Diffuse cystic peritoneal lymphangiomatosis. Long-term clinical, ultrasonic and x-ray computed tomographic study. Apropos of a case

An adult male with episodic manifestations of abdominal lymphangiomatosis has been followed up over a 5 year period. This prolonged surveillance of clinical features combined with ultrasound and CT scan imaging has no doubt contributed to improved knowledge of diagnostic and physiopathologic factors of these rare lesions. The particular behavior of the case reported evokes discussion on the conventional surgical treatment of lymphangioma.     

Reversible cerebral lesions in eclampsia. Clinical and x-ray computed tomographic study

The appearance observed with CT during and following eclampsia seem to be related to edema, hemorrhagic lesions and ischemic lesions. The authors report on a reversible appearance of hypodense central grey nuclei and of the calcarine cortex fitting into this new context.     

Telethermography in the selection for x-ray computed tomographic study of herniated lumbar disks

Results of computed tomography and thermography examinations were compared in 80 patients with herniated disk lesions investigated by non-invasive radiological procedures. Thermography proved to be a very sensitive method but one of only relative specificity. The examination failed to contribute data in 10% of cases, and only one false-negative result was noted. Telethermography appears to be a reliable screening method enabling optimal selection of patients for scanning.     

Multiple duodenal lipomas. A x-ray computed tomographic diagnosis

In a 65-year-old man, upper endoscopy revealed several polypoid lesions into the duodenum, for which histologic examination of the biopsy specimens showed normal mucosa. CT studies demonstrated homogeneous fat density of these nodules, and thus were diagnostic of duodenal lipomas. The diagnosis was ultimately histologically confirmed by deeper peri-endoscopic biopsies. About this case and the some previously reported ones, the authors emphasize the interest of CT examination in this small bowel tumor.     

Optical assistance in guiding punctures under x-ray computed tomographic control

The authors describe a new technic for realisation of CT-guided punctures. This original device uses a buna tourniquet placed on the table for drawing on the skin the site of puncture and a movable light-visor for guiding the needle during the puncture. The advantages of this device are: no using of disposable or sterilised material; total freedom of the hand during the puncture; to be simple and quick.     

CT腹膜腔造影对腹膜转移瘤诊断的研究

目的 探讨ＣＴ腹膜腔造影（ｃｏｍｐｕｔｅｄ ｔｏｍｏｇｒａｐｈｙ ｐｅｒｉｔｏｎｅｏｇｒａｐｈｙ,ＣＴＰ）对腹膜转移瘤的诊断价值及临床意义。方法 回顾性研究有完整病史资料及手术病理结果,并经ＣＴ平扫及ＣＴＰ检查的腹膜转移瘤２５例,其中２０例ＣＴ平扫及ＣＴＰ发现与手术结果进行对照。结果 ＣＴ平扫及ＣＴＰ在所有腹膜受累部位对腹膜转移瘤的敏感性分别为４７．５％和７６．８％,尤其在双侧上间隙及结肠旁沟ＣＴ     

Hepatic Kaposi's sarcoma and AIDS. Ultrasonographic and x-ray computed tomographic aspects

AIDS-related Kaposi sarcoma is most often multicentric and extensive. Hepatic involvement is unusual and asymptomatic. An anicteric cholestasis may exist. Ultrasonography shows a pedicular echogenic infiltration and a heterogeneous parenchyma with small hyperechoic nodules. On CT, these hypodense lesions are related to the involvement of the hepatic pedicle. This is linked to angiosarcomatous tumorous tissue infiltration of the liver evolving along portal branches. In a patient suffering from cutaneous or digestive Kaposi sarcoma lesions, these radiological aspects are suggestive of hepatic involvement.     

Developmental x-ray computed tomographic and magnetic resonance studies of swinging frontal cerebral radionecrosis

Changes in CT scan and NMR imaging findings are reported in a patient with cerebral radiation lesions affecting first the left and then the right frontal cerebral cortex. This case is exceptional since voluntarily and by necessity the radiation dose for an inextirpable frontal sinus tumor had been very high. As a result of this radiotherapy, a survival of about 10 years was obtained under good conditions, with cerebral lesions provoking relatively moderate functional consequences.     

Comparison between ultrasonic and x-ray computed tomographic measurements of femoral antetorsion in children

The measurements of femoral torsion by ultrasounds have been performed in both hips of 10 patients according to the technique proposed by Zarate et al. The measurements with CT were done in the same patients according to a technique similar to that used by Hernandez et al. The correlation between US and CT is excellent as far as the minutest particulars of the technique are followed for US examination. The authors recommend ultrasounds, as a non irradiating, non aggressive procedure for the measurement of femoral torsion. US must replace both conventional X-ray and CT for femoral torsion assessment.     

Pericardial effusion with involvement of the superior aortic recessus of the pericardium. An x-ray computed tomographic case

Computed tomography imaging in a patient with a pericardial effusion showed fluid collection in the superior recessus of pericardium confirmed by mediastinoscopy. Topographic and morphologic criteria and anatomic bases of the radiologic diagnosis are described, and emphasis placed on the fact that because of density variations in pericardial effusions the latter has to be added to the already long list of abnormal opacities of Barety's space.     

Pancreatoblastoma. Ultrasonic and x-ray computed tomographic aspects. Apropos of a clinical case

A 4 year old child presented with a pancreatoblastoma, a tumor of the pancreas being an exceptional finding in children. Ultrasound and CT scan images of this pancreatic carcinoma are described as well as its course during chemotherapy. Diagnosis is difficult but can be assisted by guided fine needle puncture biopsy.     

3-dimensional reconstruction of x-ray computed tomographic views in fractures of the acetabulum

In 21 cases of acetabulum fractures of 19 patients, the authors compare the findings given by three dimensional reconstructions of axial CT scan cuts with the plain films. The number of CT scan cuts is reasonable for each patient. Working time is about 20 to 30 minutes for the technician. In the cases of complex and displaced fractures, three dimensional imaging brings often decisive informations for the therapeutic management of these patients. Unusual views are often allowed but completely adapted to each type of fracture.     

Jugular foramen: anatomic and computed tomographic study

The computed tomographic (CT) appearance of the jugular foramen was examined in detail, and anatomic and CT sections were correlated. The pars nervosa and pars vascularis were identified, and, with intravenous contrast enhancement, a rapid sequence of scans at a gantry angle of +30 degrees to the canthomeatal line demonstrated cranial nerves IX, X, and XI. The osseous margins of the jugular foramen were best shown by CT at planes of sections parallel and positive (0 degrees - 30 degrees) of the canthomeatal line. CT can be used to evaluate osseous anatomy and the jugular foramen with precision sufficient to confidently exclude an intracanalicular mass.
