[Inflammatory pseudotumors of the liver. Apropos of a pediatric case with radiological and ultrasonographic features and anatomopathological correlations].

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].

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.

[Acute pancreatitis disclosing an uncommon form of annular pancreas].

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.

[Tomographic study of the intra-abdominal digestive tract. Contributions of percutaneous echography and scanner in daily practice].

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.

[Hepatic steatosis in obesity in children].

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.

[Cholestatic viral hepatitis A with hepatic portal adenopathy].

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].

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.

[Purulent pleurisy caused by anaerobic bacteria. A retrospective study of 19 cases].

A retrospective clinical, biological, radiological and evolutive study of 19 cases of pleural empyema caused by anaerobic organisms diagnosed between 1980 and 1986 was carried out. These 19 cases accounted for 30.6 p. 100 of all cases of pleural empyema diagnosed during the same period. A local or general contributory factor was found in all patients; false passage, gastrointestinal pathology and buccal or dental diseases were the most frequent aetiological circumstances. The clinical picture was rather torpid, with a body temperature below 38 degrees C in 42 p. 100 of the cases, which delayed the diagnosis: the mean time interval between onset and diagnosis was 20 days. In nearly one half of the cases, blood stained expectoration was present and air-fluid levels were visualized at standard radiography and computerized tomography, which is the best exploratory method to evaluate the size and appearance of the pleural lesion, to guide percutaneous drainage and later to assess possible sequelae. The predominant anaerobic flora consisted of Gram-positive cocci and Bacteroides spp; in 70 p. 100 of the cases the anaerobic organism(s) was (were) sensitive to penicillin G. The course of the disease was favourable in all patients. Surgery was performed in 3 of the 19 patients on account of chest wall gangrene due to Clostridium perfringens in 1 case and of the presence of multiple fluid pockets making drainage ineffective in 2 cases.

Ultrasound of the traumatized spleen: left butterfly sign in lesions masked by echogenic blood clots.

Ultrasonic display of blood on both sides of the splenogastric ligament (left butterfly sign) in the left traumatized patient indicates hemoperitoneum within the lesser sac. Particular attention must be paid then to the splenic parenchyma, where isoechogenic blood clots can mask a hematoma. The association of subtile parenchymal changes and of a left butterfly sign are relevant of frank splenic lesions.

[Vesico-ureteral reflux. Ultrasonographic aspect of endoscopic treatment (excluding follow-up)].

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.
