[Megavisceral syndrome. Report of 2 cases]

Two patients with splanchnomegaly are presented, and it is proved through experimental, clinical, anatomicopathological, and epidemiological investigations that Trypanosoma cruzi--the etiological agent of Chagas' disease--causes splanchnomegaly in those countries where this disease is endemic. It is neither assured nor denied that Trypanosome cruzi has been the causal agent of splanchnomegaly in the studied patients. It is suggested that in further investigations this problem may be cleared up.
