Abstract

Primary hepatic lymphomas are rare hepatic malignancies which are often misdiagnosed preoperatively. Early accurate diagnosis is essential as the patients can be treated successfully with chemotherapy, eluding the need for surgery. We present a case of primary hepatic lymphoma which mimicked as focal nodular hyperplasia with normal biochemical tumor markers, and F-fluorodeoxyglucose ( F-FDG) whole-body positron emission magnetic resonance showed intense FDG uptake in the large hepatic lesion. The patient subsequently underwent right hepatectomy, and histopathology revealed diffuse large B cell lymphoma.

摘要

原发性肝淋巴瘤是一种罕见的肝脏恶性肿瘤,术前常被误诊。早期准确诊断至关重要,因为患者可通过化疗成功治疗,无需手术。我们报告一例原发性肝淋巴瘤病例,其在生化肿瘤标志物正常的情况下表现为局灶性结节性增生,18F-氟脱氧葡萄糖(18F-FDG)全身正电子发射磁共振成像显示肝脏大病灶有强烈的FDG摄取。患者随后接受了右肝切除术,组织病理学显示为弥漫性大B细胞淋巴瘤。
