[Apropos of a large parapharyngeal tumor. Imaging and surgery].

Based on the observation of a voluminous neurinoma of the carotid groove and of the posterior subparotid space, the authors highlight the wide range of parapharyngeal tumors and develop the anatomical bases which shed light on the clinical picture and guide the surgeon. The surgical indication must be put forth cautiously, taking into account the evolutive character of the tumor, the dangers it implies particular in Recklinghausen's disease. Modern radiology plays a major role in the diagnosis and treatment by perfectly visualizing the tumor, its vascularization and its relations with the walls and contents of the parapharyngeal spaces.
