A 16-month-old boy presented to his pediatrician following a 3-week history of left head tilt and a 3-day history of cessation of crawling. Developmental history was significant for delays in sitting independently (8 months) and crawling (12 months), necessitating physical therapy for delayed gross motor milestones. Birth history and all other past medical history were unremarkable. Neurologic examination was positive for a mild left head tilt and lower extremity proximal muscle weakness on ventral suspension.
Muscle bulk, tone, sensation, reflexes, and coordination were all within normal limits. His MRI of the spine was ordered ( images attached). What could be the diagnosis for this patient? *This case is from Docplexus Editorial team for educative purpose only
