Clinically, the cases of acute pulmonary embolism after painless colonoscopy in pelvic space occupying patients are rare. In this case, a soft mass was touched by digital rectal examination. In order to clarify the mass, painless enteroscopy was performed. Cardiac arrest occurred after operation. Pulmonary arteriography showed multiple filling defects in the pulmonary aortic trunk and its branches, and pulmonary embolism was confirmed. Catheters were placed at the opening of the right pulmonary artery for local thrombolysis, and the patient was safely transferred to comprehensive ICU for further treatment. This case reminds us that for patients with pelvic space occupying lesions, we should pay attention to blood stasis among the three risk factors of thrombosis, and be alert to the risk of pulmonary embolism during painless enteroscopy, especially those who have a history of lower extremity venous thrombosis. Before painless enteroscopy, pelvic space occupying patients should have targeted examination around the focus to prevent the occurrence of pulmonary embolism.
