Insights
Sotos syndrome, a genetic overgrowth disorder, may increase the risk of subdural hemorrhages (SDH) in infants. Consider Sotos syndrome in unexplained SDH cases, particularly with macrocephaly.
Area of Science:
- Genetics
- Neurology
- Pediatrics
Background:
- Subdural hemorrhages (SDH) in children carry high mortality and morbidity, often prompting investigation for abusive head trauma or underlying genetic disorders.
- Sotos syndrome, characterized by overgrowth, macrocephaly, and developmental delays, is rarely associated with neurovascular complications.
Observation:
- Two cases of Sotos syndrome are presented: one infant with SDH initially suspected as abuse, and another with enlarged extra-axial cerebrospinal fluid spaces.
- The enlarged spaces in the second case suggest a potential mechanism for SDH development in Sotos syndrome.
Findings:
- Individuals with Sotos syndrome may have an elevated risk of developing SDH during infancy.
- Macrocephaly and enlarged extra-axial spaces in Sotos syndrome could predispose to SDH.
Implications:
- Sotos syndrome should be considered in the differential diagnosis for unexplained pediatric SDH, especially when macrocephaly is present.
- Early diagnosis of Sotos syndrome can prevent unnecessary investigations for child abuse and guide appropriate management.
Abstract:
Subdural hemorrhages (SDHs) in the pediatric population are associated with a high mortality and morbidity and may present in the context of abusive head trauma. Diagnostic investigations for such cases often include evaluation for rare genetic and metabolic disorders that can have associated SDH. Sotos syndrome is an overgrowth syndrome associated with macrocephaly and increased subarachnoid spaces and rarely with neurovascular complications. Here, we report two cases of Sotos syndrome, one with SDH during infancy who underwent repeated evaluation for suspected child abuse prior to the Sotos syndrome diagnosis and the other with enlarged extra-axial cerebrospinal fluid spaces, demonstrating a possible mechanism for SDH development in this setting. These cases suggest that some individuals with Sotos syndrome may be at elevated risk of developing SDH in infancy and that Sotos syndrome should be on the differential diagnosis during a medical genetics evaluation in cases of unexplained SDH, especially in the setting of macrocephaly.
