case_images: CT scan of the mother 2 days after cesarean section showed no abnormalities except thickening of the tracheal wall (Figure 1(a) and (b)). The endotracheal tube was carefully withdrawn under fiberoptic bronchoscopic control to ensure a patent airway, and tumor biopsy was obtained for pathological examination (Figure 1(e) and (f)). The histopathological results, including immunohistochemistry, confirmed the tumor was malignant (Figure 1(h)), specifically an adenoid cystic carcinoma (Figure 1(i)). CT reexamination after removal of the endotracheal tube clearly demonstrated the tracheal malignancy (Figure 1(c) and (d)). Seven days following cesarean section, the patient underwent tracheal resection and reconstruction (Figure 1(g)), from which she recovered and was discharged.
