Spontaneous involution of optic pathway lesions in neurofibromatosis type 1: serial contrast MR evaluation.

PURPOSE: To evaluate with contrast MR the evolution in size, signal, and contrast enhancement of optic pathway lesions in four patients with neurofibromatosis type 1. METHODS: The four reported patients are children with ages ranging from 21 months to 13 years affected by neurofibromatosis type 1 and optic pathway lesions. No treatment of the optic pathway lesions was carried out in these patients. They have been followed by serial contrast MR. RESULTS: In all patients a change in size, signal, and enhancement of optic pathways lesions was noted with time, and in the last follow-up study a marked reduction in size and enhancement of optic pathway lesions was observed in all cases. CONCLUSIONS: Modification and regression of optic pathway lesions with spontaneous disappearance of the enhancement is demonstrated. This finding could have a crucial influence on the therapeutic approach of the optic pathway lesions.

Early diagnosis of optic glioma in children with neurofibromatosis type 1.

Twenty-five asymptomatic patients with neurofibromatosis type 1 (NF 1), aged 6-21 years, underwent the following examinations: intracranial magnetic resonance testing (MRI), visual acuity testing, ophthalmoscopy, and visual field and pattern reversal visual evoked potentials (VEPs). MRI showed enlargement of one or both optic nerves in six children, with bilateral involvement in three. VEPs were normal in all these patients; two of them had abnormalities on other visual examinations, although there were no subjective visual disturbances. These results show that VEPs cannot be considered as a screening test for optic pathway lesions in children with NF 1, as previously stated, and that other types of visual function examination may be more sensitive. These data may contribute to the establishment of more precise guidelines for the evaluation and treatment of children with NF 1.

[Reye's syndrome. Discussion of a clinical case].

A case of Reye's syndrome in an unweaned child aged 5 1/2 months is reported. The boy presented ingravescent neurological symptomatology accompanied by sporadic gastrointestinal signs and by marked renal impairment, with total, or nearly total absence of pathognomonic laboratory data. The diagnosis was confirmed by autopsy.

[Multiple hepatic abscesses: a pediatric case report].

The Authors describe the case of an immunologically healthy 14 year old boy presenting a hepatic infection with multiple abscesses. This case is of particular interest because of its rarity in Pediatrics. Probable etiologies, pathogenic mechanisms and treatments are discussed. The Authors underline the usefulness of ultrasonography as a diagnostic tool and as a non-invasive means of following the course of the disease.

[Screening of urologic pathology in newborns with prenatal and postnatal echography].

We compared the results, by prenatal ultrasonography, effected on 2592 foetus at the 15th-25th-35th weeks of gestation with the ones, made by postnatal ultrasonography, effected the 5th day of life on 2539 infants born from pregnancies previously monitored. We considered the obstructive and not obstructive malformations. The prenatal ultrasonography put in evidence 19 cases of urological pathology, which is 0.75%. The postnatal research established the truth of 14 cases, which is 0.55%; 7 cases underwent a precocious surgical operation. Percentage of positive false is 0.2%. The postnatal ultrasonography made evident 30 cases which can be considered pathological: 25 uropathy obstructive cases and 5 uropathy not-obstructive cases; 3 of them underwent precocious surgical operation. The result is 44 pathological cases (1.74% of infants). We also considered an heterogeneous group of non-nephro-urological anomalies (0.47%), a casual medical report of this research; in particular, 10 cases of surrenal hematoma and 1 case of neuroblastoma. The Authors remark that it's useful to complete the prenatal ultrasonographic research with another postnatal ultrasonographic research, particularly in the nephro-urological pathology; and they hope this system can be much more diffuse.
