Examination revealed a left-sided facial nerve palsy while pure tone audiometry (PTA) showed a new left-sided deafness. MRI showed a new enhancing soft tissue lesion in the left IAM, highly suspicious of new metastases from her progressive lung cancer, which contributed to her neuro-otological symptoms. Subsequent MRI scans 4 months later also showed new brain metastases. She continued to be managed with supportive palliative care in view of her extensive disease.<\/jats:p>","DOI":"10.1136\/bcr-2017-222014","type":"journal-article","created":{"date-parts":[[2017,10,20]],"date-time":"2017-10-20T10:40:20Z","timestamp":1508496020000},"page":"bcr-2017-222014","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Lung
