| Popis: | Cerebral arteriovenous malformations (CAVMs) are rarely diagnosed in utero. Most prenatal imaging of intracranial vascular malformations relates to Vein of Galen aneurysmal malformations (VGAMs) or Dural Arteriovenous Malformations (D-AVMs). We report a case of a fetal pial AVF with multiple fistulae and venous pouches, which appeared as an anechoic lesion on the prenatal ultrasound scan. The patient was asymptomatic with normal postnatal growth. No haemodynmaic disturbance was evident. Postnatal Computed tomography (CT), Magnetic Resonance Imaging (MRI) and catheter Digital Subtraction Angiography (DSA) confirmed the presence of a pial AVF. The angiographic findings and family history of nose bleeds suggests the diagnosis of Hereditary Hemorrhagic Telangiectasia. The largest AVF was embolized with tissue adhesive; the residual AVF subsequently removed by surgical excision. |
