Incidental paranasal sinus abnormality on cranial computed tomography in a Nigerian population

{Table 2} Mucosal abnormality was commonest in the anterior ethmoids (34%), followed by the maxillary antrum (30%), frontal sinus (13%) posterior ethmoids (12%), and least occurring in the sphenoidal sinus (11%). Because of the high sensitivity of the CT scan for mucosal inflammation in the paranasal sinuses, it is indeed possible that the CT scan can identify "incidental" mucosal findings that do not represent true "sinus" disease. [...]incidental sinus disease is relatively common on routine cranial CT scans among Nigerian adults.
