| Abstract: | In order to determine the value of CT in detecting lymphomatous involvement of the liver, 57 autopsied cases (48 cases of non-Hodgkin lymphoma and 9 of Hodgkin's disease) were analyzed in detail. Additionally, 90 recent cases of abdominal CT with liver study in the initial staging were reviewed and 6 cases in which the liver had been examined within 2 weeks before autopsy were compared for macroscopic and pathologic findings. The following results were obtained. Autopsy findings in 57 cases of malignant lymphoma. (1) Hepatic involvement was demonstrated in 56% of the patients with non-Hodgkin lymphoma and in 67% of those with Hodgkin's disease. Of these patients with hepatic involvement, intrahepatic nodular lesions over 1.0 cm in diameter were macroscopically identified in 22% of the cases of non-Hodgkin lymphoma and 33% of those with Hodgkin's disease. Lymphomatous involvements were seen in many organs in the cases of hepatic involvement. CT examinations of 90 cases for the initial staging showed no significant abnormality in the liver or spleen. Of the 6 cases in which the liver was examined by CT within about 2 weeks before autopsy, lymphomatous involvement was pathologically diagnosed in 5. Of these, only one having multiple nodules larger than the tip of a thumb was correctly diagnosed by CT. Hepatic involvement of lymphoma was thought to be the end stage, and minimal or early disease was detected in the region of Glisson's capsule. The above findings indicate that early hepatic involvement is not likely to be detected by CT at the present time. |
