ABSTRACT
Nephroblastomatosis is an abnormality of nephrogenesis and has been defined as the persistence of metanephric blastema into infancy. The association of these foci of fetal tissue with Wilms' tumor has been repeatedly documented in the literature. Numerous imaging modalities currently enable the detection of nephroblastomatosis and follow-up of patients to detect neoplastic change, which is especially indicated during infancy and early childhood, when the likelihood of Wilms' tumor developing is highest.

La nefroblastomatosis es una alteración de la nefrogénesis que se define como la persistencia de blastema metanéfrico en la infancia. La asociación de estos focos de tejido fetal con el tumor de Wilms se encuentra ampliamente documentada en la literatura. En la actualidad disponemos de numerosas técnicas de imagen que van a permitir el diagnóstico y seguimiento de esta entidad, especialmente en los primeros años de vida, cuando el riesgo de malignización es mayor (AU)

We present 6 months' clinical experience in the use of computerized radiography system in a Pediatric Radiology Service. The basic technology of the system and its utilization are described. An analysis is made of its principal advantages, like the reduction of the repetition of films, increased quality and diagnostic information, and reduction of the dose of radiation, and the practical disadvantages of the system are commented.

Pulmonary sequestration is a congenital anomaly in which an aberrant systemic artery arising from the thoracic or abdominal aorta supplies part of the lung, usually the lower lobes. The sequestrates part of the lung may be anatomically included in the substance of the lobe (intralobar) or may be separate from the other lobes, being contained within its own pleural investment (extralobar). The cases of ten patients with sequestration of the lung seen during a seven-year period are reviewed, with special consideration of their clinical and radiographic findings. Emphasis is made on the differences of our cases with those of the literature: 1) Eighty per cent of the patients had previous symptoms; 2) The intra/extralobar ratio was 1.5/1; 3) All intralobar sequestrations were indifferently localized in left or right lower lobes, and 4) Associated anomalies were present with the same incidence in the two classic forms.

A case of intestinal intussusception (I.I.) is described in a newborn and 42 cases in the literature revised. I.I. is not a frequent entity in the neonate and has special clinical and radiological characteristics. Symptomatology of patients is unspecific and makes diagnosis difficult. The elevated incidence of necrosis and intestinal perforation, possibly related with the delay with which diagnosis is effected, is without doubt the determing factor in the high incidence of mortality in these patients. The finding of a conditioning organic lesion is much more frequent in the neonatal period than later ages.

Four cases of congenital cystic adenomatoid malformation are presented. The age of the patients ranged from 1 day to 7 years. All cases were treated surgically and 3 of them survived. The only death in the group corresponded to the neonatal case. The clinical, radiological and patological features of congenital cystic adenomatoid malformation are also reviewed. Occasionally the clinical manifestations will be hardly noticeable or non existent and the malformation may be diagnosed beyond the neonatal period in the course of a radiological examination performed as routine or because of repeated respiratory infections. Surgery is the treatment of choice. In the group of neonates where the cystic adenomatoid malformation doesn't cause respiratory difficulty the authors feel that it might be advisable to postpone surgery until a later date.
