Prostatic sarcoma (PS) is a very rare malignant tumor that accounts for <0.1% of prostate malignancies, and Ewing's sarcoma is an extremely rare form of PS.
We reported on a 64-year-old patient with PS and a 36-year-old patient with Ewing's sarcoma, both of whom were examined by contrast-enhanced ultrasonography (CEUS) before surgery.
The 2 cases were proven to be prostatic stromal sarcoma, which was confirmed by imaging manifestations and histopathological findings.
The 64-year-old patient underwent radical prostatectomy, and the 36-year-old patient underwent chemotherapy combined with local radiotherapy.
PS showed diffuse enlargement of the prostate on sonography, and the necrotic liquefying area within the large vessels could be clearly displayed by CEUS. CEUS can be advocated as a valuable noninvasive and safe imaging diagnosis method for PS.
前列腺肉瘤（PS）是一种非常罕见的恶性肿瘤，占前列腺恶性肿瘤的<0.1%，而尤文肉瘤是一种极其罕见的 PS 形式。
我们报告了一例 64 岁 PS 患者和一例 36 岁尤文肉瘤患者，他们在手术前均接受了超声造影（CEUS）检查。
这 2 例均被证实为前列腺间质肉瘤，通过影像学表现和组织病理学发现得到证实。
64 岁患者接受了根治性前列腺切除术，36 岁患者接受了化疗联合局部放疗。
PS 在超声检查中表现为前列腺弥漫性增大，CEUS 可清晰显示大血管内的坏死液化区。CEUS 可以作为一种有价值的无创、安全的 PS 影像学诊断方法。
