Sphenoethmoid Recess Pattern
Sphenoethmoid recess pattern is rather rare, consisting of sphenoid sinusitis and (not infrequently) posterior ethmoiditis, secondary to sphenoethmoid recess obstruction. Obliteration of the recess and inflammatory mucosal thickenings within sphenoid and posterior ethmoid are better depicted with axial CT (Fig. 6.11).
