Erosive parapharyngeal space XXXX .

@entity1 @entity5 @entity2998 @entity3224 @entity44
An erosive @entity44 of the parapharyngeal space is described. Our @entity1 at three months of age presented with an eight-week history of torticollis. Diagnosis was strongly suggested by CT scan which clearly demonstrated bony, fluid and intermediate densities suggestive of a @entity44 . The @entity5 had eroded the petrous bone with inferior extension to the level of the hyoid cartilage. An angiogram revealed compromise of the internal carotid artery at the skull base. Surgical resection at five months removed the @entity5 from the right parapharyngeal space and included a portion of the petrous bone involving the contents of the middle ear and extending to the base of skull. All vital structures including the @entity2998 and vagus nerve preserved. An intraoperative CSF leak was controlled with a muscle plug. To our knowledge, such an extensive @entity44 eroding the petrous bone and base of skull, presenting as a neck mass, is the first reported case in the literature. The value of a CT scan as an @entity3224 in diagnosis of this @entity5 is stressed.
