Ultrasonic tissue characterization of malignant lymphoma.
The echographic characteristics and ultrasonic tissue characterization of malignant lymphoma are reported. The patient was a 72-year-old man with stage IV malignant lymphoma of medium cell type and had lymphomatous involvements in the liver, the spleen, and peripancreatic, para-aortic, hepatic and splenic hilar lymph nodes. The echo-characteristics were hypoechoic in nature in all these involved lesions and the histologic specimen at the border between the lymphoma lesion and the liver was examined as well as the peripancreatic lymph node from the viewpoint of the ultrasonic tissue characterization. It was concluded that the rich cellularity in the homogeneous nature when compared with the surrounding structure, can produce hypoechoic lesion in routine clinical echograms.
