To elucidate the cause of the increase in the echogenicity of the pancreas in the elderly, the ultrasonograms of 116 patients were studied for echogenicity, and the echogenicity of the ultrasonograms in living patient and that of ultrasonograms of immersed autopsied pancreas were compared with the histological findings.In approximate 65% of the patients, the echogenicity of the pancreas was greater than that of the liver, and 24% were remarkably greater than it. In comparison with the echogenicity and histological findings, it was revealed that the level of fatty replacement among the high echogenicity group was significantly greater than that in the low echogenicity group, and there was a close relationship between echogenicity of the pancreas and fatty replacement of this tissue. However, there was no relationship between echogenicity of the pancreas and pancreatic fibrosis.These results suggest that the increased echogenicity of the pancreas in the elderly is attributable to the histological increase in fatty replacement of the pancreas.
