The fat-forming variant of solitary fibrous tumour (SFT) was previously called lipomatous haemangiopericytoma and is a rare variant of solitary fibrous tumour. It predominantly occurs in the deep soft tissues of the retroperitoneum and thigh. Only a handful of cases involving the perineum, spine, thoracic wall and pelvic cavity have been reported in the radiological literature and the fat-forming variant of SFT involving the pleura has not been previously reported. Herein, we report the CT findings of a case of the fat-forming variant of SFT involving the pleura that was treated by excision. Chest CT showed a large lobulated heterogeneous fatty mass with a multifocal enhancing soft-tissue component in the left lower hemithorax. Although rare, the fat-forming variant of SFT of the pleura should be added to the differential diagnosis of fat-containing pleural soft-tissue tumours.
孤立性纤维瘤（SFT）的脂肪形成变体以前称为脂肪瘤性血管外皮细胞瘤，是 SFT 的一种罕见变体。它主要发生在腹膜后和大腿的深部软组织中。在放射学文献中仅报道了少数涉及会阴、脊柱、胸壁和盆腔的病例，而涉及胸膜的 SFT 脂肪形成变体以前尚未报道。在此，我们报告了一例经切除治疗的胸膜脂肪形成变体 SFT 的 CT 发现。胸部 CT 显示左下半胸有一个大的分叶状不均匀的脂肪肿块，伴有多个局灶性强化的软组织成分。尽管罕见，但胸膜脂肪形成变体 SFT 应添加到含脂肪性胸膜软组织肿瘤的鉴别诊断中。
