The authors report the case of a 3-week-old girl with two enhancing extraaxial masses in the posterior fossa, one in the left cerebellopontine angle (CPA) and the other to the right of the vein of Galen. Serial magnetic resonance images obtained in this patient at 3 months and then at 2.5 years of age documented regression of the enhancing mass in the left CPA and development of a cerebellar brain arteriovenous malformation (AVM) in the same CPA location. Also documented were regression of the pineal region mass and formation of the major draining vein of the AVM. The findings in this case support the theory that cerebral AVMs have early postnatal growth potential.
