[Prevalence of visceromegalies in necropsies carried out in Triângulo Mineiro from 1954 to 1988].

One thousand seven hundred and eight chronic chagasic post-mortem examinations studied from a total of 4690 autopsies performed at our Institution. Two hundred and seventy-three chagasic had megas. Megacolon was the most frequent, followed by megaesophagus. Megacolon associated with megaesophagus was the third most common finding. Our data are discussed and compared with the literature. Megacolon and megaesophagus were more prevalent in man, as shown by other workers. Higher parasitemia perhaps could explain this finding.
