[Arterial hypertension and horseshoe kidney during Von Recklinghausen's disease. Angiographic study and review of the literature (author's transl)].

Angiographic studies in a young girl aged 16 years who developed arterial hypertension during the course of Von Recklinghausen's disease, demonstrated the presence of an obliterated renal artery in a horseshoe kidney. The distal arterial segment was revascularized by two homolateral ureteral arteries. A full review of the literature revealed 30 cases of renal artery lesions for which angiography had been carried out in young people with neurofibromatosis. This demonstrates the low incidence of obliterative lesions (4 cases throughout the world) which are always associated with collateral vascularization. It was not possible to apply the usual surgical treatment in our case because of the associated horseshoe kidney.

[Angiomyolipomas (hamartomas) of the kidney. Radiological study apropos of 2 cases. Review of the literature].

Two patients with renal angiomyolipomas studied angiographically are reported:--A case of tuberous sclerosis with bilateral multiple lesions, renal, hepatic and adrenal;--An isolated lesion whose preoperative diagnosis allowed the excision of the tumor. A review of the literature from 1965 to 1977 identified 242 cases of which 177 were isolated angiomyolipomas. There were 54 cases associated with tuberous sclerosis and one with von Hippel-Lindau disease. The radiologic and especially the angiographic signs are illustrated, the hemorrhagic risks are stressed, and the diagnostic features of fetal renal hamartoma are described.

[Voluminous hypernephroma of intermittent development. Diagnostic difficulties (author's transl)].

The authors report a case of cancer of the kidney of intermittent development for which nephro-urotomography was negative. They stress the interest of: --preliminary echotomography in patients with palpable masses in the left hypochondrium; --pharmaco-angiography for improved visualization of masses that are only weakly opaque; --a rapid infusion technique, proposed by various authors, which appears to be the most appropriate for the study of this type of mass which is mainly intermittent in its development.

[Congenital malformations of the inferior vena cava. Embryological, anatomical and radiological study (author's transl)].

Congenital malformations of the inferior vena cava are characterized by their diversity which is related to the complexity of the embryological development of this vessel. The authors review the embryogenesis and origin of the different segments of the inferior vena cava and describe the various types of malformation, including the causative embryological abnormality, ther frequency, possible clinical repercussions, and radiological aspects. Phlebocavography is essential for the identification of the various types of abnormality. Five different types of malformation are reported. Three of these are relatively rare (left inferior vena vaca, congenital membrane of the inferior vena cava, absence of the hepatic segment with continuation of the isolated azygos segment).

[Inferior mesenteric arteriovenous fistula of congenital origin. A report on one case and review of the published literature (author's transl)].

A fourth case of inferior mesenteric arteriovenous fistula of congenital origin is described by the authors, who also review the general characteristics of mesenteric (or portal) arteriovenous fistulae. Early clinical signs are hemorrhage from the digestive tract and chronic anemia. Endoscopy and barium X-rays are normal, and angiography is the only means of diagnosis. Surgical treatment is essential because of the risk of hemorrhages and portal hypertension.

[Radiology of tumours of the region of the ampulla of Vater (author's transl)].

On the basis of 18 personal cases, the authors discuss the different radiological appearances of tumours of the ampulla of Vater region. After a review of the histopathological aspects, they attempt to separate the respective indications for the various endoscopic and radiological studies possible, stressing the importance of duodenoscopy. They give an illustrated classification of the different appearances seen.

Pancreatic Castleman disease: CT findings.

Computed tomography findings in a case of pancreatic localization of Castleman disease are presented correlated with histological findings. This is the second observation in the literature of pancreatic involvement with an unusual histological form.

Ultrasound and computed tomographic findings in pancreatic metastases.

This is a retrospective study of a series of seven patients with pancreatic metastases studied by ultrasonography and computed tomography. They were detected during tumor staging, or in the follow-up period of over 10 years of patients with advanced known malignancy. Lesions were multiple in two patients and solitary in five; solid in six cases and cystic in one. Clinically, four cases were asymptomatic and three cases presented with jaundice or epigastric pain. Ultrasonography and computed tomography findings were non-specific. Consequently it was not possible to differentiate solitary metastases from primary solid adenocarcinoma and cystadenocarcinoma of the pancreas. In these cases, computed tomography- or ultrasonography-guided biopsies had to be performed to obtain histological proof. However, multiple lesions discovered in a patient with a known malignancy can be assumed to be due to metastases.

The value of MRI in the study of spinal extradural arachnoid cysts.

Two cases of extradural arachnoid cyst in the spinal canal were diagnosed by magnetic resonance imaging (MRI). MRI correctly characterized the extradural location of the cysts as well as the cyst contents as CSF, thus establishing the diagnosis. MRI may be of predictive value in the postoperative prognosis.

[Imaging of hepatoma. Review of 50 cases].

The authors present 50 cases of hepatoma involving 32 cirrhotic and 18 healthy livers. Only 6 cases were amenable to exeresis completed by peripheral (4 cases) or intra-arterial (2 cases) chemotherapy. In addition to a semeiological study, the usefulness of various imaging techniques (ultrasound, CT, angiography) is discussed. Ultrasound (50 cases), the basic examination, is often sufficient for diagnosis (28 cases of puncture under ultrasound guidance); in certain cases it suffices to rule out surgery (multiple forms, vascular involvement). CT scans (40 cases) are obtained in different manners depending on whether the aim is to detect a hepatoma not seen on sonograms (as in the case of a high alpha-foetoproteinemia) or to obtain more precise anatomical data for an already discovered lesion. At present, angiography (13 cases) appears reserved for cases in which the other two techniques do not reveal any contraindications for surgery.
