[Accidental finding of a giant retroperitoneal lipoma in a traumatic rupture of the renal parenchyma]. / Zufallsbefund eines retroperitonealen Riesenlipoms bei traumatischer Nierenparenchymruptur.

With a rate of 0.1-3% of all tumour cases primary retroperitoneal neoplasms are very rare. Malignant tumours predominate. Preoperative radiological clarification as regards tumour status is very unsafe unless there are indications of infiltrating growth and metastases. In some cases, computed tomography can supply pointers to the kind of the tumour.

[Case examples of rare locations of aneurysms]. / Fallbeispiele seltener Aneurysmalokalisationen.

We describe four cases of rare aneurysm localisations, one case of an aneurysm of the hepatic artery, two cases of aneurysms of the superior mesenteric artery and its branches and, as an extreme rarity, one case of an aneurysm of the superior gluteal artery (only three known cases up to now). All cases were documented by arteriography/DSA, ultrasonography and computed tomography. We refer to incidence, aetiology, symptomatology, and possible complications as indicated by literature.

[Advantages of computerized tomography diagnosis in acetabular fractures]. / Vorteile der Computertomographie-Diagnostik bei Acetabulumfrakturen.

There is a comparison of conventional radiographs and computed tomography in 23 patients presenting acetabular fracture. Four patients were treated conservatively because of their CT-findings. The result was successful. Surgery took place in 19 patients. Intraoperative findings verified CT-diagnosis in all cases, while diagnosis with conventional radiographs in 3 projections had to be corrected in 8 of 19 cases. Advantages of CT in acetabular fracture: 1. always manageable, 2. correct topography of fracture, 3. discovery of small especially intraarticular bone fragments, 4. judgement of congruity of the joint, 5. clear decision of management. 6. definite surgical approach. In conclusion, the CT-scanning of acetabular fractures is preferable for correct classification as opposed to conventional radiographs; if only plain X-ray films are available CT-scanning is to be required.

[On the aetiology of malignant pericardial mesothelioma (author's transl)]. / Beitrag zur Atiologie der malignen Perikardmesotheliome.

Two cases of malignant pericardial mesothelioma are described. Morphologically they corresponded to the epithelial or fibrous type, respectively. In one patient, an old-metal dealer, an increased number of asbestos bodies were found in the lung parenchyma and phase-microscopy demonstrated increased asbestos needles in the lung parenchyma. Since, beyond a certain fibre size, asbestos can induce bronchial carcinoma as well as pleural or peritoneal mesothelioma, it is likely that the pericardial mesothelioma had a similar aetiology.
