Symptomatic Subdural Hygroma Following Acinetobacter Meningitis in an Infant.

We present a case of a full-term newborn with prenatal congenital heart disease, admitted to a level III neonatal intensive care unit. After undergoing a surgical palliation procedure, he experienced a complicated recovery, including nosocomial sepsis with isolation of Acinetobacter nosocomialis in both blood and cerebrospinal fluid. Subsequently, he developed focal clonic seizures that were refractory to antiepileptic drugs, and imaging studies revealed the presence of a subdural hygroma. Surgical drainage was performed, resulting in the resolution of the seizures. This report highlights the rare occurrence of Acinetobacter meningitis unrelated to neurosurgery and its progression to subdural hygroma in an infant, emphasizing the importance of recognizing such complications as potential causes of refractory seizures following infectious processes.
