Macrocephaly and subdural collections

Area of Science:

• Pediatric Radiology
• Neuroradiology
• Child Abuse and Neglect

Background:

• Enlarged subarachnoid spaces are common in infants with macrocephaly.
• Benign enlargement of the subarachnoid spaces is a frequent diagnosis in this population.
• Subdural collections can infrequently complicate enlarged subarachnoid spaces.

Purpose of the Study:

• To differentiate benign enlarged subarachnoid spaces from abusive head trauma in infants.
• To investigate the relationship between enlarged subarachnoid spaces and subdural collections.
• To clarify diagnostic challenges in pediatric macrocephaly evaluations.

Main Methods:

• Review of pediatric neuroimaging studies for macrocephaly.
• Analysis of cases with enlarged subarachnoid spaces and subdural collections.
• Correlation of imaging findings with clinical presentations and outcomes.

Main Results:

• Benign enlarged subarachnoid spaces are a common finding in infants presenting with macrocephaly.
• Rare instances of subdural collections were observed in association with enlarged subarachnoid spaces.
• These subdural collections can mimic signs of abusive head trauma.

Conclusions:

• Enlarged subarachnoid spaces in infants require careful evaluation to exclude complications.
• Distinguishing benign enlarged subarachnoid spaces from abusive head trauma is crucial.
• Subdural collections associated with enlarged subarachnoid spaces can present diagnostic challenges.
