Abstract
In the case presentation in the April 19, 1990, issue,1 Drs. Wolpow and Mark provided valuable insights into the diagnosis and treatment of brain abscess and pulmonary arteriovenous malformations, except that treatment of the latter with embolotherapy was not mentioned. On the basis of our experience with 100 patients with pulmonary arteriovenous malformations in the past 13 years, I would like to comment on several points in the discussion.
