In normal patients, the pituitary prolcatinoma was markedly enhanced on the early-phase images of the dynamic study, followed by gradual decrease of intensity throughout the dynamic study.
As compact-like cells which make up the brown areas in Cushing’s adenoma are thought to be more active in producing and secreting steroid hormones than clear-like cells, this result suggests that clinical symptoms may appear hhipofisiario in predominantly brownish adenomas than in predominantly yellowish ones.
