Abstract
Sphenoid sinuses are carved into the body of the sphenoid bone. They are probably the most variably pneumatized structures of the skull. They begin their pneumatization at the age of three and finished at adolescence. Several anatomic variants of sphenoid sinuses have been described in the literature. The agenesis of sphenoid sinuses in adults is very rarely found. We report two incidental cases of sphenoid sinuses agenesis discovered on CT scan in Benin, West Africa.
Highlights
Open Access have been described as the most variable cavities of the human body [1]
We present two consecutive cases of bilateral agenesis sphenoidal sinuses fortuitously discovered by using Computed Tomography (CT-scan) in the Radiology Department of the National and University Teaching Hospital Hubert Koutoukou Maga of Cotonou in Benin (CNHU/HKM)
Computed tomographic scanning was performed in the Radiology Department of the CNHU / HKM on EMOTION SIEMENS 16 slices
Summary
A 66-year-old woman with a history of high blood pressure was received in the Figure 1. CT in bone window in axial cuts shows comparison of case 1 (a): agenesis of sphenoid sinuses and (b) normal pneumatization of sphenoid sinuses (arrows). Radiology Department of CNHU/HKM on June 25, 2016; for the exploration of a left hemi-corporeal deficit. Computed tomographic examination revealed an ischemic stroke of the territory of the right posterior artery. The visualization of the bone window found an absence of the pneumatisation of the sphenoid sinuses (Figure 3).
