Peripheral T‐cell lymphoma invasion of the liver: The underappreciated hypoechoic periportal cuffing on ultrasound—A case report and literature review

Abstract Liver involvement in lymphoma often manifests as nonoccupying diffuse infiltration, posing challenges in distinguishing it from primary liver disorder. Herein, we present the case of a 21‐year‐old female who underwent two separate diagnoses within a nine‐month interval before being ultimately diagnosed with peripheral T‐cell lymphoma, not otherwise specified. Our review of this case identified an ultrasound imaging feature, the hypoechoic periportal cuffing. When combined with associated increased lymphocyte count and liver enlargement, it can serve as a noninvasive suggestion for malignant disorders, in particular hemic and lymphatic diseases.
