    Notes: Abstract We report a patient in whom a prenatal diagnosis of an intrapulmonary cyst was made by ultrasonography. To our knowledge, no such case has been reported before and prenatal diagnosis permitted prompt management of an asymptomatic neonate.

    Notes: Summary Based on a report of 16 patients, the authors describe and evaluate the sonographic aspects of renal inflammatory diseases (RID) in children. In acute disease, thickening of the renal pelvic wall as evidence of pyelitis was the most common pattern demonstrated. Increased renal volume, nontumoral parenchymal area of hyperechnogenicity, abscess-type mass or calcified solid mass (in the case of xanthogranulomatous pyelonephritis) were other aspects encountered. Related findings included evidence of chronic pyelonephritis (cortical thinning) and of renal malformations. In patients with RID, the role of ultrasound is doubly important. While it is being employed increasingly as a screening test, it is most useful as a follow-up technique to detect complications and assess renal growth. Nevertheless, it should be stressed that ultrasound may be totally normal in cases of RID and complementary examinations (IVP, VCUG and nuclear scanning) are still necessary.

    Notes: Summary This report describes the last 16 cases of congenital primary obstructive megaureter (CPOM) encountered at our institution, whereby antenatal diagnosis was an important method of detection (13 of 16 cases). In most cases, no precise diagnosis was established in utero (2 of 13 infants). This lack of accuracy is of little importance, since all babies with suspected uropathies undergo a uroradiological work-up after birth (ultrasound, voiding cystogram, and urogram). Our series showed a marked male predominance (80%). CPOM showed a high potential for spontaneous resolution after birth (40%). Therapeutic decisions should be based mainly on studies of renal function (quantitative isotopic nephrogram with diuretics). Therefore, as long as renal function has not deteriorated during follow-up, conservative management should be elected first. Only cases showing clinical symptoms or decreased renal function should be treated surgically.

    Notes: Abstract We report a rare case of transitional cell papillary carcinoma of the bladder in a 10-year-old girl who had hematuria. The tumor was diagnosed and assessed through VCUG and ultrasound. The tumor protruded into the urethra during micturition and its mobility was observed by both diagnostic procedures.

    Notes: Abstract A group of 10 pediatric patients had renal hyperechogenicity and reduced renal mass. The authors wish to suggest a relationship between renal hyperechogenicity and glomerular hyperfiltration according to Brenner's theory on the progressive nature of kidney disease. Reduced renal mass was related to multicystic dysplastic kidney (3 cases) nephrectomy (3 cases) and to reflux nephropathy (4 cases). The hyperechogenicity was diffuse in 6 cases with the preservation of cortico-medullary differentiation and was localized in all four cases of reflux nephropathy producing a “pseudotumoral” appearance. Hyperfiltration was confirmed by isotope studies in all 3 cases where it was performed. This condition together with secondary glomerulosclerosis could explain hyperechogenicity. The predicitive value of such patterns are still unclear; yet such findings should lead to appropriate radiolocal, functional, clinical and dietary measures.

    Notes: Abstract The authors report their experience with the perinatal diagnosis of six cases of hepatic cyst and six of liver hyperchogenicities. The in utero diagnosis of hepatic cysts was difficult when the cysts were large or subhepatic. A precise diagnosis was sometimes achieved only after surgery. Small intraparenchymal cysts tended to regress spontaneously. Liver hyperechogenicities were diffuse or localized. They were unrelated to liver infection, tumors, meconium peritonitis or biliary tract anomaly. Both entities could be related to vascular disruption phenomenon (VDP) in which structural anomalies result from damage to normal development of embryonic or fetal vessels with anomalies of perfusion to the developing organs. The consequences of VDP to the liver are variable depending on the time and duration of the phenomenon. Localized infarct or ischemia can fibrose or calcify leading to segmental hyperechogenicities. Necrosis with tissue reabsorption can be the origin of some (sub)hepatic cysts. When such anomalies are detected there should be a careful study of the placentation, and a search for potential associated anomalies should be undertaken.

    Notes: Abstract A case of an in-utero torsion ovarian cyst is reported. The diagnosis was made antenatally and the 4-cm cystic mass was followed by US from birth until the age of 3 months. Surgery was delayed until the baby reached a satisfactory weight. In the mean-while, the follow-up studies showed the mass to wander in the abdomen. Surgery revealed an ovarian cyst. Ovarian torsion cysts should be considered in the differential diagnosis of wandering tumors.

    Notes: Abstract Sonographic examination of the adrenal glands of three newborns with congenital adrenal hyperplasia demonstrated a cerebriform pattern. This is introduced as a sonographic feature specific to the disease. This finding in patients with ambiguous genitalia should suggest the diagnosis even if the adrenals are not significantly enlarged, and should prompt appropriate biochemical analysis and treatment.

    Notes: Abstract In the neonate, hyperechoic thickening of the ependyma is believed to be related to ventriculitis. Yet, in our experience, this sign is much more often observed in association with subacute intraventricular hemorrhage (IVH), without infection. Sixty premature neonates were prospectively studied. The observations of transfontanellar sonograms (intracranial hemorrhage, ependymal echogenicity, and ventriculomegaly) were correlated with the results of MRI, lumbar punctures and clinical work-up. Intracranial hemorrhage was detected in 28 patients, and hyperechoic thickening of the ependyma was observed in 21 of them, all of whom had IVH. In 9 of these 21 patients IVH was diagnosed retrospectively thanks to the visualization of the hyperechoic ependyma. In all but one, this sign persisted for at least 2 months after disappearance of other signs of IVH. MRI demonstrated the presence of hemosiderin and ferritin in ependymal or subependymal location only in patients with hyperechoic ependyma. One of our patients had in utero diagnosis of IVH owing to the visualization of the same hyperechoic aspect of the ependyma. Nine of the neonates with hyperechoic ependyma developed ventriculomegaly, and three underwent surgery. Hyperechoic thickening of the ependyma in prematures often results from a subacute IVH. It is related to hemoglobin catabolites which can be detected by MRI. It does not require immediate potentially harmful diagnostic punctures. The presence of this hyperechoic rim allows a retrospective diagnosis of IVH and indicates a clinical and sonographic follow-up in newborns at risk for secondary hydrocephalus.

    Notes: Abstract Thanks to the wider use of sonography to examine the spinal content in the neonate, normal anatomy and anomalies may be detected easily. Yet, unusual sonographic patterns are also observed. These must be differentiated from true pathologies. During a prospective study of 103 neurologically asymptomatic neonates, atypical sonographic patterns were found in 16 patients, corresponding to normal variants in 13. Nine of these 13 patients presented with a widening of the distal part of the central echo complex (one had a dilated ventriculus terminalis). Nerve roots of the cauda equina were disposed asymmetrically in three patients; the spinal cord movements were still present. In two of these babies, this distribution was associated with thin arachnoid pseudocysts. One patient presented with transitorily hyperechoic and narrow subdural spaces, probably related to neonatal dehydration. None of the 13 patients showing normal variants required any treatment. The other 3 patients (of 16) presented with equivocal entities of unknown evolution: sonographic tethered cord, fibrolipoma of the filum terminale and epidural varices. Sonography is highly accurate in evaluating the spinal cord content and aids differentiation of normal and normal variants from equivocal or pathological entities.
