Diplopia in childhood secondary to sphenoidal sinusitis

MR imaging in coronal section; fluid collection in sphenoidal sinus is hyperintense in T2-weighted images (A) and hypointense in T1 weighted images (B) sequences. Contrast enhancement is easily visible after contrast study (C). Lesion lies closely adjacent to left cavernous sinus.

After treatment, sphenoidal sinus has normal structure and consistency in axial CT images (bone window). In addition, bony septa lying in sphenoidal sinus attracts attention.
