Galenic arteriovenous malformation with precocious puberty.
Pineal lesions may appear with precocious puberty. In this report, a patient with precocious puberty and macrogenitosomia caused by an arteriovenous malformation in the pineal region is presented. This vascular malformation was not visualized during investigations 3 years before the present series. It appears that the vascular malformation increased considerably in size within a 3-year period. This case suggests that some arteriovenous malformations may take a malignant course, increasing rapidly in size and behaving like tumors by causing destruction and compression of surrounding structures. This case seems to be unique because, to the best of our knowledge, an arteriovenous malformation associated with precocious puberty has never been described previously.
