[Ultrasonography and x-ray computed tomography in the diagnosis of intra-abdominal textiloma. Apropos of 12 cases].
Feared by every surgeon, retained surgical sponges (or gossypiboma) are rare iatrogenic entities. Ultrasonography and computed tomography are very valuable, providing an immediate answer in the majority of cases. We report 12 cases of intra-abdominal retained surgical swabs. The ultrasonic pattern was made whether of a large poorly echogenic mass with a hyper-echogenic center and sharply delineated posterior acoustic shadow (7 cases) or of a large acoustic shadow posterior to a solitary highly echogenic area (4 cases). Computed tomography demonstrated whether large peripherally enhanced cystic mass associated with serpiginous or spongiform central area (5 cases) or heterogeneous abscess-like fluid mass.

Acute fatty liver of pregnancy: CT evaluation. Case report.
CT scans of two patients with acute fatty liver of pregnancy were reviewed in conjunction with the clinical evolution of this uncommon and potentially fatal disorder. In each of the CT scans, liver density measurements were less than those of the spleen. While the findings are non-specific, in the proper clinical context they are highly suggestive and may be the sole method of diagnosis, as these patients often have coagulation problems which rule out liver biopsy. It is an important diagnosis, as the high maternal and fetal mortality rates appear to be considerably reduced by early foetal delivery.

Outpatient peripheral angioplasty: survey of complications and patients' perceptions.
We report our experience with a total of 79 peripheral angioplasties performed in 64 patients on an outpatient basis between July 1983 and April 1985. Review of the medical files and a telephone inquiry in 58 subjects (72 angioplasties) revealed no major complications, a low rate of minor complications (1.5%), and a high degree of patient satisfaction (99%).

[Acute fatty liver of pregnancy. Apropos of 4 cases: contribution of x-ray computed tomography].
Acute fatty liver of pregnancy is a disease of the third trimester, generally considered to be rare and to have a grave prognosis. Histologically the characteristic fine droplet steatosis usually produces distinct vacuolization. Successful treatment depends on accurate diagnosis and early delivery. Computed tomography is of value in the diagnosis of fatty liver through liver and spleen attenuation value measurements. We reviewed 4 cases of acute fatty liver of pregnancy. Computed tomography was performed in two cases and was very helpful in the diagnosis of this condition.

[The urorectal syndrome caused by abdomen-levator incoordination in children].
We have studied thirty four children (mean age 6.6 years) with severe functional constipation, associated or not with encopresis. In twenty three cases the defecography showed a persistent anorectal angle due to failure of puborectalis sling relaxation during defecation straining. Voiding disorders, unknown to parents, but demonstrated by obstructive uroflowmetry, are also seen in nineteen of these children. Therefore is definite a true urorectal outlet obstruction syndrome by spastic pelvic floor mechanism. The exact etiologic factor of these functional abnormalities remains undefined. All children were managed by biofeedback training. A satisfactory result (with six months follow up), has obtained in fourteen cases.

Ultrasound and CT of peritoneal recesses and ligaments: a pictorial essay.
US and CT permit one to visualize peritoneal recesses and ligaments. Ultrasonic analysis relies mostly on the liquid contrast of peritoneal effusions. CT demonstrates more readily the fatty and vascular contents of ligaments. Thus ultrasound displays essentially the thin part of ligaments, which CT is unable to show due to kinetic blur, whereas CT demonstrates readily the thick fatty parts of those peritoneal elements.

[Ultrasonics in abdominal emergencies. Results of a series of 179 cases].
The study of a series of 179 emergency ultrasonic examinations showed a sensitivity of 97% and a specificity of 98%. Such results confirm the reliability of real-time sonography in the assessment of the acute abdomen, obstructive intestinal syndromes still requiring mainly conventional procedures. With this exception, the part of ultrasound in the diagnostic and the therapeutic strategies is essential. Associated to plain X-ray films, it enables one to curb down the number of other imaging procedures, such as IVP, angiography, or CT. Emergency ultrasound, particularly in traumatology, requires trained, competent radiologists. Performant machines should be available in admittance and intensive care wards.

[Radiographic aspect of enterocystoplasties using the Kock technic].
Normal radiologic images obtained during postoperative review examinations of patients with bladder epithelioma, treated by cystectomy and continent enterocystoplasty using the recently introduced Kock's technique, are described and a programme of radiologic follow up of these patients proposed.

[Yellow nail syndrome. Apropos of a case. A review of the main radiologic manifestations].
The authors report a case of "yellow nail syndrome" and emphasize the radiological features of this recently described entity which physiopathology has not yet been established. A new feature to be described: a non symptomatic pericardial effusion in association with long standing bilateral pleural effusions.

Ossification of the posterior longitudinal ligament after cervical irradiation.
A case of ossification of the posterior longitudinal ligament (PLL) at the cervical level one year after cervical irradiation is reported. This condition is rare in Caucasian people. The cause is unknown. The particular circumstances of ossification occurrence in the case reported allow us to propose a new etiological hypothesis.

[Isolated intramural hematoma of the sigmoid. A rare complication of anticoagulant treatment].
The authors report a case of intra-mural hematoma of the sigmoid associated with anticoagulant therapy. The small intestine is the site of predilection for intra-mural hematoma and the colonic site is very unusual. Our case was revealed by an obstructive syndrome. The diagnosis, suggested by the increased prothrombin time, was confirmed by ultrasonography and endoscopy. The treatment was symptomatic with nasogastric suction and correction of any hemostatic disorders.

[Splenic infarction in Plasmodium falciparum malarial attack].
Splenic infarct during P. falciparum malaria is rare but well known. We report one case where ultrasonography and computed tomography suggested the diagnostic, showing respectively in splenic parenchyma a peripheral hypoechoic lesion and a low attenuation lesion. Diagnostic was confirmed by spontaneous regression during following days. We shall encounter more frequently than nowadays this rare entity due to expanding tourism and P. falciparum resistance.

[Vascular radiology without hospitalization. Apropos of 306 angiographies and/or peripheral percutaneous transluminal angioplasties done on an ambulatory basis].
A study on the safety of outpatient angiography and interventional radiology was undertaken. The authors reviewed the medical files of 286 patients and conducted a late telephone inquiry in 249 patients (87%) who underwent these procedures on an outpatient basis : arteriographies (221) or percutaneous transluminal angioplasties (76) and a few intravenous studies (9). The results revealed a high degree of satisfaction from the patients (98%), no major complications and a very low incidence of minor complications (3%).

[X-ray computed tomography in purulent pleurisy].
Complementary CT scan imaging during investigation of 18 cases of empyema showed it to be an essential examination, since it established the diagnosis in all cases, determined possible extension of the infectious process and possible causal lesion, defined the most effective approach for percutaneous drainage and evaluated efficacy of the later.
