Abstract

Hepatic atypical lymphoid hyperplasia is a rare borderline lymphoproliferative lesion. Unlike benign reactive lymphoid hyperplasia, atypical lymphoid hyperplasia has the potential to transform into lymphoma. We describe MRI and FDG PET/CT findings in a case of hepatic atypical lymphoid hyperplasia. The hepatic lesion appeared as a small solid mass with central necrosis and low-grade enhancement on MRI and showed intense FDG uptake with SUV max of 8.2, mimicking malignancy. This case suggests that hepatic atypical lymphoid hyperplasia should be considered as a rare differential diagnosis in patients with focal hypermetabolic hepatic lesions.

FDG PET/CT显示肝脏非典型淋巴样增生。

肝脏非典型淋巴样增生是一种罕见的交界性淋巴增生性病变。与良性反应性淋巴样增生不同，非典型淋巴样增生有可能转变为淋巴瘤。我们描述一个肝脏非典型淋巴样增生病例的MRI和FDG PET/CT表现。肝脏病变表现为一个小的实心肿块，中心坏死，MRI低级别增强，显示强烈的FDG摄取，SUVmax为8.2，模拟恶性肿瘤。本病例提示，在局灶性高代谢性肝脏病变患者中，肝脏非典型淋巴样增生应被视为罕见的鉴别诊断。
