Prostate sarcoma is a rare malignancy with an extremely poor prognosis. The extremely low morbidity and atypical clinical symptoms contribute to a missed diagnosis. The typical features of prostate sarcoma in transrectal ultrasound (US) and magnetic resonance imaging, such as a markedly enlarged volume and irregular prostatic contours, cannot usually be found until dysuria or even uroschesis occurs, and may then be too late to treat. However, there appears to no specific tumor marker for the disease in the serum. The present study reports a case of a young male patient who was diagnosed with prostate rhabdomyosarcoma. This was, to the best of our knowledge, the first case of this diagnosis using contrast-enhanced US (CEUS) when the symptoms were not severe. In this case, the intralesional non-enhancement areas and rim-like hyper-enhancement around the lesion were considered to be the main CEUS features of prostate rhabdomyosarcoma. The present study also reviews the associated literature.
前列腺肉瘤是一种罕见的恶性肿瘤，预后极差。其发病率极低且临床症状不典型，容易导致漏诊。经直肠超声（US）和磁共振成像中前列腺肉瘤的典型特征，如体积明显增大和前列腺轮廓不规则，通常在出现排尿困难甚至尿潴留时才能发现，此时治疗可能为时已晚。然而，血清中似乎没有针对该疾病的特异性肿瘤标志物。本研究报告了一例年轻男性患者，被诊断为前列腺横纹肌肉瘤。据我们所知，这是首例在症状不严重时使用超声造影（CEUS）进行该诊断的病例。在该病例中，病灶内无增强区和病灶周围的环状高增强被认为是前列腺横纹肌肉瘤的主要CEUS特征。本研究还回顾了相关文献。
