The diagnostic challenge of identifying the nature of sinonasal masses before treatment would guide therapeutic strategies. Our objective was to evaluate the accuracy of computed tomography in the preoperative diagnosis of sinus masses at the Central Hospital of Yaoundé. Method: A retrospective chart review was conducted;CT scan reports and pathology reports of patients operated for sinonasal masses between January 2012 and November 2022 were compared. Results: Forty-five patients met the inclusion criteria for the study. The average age was 39.98 ± 18.34 years, with extremes of 15 and 87 years. The sex ratio H/F is 0.76 with a female predominance. The median time to consultation was 14 [12 - 18] months, with extremes of 11 and 36 months. The most frequently encountered histological type was benign tumors with sinonasal polyposis (PNS) in the lead, i.e. 34.1% of cases. The types adenocarcinoma, adenoid cystic carcinoma and non-Hodgkin’s lymphoma were represented equally in 6.8% of cases. Management was dominated by Caldwell-Luc surgery, i.e. 59.1% of cases. The frequency of disease recurrence after surgical treatment was 18.2%. As for the mortality rate, it was 11.4%. The concordance rate of the character of malignancy on imaging compared to histology was 90.9%. This level of concordance was statistically significant according to the Gamma test (p Conclusion: Preoperative CT scans correlate with histology and have a prognostic role in surgically treated sinonasal masses.展开更多

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
