Solitary fibrous tumour of the pleura (SFTP) accounts for < 5% of pleural tumours, and the ultrasound (US) features of giant SFTP (> 20 cm) remain unknown. We present the case of a woman diagnosed with giant SFTP associated with Doege-Potter syndrome, who experienced dyspnea and recurrent hypoglycemia. Chest x-ray revealed a large left hemithorax opacity, initially misdiagnosed as massive pleural effusion, leading to an inappropriate thoracentesis. Subsequent US demonstrated a large heterogeneous mass with intralesional cystic changes and calcifications, which lacks respiratory movement. Computed tomography showed a 27 cm × 15 cm × 12 cm left pleural mass. US-guided biopsy confirmed SFTP. Complete surgical resection resolved all symptoms, including hypoglycemia. This case highlights the distinct US features of giant SFTP, which differ from smaller SFTP reported in the literature. Awareness of the variable US characteristics of SFTP across different sizes can enhance accurate diagnosis and facilitate management.
胸膜孤立性纤维瘤（SFTP）占胸膜肿瘤的比例不到5%，而巨大型SFTP（>20cm）的超声（US）特征尚不清楚。我们报告一例诊断为与多伊格-波特综合征相关的巨大型SFTP的女性病例，该患者出现呼吸困难和反复低血糖。胸部X线显示左半胸大片致密影，最初误诊为大量胸腔积液，导致不适当的胸腔穿刺。随后的超声检查显示一个巨大的异质性肿块，伴有瘤内囊性改变和钙化，无呼吸运动。计算机断层扫描显示一个27cm×15cm×12cm的左胸膜肿块。超声引导下活检确诊为SFTP。完整的手术切除解决了所有症状，包括低血糖。该病例突出了巨大型SFTP独特的超声特征，与文献报道的较小的SFTP不同。认识到不同大小的SFTP的超声特征差异，可提高准确诊断并便于治疗。
