Primary pulmonary intimal sarcoma is rare. Differentiating it from pulmonary thromboembolism is difficult because of similarities in clinical symptoms and imaging findings. Positron-emission tomography-computed tomography has been useful for diagnosing primary pulmonary intimal sarcoma. We describe a rare case of primary pulmonary intimal sarcoma that showed no abnormal F-fluorodeoxyglucose uptake on positron-emission tomography. We resected the mass and performed right ventricular outflow tract reconstruction. Proper diagnosis is necessary to determine appropriate therapy, Clinicians must consider the possibility of primary pulmonary intimal sarcoma even if imaging findings are inconsistent with the disease.
原发性肺内膜肉瘤很罕见。由于临床症状和影像学表现相似，将其与肺血栓栓塞症区分开来很困难。正电子发射断层扫描-计算机断层扫描对诊断原发性肺内膜肉瘤很有用。我们描述了一例罕见的原发性肺内膜肉瘤病例，该病例在正电子发射断层扫描中未显示异常的氟脱氧葡萄糖摄取。我们切除了肿块并进行了右心室流出道重建。正确的诊断对于确定适当的治疗方法很有必要，即使影像学表现与该病不一致，临床医生也必须考虑原发性肺内膜肉瘤的可能性。
