(A1) Pathological section of adenoid cystic carcinoma of the right middle lung. (A2) Pathological section of the spleen metastasis. (A3) Pathological section of the left lower lung metastasis. (B1) The spleen metastasis. (B2) The left lower lung metastasis (Yellow arrow). (B3) The PET-CT in December 2019 showed tumor recurrence in the right hilus pulmonis (White arrow). The bronchoscope finds adenoid cystic carcinoma cells at the end of the right main bronchus. (B4) The liver metastasis (Blue arrow). (C) Changes of the lesions at hilum of right lung (Blue arrow) in different periods. Comparison of the conditions 9 months before and 6 months after the targeted therapy showed that no significant change occurred to the lesions. (D) Changes of the left hilar lymph node in different periods. In 2016, PET-CT showed no lymph node at the hilum of left lung. Comparison of the conditions 9 months before and 6 months after the targeted therapy showed that no significant change occurred to the size of left hilar lymph node (Yellow arrow). (E) Changes of liver metastasis (Red arrow) in different periods.

In 2016 she underwent wedge resection for left lower lung metastasis due to metastasis of ACC of the left lower lung that was detected via periodic examination (Figures 1A1-A3,B1,B2). In December 2019 CT depicted hepatic nodules, and positron emission tomography-CT suggested recurrence of the right hilar tumor, left hilar lymph node metastasis, and hepatic metastasis (Figures 1B3,B4).
