Development Delay in a Child with Microcephaly and Birth Asphyxia: Explore Diagnosis beyond Hypotonic Cerebral Palsy

We describe a case of a 2-year-old female child who presented as emergency with acute gastroenteritis and severe dehydration. In this patient, there was a history of severe birth asphyxia, and the developmental milestones were delayed. The child was managed as hypotonic cerebral palsy elsewhere with antiepileptic drug and nutritional supplements. However, persistent abnormal pattern of breathing after adequate hydration and noncontributory metabolic profile raised the suspicion of alternate etiology. Later, the diagnosis of Joubert syndrome was established on contrast-enhanced magnetic resonance imaging of brain with findings of "molar tooth sign" appearance along with vermian hypoplasia. We present this case to alert the clinicians to explore all the differential diagnoses carefully whenever a child presents with the developmental delay associated with multisystem involvement.
