the femur was followed by a 2.5-year tumor-free interval. In the second case, there was a manifestation in the region of the right upper part of the ilium. After radiation and cytostatic therapy, pronounced intratumoral ossifications occurred and the patient's condition was good up to exitus lethalis 3 years after diagnosis. Osteoliposarcoma thus shows a markedly more favorable prognosis than the osteosarcoma and rather corresponds to that of a liposarcoma. Typical clinical and radiologic symptoms are lacking.
