We report a case of isolated posterior tibial B-cell lymphoma of the posterior tibial nerve presenting as tarsal tunnel syndrome. This diagnosis was considered because of the clinical presentation and electrophysiologic abnormalities. It was further confirmed by the magnetic resonance imaging findings of the ankle and tissue pathologic findings. Whole body positron emission tomography confirmed this to be a localized lymphoma involving the peripheral nerve. The patient underwent chemotherapy with complete tumor resolution. She had had no relapse after 8 months of follow-up. Isolated peripheral nerve lymphomas are very rare, and involvement of the posterior tibial nerve has not been previously reported. Furthermore, the present case report highlights the importance of the clinical examination in the diagnosis of tarsal tunnel syndrome before performing surgical decompression.
我们报告一例表现为跗管综合征的胫后神经孤立性B细胞淋巴瘤病例。基于临床表现和电生理异常考虑该诊断。踝关节磁共振成像结果和组织病理学结果进一步证实了这一诊断。全身正电子发射断层扫描证实这是一种累及周围神经的局限性淋巴瘤。该患者接受化疗后肿瘤完全消退。随访8个月后未复发。孤立性周围神经淋巴瘤非常罕见，此前尚无胫后神经受累的报道。此外，本病例报告强调了在进行手术减压之前，临床检查在跗管综合征诊断中的重要性。
