Post-Therapy CT-Detected Mass in Lymphoma Patients

Abstract
Demonstration by computed tomography (CT) of enlarged nodes and/or masses in lymphoma patients has been interpreted as indicating that active disease is present. Four cases are presented in which either biopsy or laparotomy of a CT-detected mass after therapy revealed fibrous tissue with no evidence of viable neoplasm. These 4 cases demonstrate the possible pitfall of diagnosing viable lymphoma in masses detected by CT after therapy.
