[Radiologic diagnosis of non-Hodgkin's lymphoma in abdominal and retroperitoneal sites]

A total of 112 patients with non-Hodgkin's lymphomas of abdominal and retroperitoneal localization were examined by the ultrasonic and x-ray methods, in 83 of them x-ray computer-aided tomography was used. Angiographic examinations and puncture biopsy monitored by US or x-ray CAT were carried out if indicated. The authors discuss the problems of ultrasonic and x-ray semeiotics of the lymphomatous involvement of the lymph nodes, spleen, gastrointestinal tract. They claim that USE, permitting the specification of further plan of examination of each patient, and x-ray examination as a method to assess the gastrointestinal status are the optimal methods for the primary diagnosis of non-Hodgkin's lymphomas. US data may prompt further application of x-ray CAT, whose results will supplement the US findings. Angiographic examinations should be carried out only in the most difficult diagnostic situations, bearing in mind the invasive nature of the method and its high price.
