Primary symptoms of tympanic locations include hearing loss and pulsatile tinnitus. Otoscopy often shows a retrotympanic reddish mass, causing tympanic bulging. Computerized tomography scan findings include a tissue density regular mass located at the promontory and limited within the middle ear cavity. Surgical management comprises tumour excision with control of bleeding, with or without prior embolization. Aim: The aim of this presentation is to report an unusual case of tympanic paraganglioma. Case Presentation: We report the case of a 56-year-old patient whose clinical and paraclinical presentations were consistent with cholesteatoma, though a tympanic paraganglioma was discovered per-operatively. Conclusion: In some rare cases, tympanic paraganglioma can be present like a cholesteatoma.展开更多
