title: [Atypical debut of symptoms of cholangiocarcinoma].
abstract: Malignancy of the sphenoid sinus is rare and metastasis from a cholangiocarcinoma (CC) to this location is even rarer. We present a 74-year-old female with CC metastasis to the sphenoid sinus. This case demonstrates that metastases to the sphenoid sinus occur and that the tumour can have its origin far from the head and neck region. Thus, the possibility of metastasis must always be considered when discovering a tumour in the sphenoid sinus.
