Segmental testicular infarction is a rare clinical condition most often seen as acute unilateral scrotal pain. Segmental testicular infarction should be suspected in patients with scrotal pain; when an ultrasound shows hypoechoic or mixed echogenic lesions within the testicular parenchyma; contrast-enhanced ultrasound shows a little or no contrast filling, along with negative multiple tumor markers. This report presents a 60-year-old male who presented with sudden onset of left testicular pain with no apparent cause. Emergency Doppler ultrasound, contrast-enhanced ultrasound, and laboratory tests showed findings characteristic of Segmental testicular infarction. The patient the final diagnosis was based on a combination of clinical findings (regression or cessation of symptoms, no tumor marker abnormalities, no palpable testicular mass) and ultrasound evidence of improvement (size reduction or shape change from oval to wedge) during a follow-up period of at least 3 months.
节段性睾丸梗死是一种罕见的临床病症，最常见的表现为急性单侧阴囊疼痛。对于阴囊疼痛的患者，若超声显示睾丸实质内有低回声或混合回声病变；超声造影显示造影剂少量充盈或无充盈，且多项肿瘤标志物为阴性，则应怀疑节段性睾丸梗死。本报告介绍了一名60岁男性，他突然出现左侧睾丸疼痛，无明显诱因。急诊多普勒超声、超声造影及实验室检查显示出节段性睾丸梗死的特征性表现。该患者的最终诊断基于临床症状（症状消退或停止、肿瘤标志物无异常、未触及睾丸肿块）以及至少3个月随访期内超声显示的改善证据（大小缩小或形状从椭圆形变为楔形）的综合判断。
