Cyst wall vascularity not evident on abdominal aortography was demonstrated by selective magnification angiography in two children with complicated solitary, nonparasitic liver cysts. In one, its character and degree led to a false diagnosis of tumor. The observed mural vascularity probably reflected secondary changes of inflammation and necrosis in one case and prior surgery in the other case. Histologic findings in previously reported cases, however, indicate that, contrary to accepted angiographic beliefs, mural vascularity also occurs in many noncomplicated, simple liver cysts. Angiographers should be aware of this, and that the possibility exists of visualizing this mural vascularity by selective magnification angiography.
