| Abstract: | Trotter's syndrome is a clinical triad of unilateral deafness, neuralgia affecting branches of the trigeminal nerve, and defective mobility of the soft palate, which is caused by malignant tumors involving the lateral pharyngeal recess (Rosenmüller's fossa). It is an ominous presentation, which can masquerade as dental or masticatory pain. Computerized tomography (CT) can be used not only to explain the anatomic basis of Trotter's syndrome but also to determine the extent and distribution of the malignant tumor involved. The advantages of CT over conventional radiography are illustrated by a case of adenoid cystic carcinoma that presented as Trotter's syndrome. Perineural invasion by tumor is shown on the gross level for the first time with CT, and important diagnostic considerations, which may aid in the early diagnosis of future cases, are discussed. |
