[Importance of computerized tomography in the early diagnosis of Bourneville's tuberous sclerosis].

CT findings in a series of 23 cases of tuberous sclerosis are presented. The great importance of CT screening for the early diagnosis of this disease and the opportunity of CT follow-up of subependymal nodules, for their high malignant potential are underlined.

[Diagnosis and treatment of craniosynostoses: the usefulness of CT combined with 3-dimensional reconstruction].

Craniosynostoses are craniocerebral and craniofacial dysmorphic states, characterized by early closure of one or more cranial sutures. In this pathology the perpendicular growth of the bone to the involved suture is disturbed (Virchow's theory). Craniosynostoses can be divided into: 1) single-suture synostoses (scaphocephaly, plagiocephaly, trigonocephaly), 2) multiple-suture synostoses (brachycephaly, oxycephaly) and 3) craniofacial dysostoses.

[Intracranial lipoma. Diagnostic contribution of computerized tomography].

Five cases of intracranial lipoma, diagnosed by computerized tomography (CT), are presented. CT findings of these rare and congenital malformations are described. CT is a useful and careful diagnostic procedure compared to other invading techniques, for the study of intracranial lipoma, and associated anomalies.

[The use of 3-dimensional CT reconstruction in childhood. Technics and dosimetry].

A new computer method has been developed that allows the reprocessing of standard CT scans to produce 3D surface images. We employed the 3D reconstruction program developed by Hitachi Medical System using an Ansaldo A-TOM XR 1200 scanner. The process requires only standard CT scanner hardware, and reconstruction time is comparable to that of sagittal and coronal reconstructions.

CT of anorectal malformation--a postoperative evaluation.

In spite of the progress in the field of surgical treatment of anorectal malformations, faecal incontinence is, in variable degrees, still an unpleasant and frequent postoperative sequela. Postoperative CT demonstrate the location of the pulled-through intestine, including whether it had been correctly placed through the levator ani and in the spincteric muscular complex. In our nine patients we discovered a correlation between the CT findings and the clinical picture.
