Analysis of Imaging Findings in a Patient with Squamous Cell Carcinoma of the External Auditory Canal Metastatic to the Dura with Trigeminal Nerve Involvement.
We report the case of a 56-year-old female recently diagnosed with well-differentiated squamous cell carcinoma of the external auditory canal. The patient underwent an 18F-fluorodeoxyglucose positron emission tomography/computed tomography for staging assessment. This examination revealed intense uptake in the right ear canals, tympanic cavity, eustachian canal, parapharyngeal area, and infratemporal fossa. Notably, we identified intracranial dural metastasis, which represents an uncommon site for metastatic spread in general.
