Non-vaterian duodenal adenomas: report of 24 cases and review of the literature.

Twenty-four cases of duodenal adenomas which did not originate at the ampulla of Vater are discussed. The radiographic and clinical features of these lesions are presented together with a review of 120 cases previously reported in the literature. The role of barium studies and endoscopy in the evaluation of these adenomas is emphasized. A diameter of more than 5 cm represents a criterion favoring malignant degeneration of such non-Vaterian adenomas.

Neurogenic tumors of the stomach. Report of 18 cases and review of the literature.

The general and radiologic features of neurogenic tumors of the stomach are reviewed in connection with 18 cases (16 benign and 2 malignant tumors). Such neurogenic tumors are rare in the stomach, representing less than 0.5% of all tumors. Solitary neurogenic tumors must be differentiated from those encountered during von Recklinghausen's disease. Radiological or endoscopic examination can generally determine the benign or malignant nature of solitary neurogenic tumors, which are essentially represented by schwannomas. Since these tumors are submucosal, a deep biopsy is imperative; furthermore, since such tumors are subject to hemorrhage, prior investigation by CT appears advisable to detect possible hypervascularization after injection of contrast material. For patients with von Recklinghausen's disease, a neurofibroma is usually diagnosed when faced with a digestive hemorrhage. Radiological exploration of the entire digestive tract appears essential to confirm the solitary nature of the gastric lesion and to be sure it is responsible for the clinical symptoms.

Ultrasonography of hepatic cavernous haemangiomas.

Cavernous haemangiomas, the most frequent benign tumours of the liver, are discussed by the authors in connection with 50 personal cases and surveillance of 35 solitary hyperechoic nodules less than 3 cm diam. without clinical or biological abnormalities. All the diagnostic images are reviewed but attention is focussed on ultrasound. All US patterns may be observed, but if the lesion is less than 3 cm, the echostructure is often hyperechoic and homogeneous. In view of their asymptomatic nature and the absence of risk of evolution for these small hyperechoic lesions, it appears legitimate to propose surveillance merely by US if there are no clinical symptoms and if liver function tests are normal.

[Adenocarcinoma of the small intestine. Current state of diagnosis and treatment. A study of 27 cases and a review of the literature].

On the basis of 27 personal cases of adenocarcinoma of the intestine and a review of the literature, the authors discuss present-day knowledge about this pathology from both radiologic and therapeutic viewpoints. This study, which excludes papillary tumors, reveals that, on a para-clinical level, barium follow-through examinations allow correct diagnosis in 85% of cases. Arteriography does not provide any special data, and more recent techniques such as ultrasound and C.T. do not appear suited for use in initial investigations. From a therapeutic standpoint, surgery is the only effective solution, but long-term survival had not increased for forty years. This rare form of cancer, with an especially insidious clinical course, has thus not benefited from recently introduced diagnostic and therapeutic technics.

Echography in hepatic angiomas.

All US patterns can be observed in hepatic angiomas; if the lesion is less than 3 cm, however, the echostructure is often hyperechoic and homogeneous.

[Echography in tumor pathology of the spleen: limitations and perspectives].

The authors review the symptomatology of splenic tumor pathologies in connection with 93 personal observations (71 non-Hodgkin lymphomas, 12 Hodgkin's disease, 6 metastases, 3 epidermoid cysts, 1 angioma). Nodular forms were observed in 31.2% of the cases reviewed. In most cases of lymphoma, the ultrasonographic finding was a homogeneous splenomegaly. The possibility of false negatives for splenic involvement in lymphomas when spleen volume is normal has led certain authors to suggest fine needle puncture of the spleen under ultrasonographic guidance. Such procedures are unnecessary if ultrasonography has detected an obvious lesion such as multinodular involvement of homogeneous splenomegaly. However, this moderately traumatic technique can provide valuable information until such time as ultrasonic tissue characterization has proven itself in vivo.

[Scanography and chemonucleolysis of herniated discs. Value and limitations in 20 cases].

Scanography explorations were conducted before and after chemonucleolysis in 20 patients with sciatica from herniated discs. The scanner can improve the selection of patients for this new type of medical treatment by detecting adverse factors: stenosed discs, excluded hernias, narrow canals, stenosis of the lateral recesses. The diagnostic precision of scanography can be demonstrated by comparison of results with those obtained by discography. Following chemonucleolysis, however, intravenous injection of a contrast medium and a high resolution programme are necessary to obtain specific information from scanography.

[Diagnostic reliability and economic profitability of 105 mm photography in digestive radiology].

A strict methodology using data-processing programmes was employed to compare diagnostic reliability and economic profitability of 105 mm photography and conventional radiography during 500 radiological examinations of the digestive tract. Films were evaluated twice on two separate occasions to determine correlation with predicted diagnosis and the amount of film exposed during the two investigational methods. Results demonstrated that a reliable diagnosis could be established with 105 mm photography (sensitivity: 97, 4 p. cent; specificity: 90 p. cent; diagnostic precision: 94 p. cent), that it was economically profitable (economy of 1 m2 of sensitized film surface at each examination), and that productivity was improved by the use of this method.

Leiomyoma and leiomyosarcoma of the digestive tract--a report of 45 cases and review of the literature.

The authors discuss the general and radiologic characteristics of leiomyomas and leiomyosarcomas, based on experience with forty-five cases involving the digestive tract and a review of over one thousand cases reported in the literature. Thirty-six leiomyomas (oesophagus 9, stomach 18, small intestine 9) and nine leiomyosarcomas (oesophagus 2, stomach 2, small intestine 4, colon 1) were observed and compared with reports from the literature. Leiomyomas of the oesophagus lend themselves to radiologic surveillance since there is no tendency for lesion degeneration in this location. Leiomyomas of the stomach are frequently asymptomatic and discovered following radiologic or endoscopic examination. With involvement of the small intestine, the most sensitive radiologic examination remains angiography, even though the information provided does not allow evaluation of the evolution of the tumour. Localization in the colon remains rare.

Selective embolization of symptomatic contralateral metastases in treatment of carcinoma of the kidney: report of 2 cases.

We report 2 cases of contralateral metastases secondary to renal carcinoma that had been treated with nephrectomy. Selective embolization was done in 1 case because hematuria did not respond to medical treatment. The lower two-thirds of the remaining kidney were embolized. The other patient presented with severe pain that was not relieved by medical treatment of radiotherapy and, therefore, selective embolization of the remaining kidney was performed. In both cases selective embolization conserved satisfactory renal function and nephrectomy was not necessary.

[The accuracy of angiography in the evaluation of benign renal tumours (author's transl)].

The authors review the literature regarding the angiography of three benign renal tumours: adenoma, angiomyolipoma and angioma. Renal adenomas area rare. Oncocytomas can be classified with papillary adenomas; they are fairly characteristic and can be diagnosed pre-operatively. The tubular, and particularly alveolar form cannot be distinguished angiographically from a carcinoma. Angiomyolipomas (hamartomas) occur in tuberous sclerosis or may be found alone. Angiography can first of all be an aid to topographic classification. Its isolated occurrence may cause difficulties in differentiation from a carcinoma. Certain angiographic signs may enable pre-operative diagnosis: the demonstration of aneurysmal arterial changes, linear course of tumour veins and the frequency of a peri-renal haematoma. Angiolipoma is the renal tumour which is most frequently complicated by pre-renal bleeding. Capillary, plexiform or cavernous angiomas are rare. If the first two are large enough (2 cm), their homogenous hypervascularisation may permit preoperative diagnosis. The diagnosis of cavernous angiomas is more difficult.
