Contrast-enhanced ultrasound diagnosis of prostatic sarcoma: Two case reports
1Department of Ultrasound Medicine, Inner Mongolia Autonomous Region People's Hospital, Hohhot, Inner Mongolia, 010017, China.
Rationale:
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.
Patient Concerns:
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.
Diagnoses:
The 2 cases were proven to be prostatic stromal sarcoma, which was confirmed by imaging manifestations and histopathological findings.
Interventions:
The 64-year-old patient underwent radical prostatectomy, and the 36-year-old patient underwent chemotherapy combined with local radiotherapy.
Outcomes:
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.
