Fatty infiltration of the pancreas in Shwachman's syndrome: computed tomography demonstration.

The authors report the case of three siblings with Shwachman's syndrome in whom computed tomography (C.T.) gave the diagnosis of fatty infiltration of the pancrease, by virtue of its specificity in identifying fat. The clinical and radiological features of Shwachman's syndrome as well as the differential diagnosis of fatty infiltration of the pancreas in childhood are reviewed.

Percutaneous vascular foreign body retrieval: experience of an 11-year period.

Over an 11-year period, percutaneous retrieval of intravascular foreign bodies was performed in 12 patients, using urological forceps and retrieval baskets. No clinically significant complication occurred, success rate was 100%. Review of 176 cases from the literature showed a success rate of 90%.

Local urokinase infusion for total occlusion of the lower abdominal aorta. Report of two cases and a review of the literature.

Two patients with acute occlusion of the lower abdominal aorta have been successfully treated with total of 7,425,000 and 8,850,000 units of urokinase infused locally over 93 and 86 hours, respectively, with restoration of flow. No complication occurred.

Computed tomographic arteriography (CTA) of the liver. Evaluation of technique, results and indications.

Computerized tomographic liver angiography was performed in 57 patients, of which 47 had metastatic disease. The goals of the investigation were to preoperatively 1. determine number, extent and nature of liver lesions, 2. define the hepatic vasculature. Early CTA could in 14 of the patients correctly direct further clinical management. CTA is a good examination modality for selecting candidates for liver surgery for neoplastic disease.

Tension mediastinal emphysema: emergency percutaneous drainage with CT guidance.

Four patients aged 8 to 54 years, under mechanical ventilation, presented with sudden tension mediastinal emphysema and exhibited typical clinical symptoms of compromised venous return. Diagnosis of tension mediastinal emphysema was confirmed by CT. A percutaneous catheter with a diameter varying from F12 to F20 was inserted in the anterior mediastinal compartment with CT control and connected to a waterseal aspiration. Emergency treatment was efficient in all patients. Percutaneous aspiration was continued for 3 to 20 days.

Adenolipoma of the liver. A unique case with ultrasound and CT patterns.

Lipomas rarely occur in the liver. However, because of the widespread use of ultrasound and CT in the diagnosis of liver disease, one should be familiar with their appearance, as confirmed diagnosis may spare the patient major investigations. The value of CT is emphasized in association with percutaneous biopsy when the appearance of the tumour is not classical. Ultrasound patterns are discussed.

Computed tomography with geometrical enlargement.

Third generation CT scanners perform examinations of small objects without employing all the detectors. Geometrical enlargement solves this problem by moving the tube-detector assembly according to the size of the object to be scanned; this improves spatial resolution, reducing both the tube current and the skin dose. Such an application for pediatric CT and small objects is of particular interest.

[Computed tomography guided percutaneous aspiration and drainage of thoracic and abdominal fluid collections (author's transl)]. / Aspiration et drainage percutanés des collections thoraciques et abdominales sous contrôle tomodensitométrique.

Computed tomography can be of value in guiding percutaneous aspiration and drainage of thoracic and abdominal fluid collections of various origins and localizations. Puncture-aspiration is of diagnostic importance when computed tomography findings are non-pathognomonic. Techniques employed for percutaneous drainage of infected fluid are described. Puncture-aspirations and percutaneous drainage of infected fluid are described. Puncture-aspirations and percutaneous drainage under computed tomography guidance are free from major complications, and represent a more valid therapeutic method than surgery, being simpler to perform and supplying identical results.

[Frontal and sagittal sections in whole body x-ray computed tomography]. / Les coupes frontales et sagittales en tomodensitométrie corps entier.

In sufficiently supple individuals, longitudinal sections are interesting in the case of extensive lesions because they provide a global view, whereas transverse axial sections give only a segmentary view of the pathological processus. They are of value in the study of lesions of the thorax, abdomen or pelvis. However, because of their anatomical and technical restrictions, they should be reserved for certain special cases.

[X-ray computed tomography in the study of anterior instability of the shoulder. Study of a series of 23 cases]. / Apport de la scanographie dans l'étude de l'instabilité antérieure de l'épaule. Etude d'une série de 23 cas.

The place of standard CT scan imaging more particularly when combined with double contrast arthrography, is defined in the preoperative screening of patients with anterior instability of the shoulder. The joint scan provides complete data on the anatomic elements of the shoulder lesion, particularly with reference to the glenoidal labrum and the anterior capsular structure. It is also of major diagnostic value in painful subluxations.

Radiological diagnosis and therapy of pulmonary arteriovenous fistulae in a patient with an atypical clinical history: a case report.

Pulmonary arteriovenous fistulae were first managed nonsurgically by Porstmann in 1977 with homemade metallic coils (1). During the intervening twenty years better catheterization techniques have been developed and our understanding of the clinical outcomings of these lesions has improved. This report discusses the natural history of pulmonary arteriovenous fistulae, including the neurological and other complications, the importance of family screening in the detection of asymptomatic family members, the diagnostic strategy and the description of improved techniques for embolotherapy with stainless steel coils.

Small intestinal obstruction caused by extramedullary hemopoiesis and revealing myeloproliferative syndrome.

A 60-year-old woman was admitted with mild intestinal obstruction. Enteroclysis showed segmental narrowing with mucosal fold thickening of the proximal jejunum. Computed tomography in addition demonstrated enlarged mesenteric lymph nodes in the proximity of the diseased intestinal loop. Histological examination of the resected intestinal segment showed extramedullary hemopoiesis. Bone marrow examination confirmed myeloproliferative syndrome.

[Diagnosis and percutaneous treatment of pulmonary hydatid cyst. State of the problem apropos of a case]. / Diagnostic et traitement percutanés du kyste hydatique pulmonaire. Etat de la question à propos d'un cas.

A pulmonary hydatid cyst was diagnosed and cured by percutaneous CT guided aspiration. Pleural effusion related to incomplete aspiration of the loculated cyst was observed. No deleterious effect occurred, after a follow-up of 22 months.
