The other radiological signs were heterogeneous opacities within the sinus cavity (N=5; 45.5%), local calcifications (N=4; 36.4%) and thinning of the bony walls of the sinuses (N=4; 36.4%) ( Figure 1).
MRI of the facial mass of a patient with allergic fungal rhinosinusitis: axial cut (
a,
b) and coronal cut (
c). The filling of the left maxillary sinus is presented in isosignal T1 (
a) and in hyposignal T2 or signal void (red arrow) (

In all cases, it showed T2 hypointense (signal void) images suggestive of the mycotic origin ( Figure 2).
