Near-Fatal Acute Giant Intracranial Aneurysm Rerupture In 7-Month-Old Infant

Background Aneurysm rerupture and bilateral fixed and dilated pupils (bFDPs) typically have a poor prognosis across all age groups. The synchronous occurrence of both features in the infantile demographic has not been previously reported. Case Description We describe the near-fatal clinical course of a 7-month-old infant who experienced an acute giant aneurysm rerupture with signs of bFDPs. The patient was rapidly managed with neurosurgical intervention and has achieved a favorable outcome 1 year later. Conclusions This case highlights that survival of infants who present with intracranial aneurysmal rerupture and bFDPs is amenable to rapid neurosurgical intervention and should be remembered in clinical practice.
