Post-traumatic cysts detected by ultrasound in infant presented with first-time seizures: Case report.

In children at risk of neurological damage, such as those delivered prematurely or with history of birth asphyxia, cranial ultrasonography is frequently employed. Cranial ultrasonography also detects cysts, asymmetrical ventricles, periventricular white matter echogenicity, and hemorrhage, among other features. We report the case of an 8-month-old boy who was brought to the emergency department with a history of head trauma followed by seizures. Bedside cranial ultrasonography revealed multiple bilateral intracranial cysts, consistent with porencephalic cysts. Brain magnetic resonance imaging is the gold standard for identifying porencephaly and distinguishing it from other cysts. However, because of time restrictions in emergencies, cranial ultrasonography for a quick assessment in neonates and infants can be appropriate, as was the case in our encounter.
