Q: What condition in this baby. This presentation since birth A: Diagnosis: Microcephaly Congenital The child displays the classic features of congenital microcephaly: Clinical Feature Observed in This Child ------ Disproportionately small head relative to face/body ✓ Prominent Sloping/receding forehead ✓ Visible Normal-sized or prominent-appearing face relative to small cranium ✓ Visible Relatively normal limb development ✓ Present Presentation since birth congenital ✓ As stated --- What is Microcephaly? Microcephaly is defined as a head circumference 2 standard deviations below the mean for age and sex severe microcephaly: 3 SD. It reflects reduced brain growth and impaired expansion of neural progenitor cells during development. --- Causes Congenital Microcephaly — Present at Birth Genetic: - Autosomal recessive primary microcephaly MCPH — mutations in genes like ASPM, CDK5RAP2, CENPJ - Chromosomal anomalies trisomy 13, 18, 21 - Genetic syndromes Angelman, Rett, Cornelia de Lange, Seckel syndrome Intrauterine Infections TORCH: - Congenital Zika virus prominent cause - Congenital CMV cytomegalovirus - Congenital rubella, toxoplasmosis, HSV Teratogenic/Environmental: - Fetal alcohol syndrome - Maternal phenylketonuria PKU - Radiation exposure in first trimester - Severe intrauterine growth restriction IUGR Metabolic: - Congenital disorders of glycosylation - Mitochondrial disorders --- Associated Features to Assess - Intellectual disability common, severity varies - Seizures / epilepsy - Spasticity or motor delay - Feeding difficulties - Hearing and vision problems - Dysmorphic facial features --- Workup Recommended 1. Head circumference — plot on growth chart OFC measurement 2. Brain MRI — cortical malformations, lissencephaly, pachygyria, calcifications suggests TORCH 3. Chromosomal karyotype / chromosomal microarray CMA 4. TORCH serology IgG/IgM for CMV, rubella, toxoplasma, HSV, Zika 5. Metabolic screening 6. EEG if seizures suspected 7. Ophthalmology and audiology referral 8. Neurodevelopmental assessment --- Management There is no cure for the underlying microcephaly, but management focuses on: - Early intervention — physiotherapy, occupational therapy, speech therapy - Seizure control — antiepileptic drugs as needed - Nutritional support - Multidisciplinary follow-up neurology, pediatrics, developmental medicine - Genetic counseling for the family --- Note: This is a clinical image interpretation for educational purposes. Definitive diagnosis requires full clinical evaluation, OFC measurement, neuroimaging, and investigations as above. Referral to a pediatric neurologist is strongly advised.
