Sphenoid mucocele with intracranial invasion secondary to nasopharyngeal acinic cell carcinoma

We present a case of sphenoid mucocele with large invasion of the middle cranial fossa, secondary to a nasopharyngeal acinic cell carcinoma, occurring in a 52‐year‐old man. To the best of our knowledge, this association has not been reported so far. We discuss the importance of imaging techniques in delineating the relationship between the two lesions, as long as the clinical and therapeutic problems related both to sphenoid mucocele and acinic cell carcinoma.
