Pulmonary artery intimal sarcomas (PAIS) are often misdiagnosed as pulmonary embolisms (PE) as their clinical findings and imaging findings are similar. However, given the clinical outcome of both diseases is different in its prognosis, accurate and rapid diagnosis is mandatory. This is a case report of a histologically-proven PAIS which was initially treated as a PE. The color-coded iodine map using dual-energy computed tomography (dual-energy CT iodine map) well reflected the distribution of the tumor consistent with fluoro-2-deoxyglucose-uptake region using positron emission tomography/CT. This case demonstrates the potential of using dual-energy CT iodine map to differentiate PAIS from PE.
Use of a dual-energy computed tomography iodine map to visualize a pulmonary artery intimal sarcoma may provide useful diagnostic information.
肺动脉内膜肉瘤（PAIS）常被误诊为肺栓塞（PE），因为它们的临床表现和影像学表现相似。然而，鉴于这两种疾病的临床结局在预后方面有所不同，准确快速的诊断是必不可少的。这是一例经组织学证实的PAIS病例报告，该病例最初被当作PE进行治疗。使用双能计算机断层扫描的彩色编码碘图（双能CT碘图）很好地反映了肿瘤的分布，与使用正电子发射断层扫描/计算机断层扫描的氟代脱氧葡萄糖摄取区域一致。本病例证明了使用双能CT碘图鉴别PAIS和PE的潜力。
使用双能计算机断层扫描碘图可视化肺动脉内膜肉瘤可能提供有用的诊断信息。
