Primary amebic meningoencephalitis in children: A case report and literature review.

This article presents the diagnostic and therapeutic journey of a 14-year-old male patient diagnosed with Primary Amebic Meningoencephalitis (PAM), incorporates a review of pertinent literature and a discussion on recent advancements in the study of this condition. The patient presented with symptoms of fever and headache for three days, accompanied by seizures and a half-day episode of altered consciousness. Upon admission, clinical findings included a mild coma, respiratory distress, rigidity of limbs, and negative pathological reflexes. The patient's history showed in a local outdoor pond swimming in July and August of the same year. Metagenomic Next-Generation Sequencing (mNGS) of the cerebrospinal fluid identified the presence of Naegleria fowleri. Cranial CT and MRI scans indicated signs of brain edema and meningitis. The patient was confirmed with pediatric primary amebic meningoencephalitis. A 45-day comprehensive treatment regimen was administered, encompassing anti-amebic medications, anticonvulsant therapy, management of brain edema, and intracranial pressure reduction. This case represents the longest survival period recorded for such pediatric cases in China. The purpose of this report is to heighten clinical awareness of PAM, share diagnostic and therapeutic insights, expand upon existing treatment approaches, and ultimately contribute to improving the survival rates of PAM patients.
