Endovascular treatment of spinal arteriovenous fistula in a young child with hereditary hemorrhagic telangiectasia. Case report.

Hereditary hemorrhagic telangiectasia ([HHT] or Osler-Weber-Rendu syndrome) can manifest as sudden onset of epistaxis or neurological deficit in a child with characteristic mucocutaneous telangiectasias or as an asymptomatic bruit with or without overlying cutaneous vascular lesions. The authors present a case study of a pediatric patient with HHT in whom a screening computerized tomography (CT) scan of the chest revealed an asymptomatic arteriovenous malformation (AVM) of the spine. An 18-month-old child with a strong family history of HHT, including fatal central nervous system (CNS) hemorrhage and pulmonary AVMs, presented with a cutaneous telangiectasia of the pinna.
