Abstract: Trapped fourth ventricle (TFV) as a complication of post-hemorrhagic hydrocephalus (PHH) is widely reported in the pediatric population with a prior history of ventriculo-peritoneal (VP) shunt placement. Characterized by disproportionate dilatation of the fourth ventricle on serial neuro-imaging, it is rarely encountered in the early course of preterm infants and the differentiating clinical features are subtle and non-specific. Clinical alertness and sonographic correlation hold the key to early diagnosis. We report an early emergence of TFV in an extremely low gestational age newborn (ELGAN) following fulminant Pseudomonas aeruginosa meningitis, approach to management, and the neurological outcome. Fourth ventricle entrapment as a complication of perinatally acquired Pseudomonas aeruginosa meningitis in a surviving ELGAN is extremely rare.
