[Inflammatory pseudotumors of the liver. Apropos of a pediatric case with radiological and ultrasonographic features and anatomopathological correlations]. / Les pseudotumeurs inflammatoires du foie. A propos d'un cas pédiatrique avec aspects radiologiques et échographiques et corrélations anatomopathologiques.

Inflammatory pseudo-tumor of the liver (IPT) are benign encapsulated masses. IPT or inflammatory myofibroblastic tumor is a myofibroblastic proliferation with chronic inflammatory cell infiltration of unknown origin. A four-year-old girl, with cutaneous flushing of the face and biological inflammatory syndrome was referred for abdominal investigation. Ultrasound examination showed a 5-cm mass located in the anterior segment of the right hepatic lobe. After abdominal CT showing slightly vascular feature of this right hepatic mass, diagnosis was made through percutaneous US-guided fine needle biopsy. Surgical resection was performed and pathologic examination of the mass confirmed preoperative diagnosis. Clinical outcome was good.

[Chemical colitis caused by glutaraldehyde]. / Colite chimique au glutaraldéhyde.

Glutaraldehyde disinfectant solution may be a cause of toxic chemical colitis. We report two cases. Ultrasonic features were studied in one case and mimic colonic ischemia, inflammatory and/or infectious colitis. These findings were colonic wall thickening especially mucosal (hypoechogenicity) and submucosal (hyperechogenicity) layers. This diagnosis should be discussed when one sees a patient with echographic findings of acute left-sided colitis just after uncomplicated colonic endoscopy.

Exploracion por cortes del tubo digestivo intra-abdominal. Aportes de la ecografia percut nea y de la tomograf!a computada en la practica cotidiana / Exploration by samples from the digestive intra-abdominal tube

La exploracion del tubo digestivo ha sido y continua siendo competencia de la endoscopia completada por la radiologia convencional, pero el tubo digestivo se ha transformado en inevitable en emagendopia por cortes. La ecografia computada no reemplazan absolutamente a las exploraciones digestivas clasicas pero participan en el diagnostico de las afecciones digestivas en dos grandres circunstancias: por una parte, el balance de extension loco-regional de una afeccion ya conocida (caso de figura la mas simple), y, por otra parte, el descubrimiento fortuito de una formacion intraabdominal de origen digestivo en ocasion de la exploracion ya sea de una masa abdominal ya sea de un sindrome doloroso abdominal cronico o agudo, ya sea de una alteracion del estado general o de una anemia. En la practica cotidiana, el radiologo se enfrenta a veces a problemas de dificil interpretacion: una masa intraabdominal, es de origen digestivo?, un engrosamiento parietal digestivo, se debe a un artefacto por defecto de preparacion o una lesion organica perietal digestiva y, en este ultimo caso, es una lesion tumoral o inflamatoria?

[Tomographic study of the intra-abdominal digestive tract. Contributions of percutaneous echography and scanner in daily practice]. / Exploration par coupes du tube digestif intra-abdominal. Apports de l'échographie percutanée et du scanner en pratique quotidienne.

Endoscopy and radiological imaging are complementary. However the gastro-intestinal tract is routinely being imaged in CT and ultrasound, often performed for other indications. When an abnormality is discovered, several questions have to be addressed. Is the lesion due to a bowel abnormality? When bowel wall thickening is present, is it due to poor opacification or is it due to inflammation or tumor? Circumferential symmetrical thickening is more in favor of an inflammatory lesion, while focal asymmetrical thickening is more in favor of a neoplastic lesion. Inflammatory and lymphomatous lesion can have similar appearances. Guidelines to aid in diagnostic interpretation of gastrointestinal lesions are discussed, including features of appendicitis and obstruction.

[Acute pancreatitis disclosing an uncommon form of annular pancreas]. / Pancréatite aiguë révélant une forme particulière de pancréas annulaire.

We report a case of an acute pancreatitis revealing an annular pancreas associated with a pancreas divisum. Diagnosis was performed by endoscopic retrograde pancreatography with successful injection of major and minor papillae. Coexistence of pancreas divisum and annular pancreas is a rare congenital anomaly. Our case is original because the annular duct system encircling the duodenum is the ventral pancreas duct.

[Isolated intramural hematoma of the sigmoid. A rare complication of anticoagulant treatment]. / Hématome intra-mural isolé du sigmoïde. Une complication rare du traitement anticoagulant.

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.

[Hepatic steatosis in obesity in children]. / Stéatose hépatique par surcharge pondérale chez l'enfant.

The fatty liver infiltrations of the children are not uncommon and are often seen in particular diseases, mainly related to intoxication or metabolic diseases. The authors reported a case of heterogeneous fatty liver infiltration due to obesity with a good evolution after a hypocaloric diet.

[Acute pancreatitis and viral hepatitis A. Report of a case]. / Pancréatite aiguë et hépatite virale A. A propos d'un cas.

We are reporting the case of a patient with acute pancreatitis associated with viral A hepatitis with satisfactory recovery. To our knowledge, two similar cases have been reported.

[Splenic infarction in Plasmodium falciparum malarial attack]. / Infarctus splénique au cours d'un accès palustre a Plasmodium falciparum.

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.

[Cholestatic viral hepatitis A with hepatic portal adenopathy]. / Hépatite virale A cholestatique avec adénopathies pédiculaires hépatiques.

The authors report a case of type A viral hepatitis in an 8 year old boy in whom the clinical course was marked by prolonged cholestasis associated with porta hepatis lymphadenopathy. The positivity of anti-HVA IgM, the negativity of the other serodiagnostic tests, the parallel course of the hepatitis and the porta hepatis lymphadenopathy argus strongly in favour of the responsibility of hepatitis A in the development of this porta hepatis lymphadenopathy.

[Müllerian cyst. Apropos of a case of the prostatic region]. / Kyste müllérien. A propos d'un cas de la région prostatique.

One case of the unusual entity, prostatic müllerian duct cyst, is reported. Depending on their volume, they may, like in our case-report, or may not be symptomatic. Ultrasonography, C.T. scan and vasoseminal vesiculogram precised its midline location and its relationships with other adjacent anatomic structures. The endo-uretral approach to drainage was used successfully.

[Vesico-ureteral reflux. Ultrasonographic aspect of endoscopic treatment (excluding follow-up)]. / Reflux vésico-urétéral. Aspect échographique du traitement endoscopique (en dehors de la surveillance).

Thirty four children, mean age 6 years, with reflux of 56 ureters were treated by an endoscopic approach. The technique, a recent innovation, attempts to reinforce the intravesical trajectory of the ureter by the injection of a Teflon disk below the vesical mucosa at the ureteral meatus level. The Teflon disk used is radiotransparent but could always be detected by ultrasound imaging, whatever its size, as a very reflecting image with a posterior cone shadow.
