ABSTRACT Primary cardiac tumors are rare, with an incidence between 0.0017 and 0.19%, and are asymptomatic in up to 72% of cases. Approximately 75% of tumors are benign, and nearly 50% of these are myxomas. Concerning location, 75% of myxomas are in the left atrium, 15 to 20% in the right atrium, and more rarely in the ventricles. The finding of cardiac myxomas usually implies immediate surgical excision to prevent embolic events and sudden cardiac death. Reports with documented growth rate are rare, and the actual growth rate remains a controversial issue. We report the rapid growth rate of a right atrial myxoma in an oligosymptomatic 69-year-old patient, with negative previous echocardiographic history in the last two years, who refused surgery upon diagnosis, enabling monitoring of myxoma growth.

O divertículo de Meckel (DM) é um vestígio remanescente do ducto vitelino que se forma entre a oitava e nona semanas de gestação. É uma manifestação relativamente comum na população geral (2%), no entanto, raramente desenvolve sintomas. Quando desenvolve sintomas a hematoquezia indolor é o sintoma mais prevalente. A investigação da hematoquezia dolorosa requer a exclusão de diversas patologias gastrointestinais. No presente artigo relatamos o caso de um paciente com DM de apresentação clínica e epidemiologia atípicas e sua investigação, assim como uma revisão de literatura sobre os métodos diagnósticos para se chegar ao DM.
Meckel's diverticulum (DM) is a remnant of the vitelline duct that forms between the eighth and ninth weeks of gestation. It is a relatively common manifestation in the general population (2%), however, it rarely develops symptoms. When symptoms develop, painless hematochezia is the most prevalent symptom. The investigation of painful hematoquezia requires the exclusion of several gastrointestinal pathologies. In the present article we report the case of a patient with atypical clinical and epidemiology DM presentation and it´s investigation, as well as a literature review on the diagnostic methods to arrive at DM.
