Pulmonary artery intimal sarcoma (PAIS) is a rare malignant tumor that presents with nonspecific symptoms and may be misdiagnosed as thromboembolic disease. We report a case of a 40-year-old female who presented with diarrhea as the initial symptom, was misdiagnosed and received thrombolytic therapy for presumed pulmonary embolism. Progressive symptoms and subsequent surgery led to the diagnosis of PAIS, and early relapse after pulmonary endarterectomy. Her survival time was 17 months after pulmonary endarterectomy. To our knowledge, diarrhea as initial manifestation of PAIS has not been described.
肺动脉内膜肉瘤（PAIS）是一种罕见的恶性肿瘤，表现为非特异性症状，可能被误诊为血栓栓塞性疾病。我们报告一例40岁女性，最初症状为腹泻，被误诊并接受了针对疑似肺栓塞的溶栓治疗。症状进展及随后的手术导致PAIS的诊断，以及肺动脉内膜切除术后的早期复发。肺动脉内膜切除术后她的生存时间为17个月。据我们所知，PAIS以腹泻为初始表现尚未见报道。
