Insights
Hepatic hamartomas are common in children with tuberous sclerosis (TS), especially in older girls. This finding aids in diagnosing TS and offers crucial genetic counseling insights.
Area of Science:
- Pediatric Radiology
- Medical Genetics
Background:
- Hepatic hamartomas were historically considered rare in tuberous sclerosis.
- Accurate incidence data is essential for understanding disease manifestations.
Purpose of the Study:
- To determine the incidence of hepatic hamartomas in pediatric tuberous sclerosis patients.
- To review existing literature on this topic.
Main Methods:
- Ultrasonography was used to examine 51 children (25 boys, 26 girls) aged 3 months to 18 years.
- Literature review of reported cases.
Main Results:
- Hepatic hamartomas were identified in 12 (23.5%) of the children.
- Incidence was higher in girls (5:1 ratio) and increased with age, reaching 45% in those over 10.
- No symptoms of hepatic dysfunction were observed.
Conclusions:
- Hepatic hamartomas are a common finding in pediatric tuberous sclerosis.
- Their presence can aid in accurate diagnosis and genetic counseling for tuberous sclerosis.
Abstract:
Hepatic hamartomas were thought to be a rare finding in patients with tuberous sclerosis. The purpose of this study was to assess their incidence in children with tuberous sclerosis and to review the literature. During 1984-90 we examined 51 children by ultrasonography; there were 25 boys and 26 girls. Their age ranged from 3 months to 18 years. Liver hamartomas were seen in 12 (23.5%) of the children, more often in girls than boys (5:1). Their incidence increased with age reaching 45% in children over the age of 10. They did not produce any symptoms of hepatic dysfunction. Our study and review of reported cases prove that hepatic hamartomas are a common finding in patients with tuberous sclerosis and may be very helpful in providing a more accurate diagnosis and consequently help in genetic counselling.
