[Case of early hydrocephalus in mucopolysaccharidosis type 1]
Insights
Hydrocephalus is a rare complication of mucopolysaccharidosis I-H (Hurler Syndrome), particularly in infants. This case highlights an unusually early onset of hydrocephalus in a 5-month-old infant with Hurler Syndrome.
Area of Science:
- Genetics
- Pediatrics
- Neurology
Background:
- Mucopolysaccharidosis I-H (Hurler Syndrome) is a rare genetic metabolic disorder.
- Macrocephaly is a known feature in several metabolic disorders, including mucopolysaccharidoses.
- Hydrocephalus is an uncommon complication in Hurler Syndrome, typically observed in older children.
Observation:
- A 3-month-old infant was diagnosed with mucopolysaccharidosis I-H (Hurler Syndrome).
- The infant developed hydrocephalus at 5 months of age.
- This represents an unusually early onset of hydrocephalus in the context of Hurler Syndrome.
Findings:
- The hydrocephalus is likely communicating, stemming from storage material accumulation in the piaarachnoid.
- Impaired cerebrospinal fluid (CSF) absorption is the suspected cause of hydrocephalus.
- The early presentation challenges existing observations regarding the typical timeline of hydrocephalus in Hurler Syndrome.
Implications:
- This case underscores the variability in the clinical presentation of Hurler Syndrome.
- Early recognition of hydrocephalus is crucial for timely intervention in affected infants.
- Further research is needed to understand the mechanisms behind early-onset hydrocephalus in pediatric metabolic disorders.
Abstract:
One mucopolysaccharidosis I-H (Hurler's Syndrome) found in 3 months infant, was complicated with an hydrocephalus at the age of 5 months. If macrocephaly is known in several genetic inborn errors of metabolism, specially in the different mucopolysaccharidosis, hydrocephalus is quite more rare. It is probably communicating and due to accumulation of storage material in the piaarachnoid causing an impairment in CSF absorption. It occurs in the evolution of the disease and the reported cases concern only older children; our case is special by the early beginning of hydrocephalus.
