Pseudocysts of the pancreas in children: which cases require surgery?

The need for surgery in pancreatic pseudocysts in children is directly related to the status of the duct of Wirsung. Clinical deterioration was often the factor leading to surgery. The retrospective study of ten cases of pancreatic pseudocyst pointed to the value of ultrasound as an indicator of pancreatic duct involvement. CT was also of help in one case. ERCP, performed only in one patient before surgery, may be indicated in difficult cases.

Pulmonary vascular nodules: new sign of left lower lobe collapse in children.

Left lower lobe collapse can be suspected in children on a frontal chest film when three or more peripheral left upper lobe vessels are seen end-on along the left heart border. The peripheral vascular changes are mainly due to the backward and downward displacement of the hilus. This "vascular nodule sign" was evident in 25 (70%) of 36 cases of left lower lobe collapse. Its frequency in normals is less than 10% and may be accounted for by lordotic projection. Although not entirely specific, this sign, easily noticeable even on an underexposed film, should raise the possibility of left lower lobe collapse.

The changing aspects of cholelithiasis in children through a sonographic study.

Ultrasonography has made the study of the biliary tract easier. This may account for an apparent increase in the incidence of cholelithiasis in children. Twenty-nine cases of biliary stones, mostly gallstones, were seen in a 3 year period. More than half of the cases were secondary to a definite cause, among which the interruption of the enterohepatic circulation of bile salts should be emphasized. The etiological factors of biliary stones and biliary sludge appeared identical in our material.

[Congenital pulmonary lymphangiectasis. One new case with complete blockage of the return venous pulmonary circulation and marked interstitial emphysema].

In this unusual case of bilateral congenital pulmonary lymphangiectasia with complete block of pulmonary venous return, the radiological diagnosis was made difficult by the association of the lymphangiectasia with bilateral interstitial emphysema. Routine dissection of the heart, considered to be normal since the cardio-thoracic index was only 0.45, relealed the true cause of death. The heart was the site of extreme hypoplasia of the left heart with complete mitral and aortic atresia. The ostium secundum being completely closed, the left atrium, after receiving the pulmonary veins, was completely blocked. It communicated neither with the right atrium, nor with the non-existent left ventricule.
