Mucosal melanoma of the eustachian tube is a rare and highly malignant tumour. Local radical resection combined with radiotherapy and systemic chemotherapy is a classic treatment strategy for this tumour. The internal carotid artery (ICA) is easily damaged when this tumour is removed. Once the ICA ruptures and causes haemorrhage, it can be fatal. We report a case of mucosal malignant melanoma of the eustachian tube with ICA rupture and haemorrhage in a 62-year-old woman 3 days after resection of the tumour. After successful emergency endotracheal intubation, anti-shock treatment was performed. Further, the ICA was examined using digital subtraction angiography under general anaesthesia and the bleeding site was embolized. The patient recovered uneventfully after surgery and was discharged from hospital without hemiplegia, aphasia, or other intracranial complications. Because of economic reasons, the patient discontinued comprehensive treatment after being discharged from the hospital. Finally, she developed bone and kidney metastases 8 months after surgery and died of distant metastases 1.5 years later. When removing eustachian tube lesions, the ICA must be particularly protected. Once the ICA ruptures and there is postoperative haemorrhage, prevention of airway asphyxia, timely anti-shock treatment, and emergency digital subtraction angiography and vascular embolization are effective treatment methods.
