Lenticulostriate Vasculopathy

  • Etiology: Usually a normal variant
  • Imaging US:
    — Unilateral or bilateral
    — Branching, linear or punctate echogenicity in basal ganglia
  • DDX: TORCH infection, intrauterine ischemia, cocaine exposure, Trisomies 13 and 21, twin-twin transfusion, neonatal lupus, neonatal hypoglycemia
  • Complications:
  • Treatment:
  • Clinical: Nonspecific association with TORCH infections and chromosomal abnormalities and malformations and hypoxic ischemic states
