Unusual Presentation of a Hemiplegic Migraine in a Seven-Year-Old Child: A Case Report

In the pediatric population, headache is a common presenting symptom, and migraine is often the diagnosis. A hemiplegic migraine is characterized by an aura and sudden-onset weakness on one side of the body that usually resolves without causing any permanent neurological damage. In this case, we present a seven-year-old male child with a known case of proximal tubular dysfunction (homozygous mutation in the SLC4A4 gene) who presented to the emergency department with a one-day history of weakness on the right side of his body. A few hours after being discharged from the hospital, he began complaining of a severe headache on the left side, accompanied by photophobia, phonophobia, and high fever. Radiology scans and laboratory workup were unremarkable, and encephalitis was ruled out. He was later diagnosed with hemiplegic migraine based on his history and clinical presentation.
