Intracranial Complication of Rhinosinusitis from Actinomycosis of the Paranasal Sinuses: A Rare Case of Abducens Nerve Palsy
Figure 2
Maxillofacial and brain CT (a, b) and MRI (c, d). (a) Axial CT with contrast medium and (c) MRI-T1 weighted sequence showing abnormal extension of the left sphenoid sinus with thinning of the posterior and lateral bony walls (arrows) and compression of the temporal lobe (asterisk). (b) Coronal CT showing opacification of almost all paranasal sinuses associated with a focal erosion of the papyracea lamina (arrows). (d) Coronal T2-weighted MRI image showing temporal lobe compression (asterisk), while the left abducens nerve and cavernous sinus are not clearly recognizable.
