Abstract

Hepatic pseudolymphoma is a rare benign liver mass that is characterized by proliferation of non-neoplastic lymphocytes extranodally. To the best of our knowledge, only 46 cases have been reported in the English literature. We described the case of a 75-year-old woman with hepatic pseudolymphoma mimicking a hypervascular tumor. After the histological confirmation of the rectal neuroendocrine tumor, CT scan revealed a 1.0 cm-sized, poorly-defined and low-density nodule in the liver. On MRI, the hepatic nodule showed an arterial enhancement and a low-signal intensity on the hepatobiliary phase. On diffusion-weighted imaging, the hepatic nodule showed a high signal intensity on a high b-value. On fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT, it revealed a high standardized uptake value nodule. The US showed the hypoechoic nodule and the US-guided biopsy confirmed the hepatic pseudolymphoma.

간의 가성 림프종은 비종양성 림프구의 절 외 과다증식에 의해 형성되는 드문 양성 종양이다. 검색한 바에 따르면 현재까지 영문으로 46예가 보고되었다. 우리는 75세 여자환자에서 과혈관성 종양으로 오인된 간의 가성 림프종 증례를 보고하고자 한다. 조직검사상 직장의 신경내분비 암종이 진단된 후 시행한 조영증강 전산화단층촬영에서 1.0 cm 크기의 경계가 불분명하고 낮은 감쇄를 보이는 결절이 간에 관찰되었다. 자기공명영상에서는 동맥 조영기에 조영 증강을 보이고, 20분 지연기 조영 영상에서 저신호 강도를 보이며, 확산강조영상에서 고신호 강도를 보였다. Fluorodeoxyglucose (이하 FDG) positron emission tomography (PET)/CT에서는 FDG의 섭취 증가를 보였다. 초음파에서는 저에코성 병변으로 관찰되었고, 초음파 유도 하 조직검사를 통하여 간의 가성 림프종으로 확진 되었다.
