Abstract

Here, we report a case of hepatoblastoma metastasis to the left pulmonary artery which was resected by left lingular segmentectomy plus left lower lobectomy in 5-year-old girl. She had previously undertaken right upper lobectomy and multiple lung partial resections on bilateral lungs as hepatoblastoma metastatectomies. Prediction of postoperative pulmonary function based on perfusion scan merged with CT image and the measurement by CT volumetry, showed that left lingular segmentectomy plus left lower lobectomy could preserve 78% of the preoperative functional values and resection was done. Three weeks after the operation, her condition recovered to the preoperative level. Pathological examination showed that the metastasis was tumor embolism of hepatoblastoma which extended into the pulmonary arterial wall, which to our knowledge, has not been previously reported.
