Core Tip

Core Tip: A 43-year-old female patient was diagnosed with primary pulmonary synovial sarcoma (PPSS) and nine months later, metastases were found in the chest wall and both kidneys. There are very few imaging reports on PPSS. This study summarizes the imaging findings of PPSS and its secondary distant metastases. PPSS is often manifested as irregular tumor and calcification, and the metastases have extremely low echo on ultrasonography. Contrast-enhanced ultrasound indicates that the arterial phase of tumor metastases shows rapid centripetal high enhancement, manifested as “fast forward and fast regression”.
