FIG 20. ICGA is necessary not only for the diagnosis but also for continuous monitoring of the disease, which may present polyp relapse or the appearance of new polyps from the BVN, with phases of quiescence, exudation or hemorrhage. A. Late phases of FA showing the hyperfluorescent PEDs. B. ICGA image. B1 and B2. Only the PEDs are seen, and the BVN alteration is noted in early phases with ICGA. B3 and B4. Formation of polyps from the BVN, visible with ICGA 6 months later.
