Fungal Sinusitis

1-Click on the image to enlarge.
2-Then,localise the lesion you see(where is it).
3-It is a completely opacified left maxillary sinus and mucosal thickening of the right maxillary sinus.
4-Then ,characterise these lesions
When we look to the density of left sinus component and that of right sinus mucoca you can easly suggest that these densities are hyper dense if compared to surrounding soft tissue.
As a rule hyperdense opacified sinus is a benign sign which could be due the following
-Inspissated secretions.
-Fungal or
-Blood
After contrast injection no enhancement noted denoting no masses.
According to the history of the patient we can know the exact cause of this appearance.
In such a case bilaterality of the lesions with right mucosal thickening can exclude blood in case of absence of history of trauma.On the other hand,absence of history of immuno suppresive disease could exclude fungal infection and so on.

2- First,localise the lesion (where is it).
3-The lesion is in the region of the right temporal bone.
4-Then,characterise this lesion as follow
-In T1 MRI,it appears hypo intense.
-In T2 MRI,it appears hyper intense.
-In T1 MRI with contrast,it showed contrast enhancement.
-In Diffusion MRI,it showed no changes.
5-Impression:
A lesion in this region with contrast enhancement and no changes of its signal
on diffusion sequence should be infection and not a cholesteatoma.

2-Patient with relapsing cholesteatoma.
3-First localise the lesion(where is it)
4-The answer of this question =it is located at the site of operation on the left side.
5-Secondly,characterise this lesion as follow
In T1 MRI sequence,the lesion is hypo intense.
In T2 MRI sequence,the lesion is hyper intense
In T1 sequence with contrast injection, no enhancement seen
In Diffusion sequence,the lesion is hyper intense.
6-Impression:
A lesion in this location with no enhancement and showed hyper intensity on diffusion
sequence should be a cholesteatoma.
