Abstract：
Neurolymphomatosis (NL) is a rare disease. Ultrasound (US) plays a crucial role in diagnosing and following up the NL.
A 59-year-old man was hospitalized with acute pain in the left upper extremity. Ultrasound revealed segmental swelling of multiple nerves around his left elbow with abundant blood flow signals. Contrast-Enhanced Ultrasound (CEUS) showed a rapid, complete and homogenous enhancement in the nerve lesions in the early arterial phase. The NL was confirmed by imaging and flow cytometry, and he accepted chemotherapy. The posttherapeutic ultrasound showed that the nerves in the left upper limb were basically normal. Unfortunately, the patient died of cerebral metastasis in 5 months.
The nerve US and CEUS can show specific manifestations and provide more diagnostic information about NL.

摘要：
背景：神经淋巴瘤病（NL）是一种罕见的疾病。超声（US）在NL的诊断和随访中起着至关重要的作用。
方法：一名59岁男子因左上肢急性疼痛住院。超声显示左肘周围多个神经节段性肿胀，血流信号丰富。对比增强超声(CEUS)显示,在动脉早期，神经病变的完整和均匀增强。通过成像和流式细胞术证实了NL，他接受了化疗.治疗后超声显示左上肢神经基本正常。不幸的是,患者在5个月内因脑转移死亡。
结论：神经US和CEUS可以显示特定的表现，并提供有关NL的更多诊断信息。
