A 46-year-old woman with advanced ovarian carcinoma had progressive dyspnea and was evaluated with ventilation and perfusion lung imaging. A characteristic pattern of multiple branching perfusion defects of a segmental nature on the perfusion scan suggested tumor microembolism and lymphangitic carcinomatosis. However, in this case, this pattern was associated with pulmonary thromboembolism and was documented by the post mortem examination. Pulmonary thromboembolism should be included among the differential diagnoses in a patient with clinical symptoms and a perfusion scan that reveals multiple branching perfusion defects.
一名46岁晚期卵巢癌女性出现进行性呼吸困难，接受了肺通气和灌注显像评估。灌注扫描显示节段性多发分支灌注缺损的特征性表现，提示肿瘤微栓塞和淋巴管癌病。然而，在该病例中，这种表现与肺血栓栓塞症相关，尸检证实了这一点。对于有临床症状且灌注扫描显示多发分支灌注缺损的患者，鉴别诊断应包括肺血栓栓塞症。
