[Value of angiography in hemangiopericytomas].

Haemangiopericytoma is a rare type of tumour which mostly develops in the soft parts. The article reports on the manifestations of one tumour each in the thigh and pelvis. The angiogram shows displacement of the major arteries, the tumour-supplying vessels penetrate into the growth by means of one or several peduncles, and intensive coloration takes place during the parenchyma phase. However, the "typical angiographic image" was seen in one of the two cases only.

[Ioxaglic acid, a contrast medium with low osmolarity in clinical use].

The article reports on the clinical use of sodium and meglumine ioxaglate/Hexabrix, an angiographic contrast medium of low osmolarity. Due to this low osmolarity, favourable experiences were collected in 287 angiographic examinations. Special attention was paid to the question to what extent the contrast medium was responsible for pain, and it was found that Hexabrix definitely causes less pain than the tri-iodated conventional contrast media. During the examination no pain was registered which would have been indicated verbally or by means of movements as involuntary reactions to pain. In arteriography Hexabrix is definitely superior to the conventional contrast media.

[A case of congenital cystic intrahepatic bile duct dilatation (Caroli syndrome) treated with hepato-lobectomy].

The authors report a successful hepatolobectomy of Caroli's disease (segmentally dilatated intrahepatic bile ducts). They also give a survey of congenital and acquired bile duct dilatations, with a view to differential diagnosis and medical treatment. When Caroli's disease is suspected, echography and ERCP can be a valuable diagnostic aid. The definitive cure i. e. the elimination of the anatomical basis of recidive cholangitis, can only be achieved by the resection of the liver containing the dilated intrahepatic bile ducts. Postoperative administration of antibiotics and anticholelithic drugs can help the liver to full recovery.

Symptomless renal tumours diagnosed from their metastases.

After a brief review of renal tumours diagnosed on the basis of metastases, two cases are described in which subcutaneous formations believed to be lipomas were metastases of symptomless hypernephromas. One case was diagnosed early on basis of the histological finding. The primary tumour could be localized only by angiography. After nephrectomy and resection of the contralateral rib and pleura, the patient was free of symptoms for one year. In the subsequent year a pathologic subtrochanteric fracture called attention to a new metastasis. After laminar osteosynthesis function of the hip and knee joints was satisfactory and so has been the general condition ever since the first operation now for three years. In the second case, the knot assumed to be a lipoma was removed but no histological examination was carried out. These experiences have induced the authors to call attention to the importance of histological examination of apparently banal lesions and to the considerable survival which can be achieved in these patients.
