The uterine doughnut: potential pitfall for technetium-99m gastrointestinal bleeding study.
A case of intense uterine hyperemia secondary to recent pregnancy, the so-called uterine "doughnut" sign, is presented as a potential pitfall in the evaluation of gastrointestinal bleeding. Delayed imaging helped in evaluating the lack of serial change in appearance and the failure of progression of the scintigraphic abnormality.
