[Aneurysm of an aberrant right subclavian artery. Original contribution of x-ray computed tomography and digital subtraction angiography].

An original aspect of a case of atheromatous aneurysm of an aberrant right subclavian artery was the evaluation of the complementary diagnostic value of CT scan and intravenous digital subtraction angiography imaging. The vascular anomaly was clearly identified, the CT scan visualizing the aneurysm sac more effectively and the angiography providing a vascular cartography. These two non-invasive exploratory examinations provide complementary data for the preoperative diagnosis and investigation of the aberrant right subclavian artery aneurysm.

[Epithelioid hemangioendothelioma of the liver and superior vena cava. Radiological results apropos of a case in an adult].

Epithelioid hemangioendothelioma is a rare, ubiquitous, vascular tumor, difficult to diagnosis but sometimes identified after detection of metastases, and with a prognosis intermediary between angioma and angiosarcoma. The tumors have been described as developing in the large venous trunks and recently lesions have been reported in liver. Little documented data exist with respect to radiologic appearances. A case is reported with a histologically confirmed hepatic localization in association with a lesion in superior vena cava.

[Spontaneous rupture of intracranial dermoid cyst. Clinical and radiological study].

A 22 year old woman had a seizure, and the skull X-ray showed an intracranial arched calcification. CT scan permitted diagnosis of dermoid cyst. Rupture of the cyst was testified by low density areas disseminated on the cortical surface and intra-ventricular fat level. Surgical removal confirmed dermoid cyst with rupture and fat fluid inside. Authors underline infrequency of such intra-ventricular fat level. CT scan, with low density of lipidic origin promote considerably such diagnosis both of the real nature of the cyst and of its rupture.

[X-ray computed tomography of extrahepatic cholestasis].

Findings in a series of 53 examinations performed in patients with extrahepatic cholestasis demonstrated the value of computed tomography exploration to determine mechanisms and etiology of biliary tract affections. Sensitivity of the CT scan for detection of biliary tract dilatations was equivalent to that obtained by ultrasound, and was even higher for certain types of patient (obese, distended, etc.). Results of this study combined with data in the literature enables precise diagnostic criteria to be established when determining etiology of these dilatations, which require investigation by a CT scan when ultrasound imaging proves unsatisfactory.

[Measurement of antetorsion of the femoral neck by ultrasonics. Comparison with x-ray computed tomography].

A method of measurement of femoral anteversion using ultrasounds is presented. It is easily reproducible and non-irradiating. It was tested in 100 hips and compared with measurement by tomodensitometry. The results were similar. Both methods were tested in dry bones and the results again were comparable. It is concluded that ultrasound measurements are reliable and without danger and should be used in preference.

[Hematoma of the psoas. Comparative diagnostic contributions of ultrasonography and x-ray computed tomography].

A 11 cases study of hematoma of the iliacus muscle underlines better results obtained by C.T. Scanner compared to those of ultrasonography examination in term of definite diagnoses. Comparison of density values and repeated examination were useful to assert diagnosis and to appreciate the course of the illness. Only C.T. Scanner was able to show which portion of the muscle was concerned. Authors correlated the C.T. Scanner results to the nature of the entrapment neuropathy clinically found: an isolated femoral nerve palsy or association with an obturator nerve dysfunction.

[X-ray computed tomography and primary thoracic seminoma].

The primitive thoracic seminoma is a rare tumor. Given their low frequency, these tumour have rarely been the object of C.T. exploration. It determines the compressive effect on neighbouring organs, the volume and extensive character of the tumor. C.T. exploration allows proper surveillance after therapeutic.

[Aneurysm of the abdominal aorta in infants. Apropos of a case].

The sudden development of an abdominal mass following umbilical artery catheterization during neonatal reanimation in a 1-month-old infant of an alcoholic mother was found to be due to an aneurysm of the abdominal aorta. Diagnosis was established by computed tomography and confirmed by arteriography. In the absence of any pathological examination, surgical treatment having been temporarily delayed, a mycotic origin for the aneurysm was suggested by the conditions of onset. A review of the 13 cases of primary mycotic aneurysms of the abdominal aorta in infants reported in the literature emphasizes the rare but serious nature of these lesions at this age.

[The value of tomodensitometric studies in the diagnosis of the herniated lumbar disk. Apropos of 155 operated disks].

Correlation of radiological and pathological findings in 155 cases of operated herniated discs emphasizes the value of a CT scan in the diagnosis of these lesions. Imaging by the scanner is a safe and relatively low-cost procedure and its reliability is identical to that of other conventional exploratory methods. It should, therefore, become the initial examination conducted during investigation of sciatica thought to be of discal origin. Reliability of results has varied between 85 and 90 p. 100, according to the author, for this essentially simple and atraumatic method. Confirmation of the presence of a hernia requires the observance of clear signs: material of discal density amputating the spinal canal and spreading over the dural sheath. False negatives or positives usually occur in borderline cases or in previously operated patients. Differences in clinical and computed tomography findings, with undoubted absence of signs on the scan image, require further investigation by radiculography.

[Tomodensitometry and pancreatic pathology].

Computed tomography is currently the most effective method for investigating the pancreas. Though far from superseding ultrasonography, which should always precede it, possible insufficiences of this examination can be corrected and doubtful images clarified. Its greatest usefulness is in acute pancreatitis, as the size of the lesion can be defined as well as subsequent therapeutic measures. It also appears to be the most reliable examination for chronic pancreatitis or cancer of the pancreas at the present time, but their differential diagnosis can raise problems when certain localized hypertrophic lesions exist. However, diagnosis of a pancreatic lesion is only possible when it deforms the gland or modifies its density, and it is illusory to expect early detection of lesions less than 2 or 3 cm in diameter, particularly in cancer cases.
