Results: The lesion located in the left choana region and left sphenoidal sinus of this case involved the left pharyngeal mucous space, left infratemporal fossa and its adjacent bone structure. CT showed that the rhinoscleroma in granulomatous stage was a soft mass which was irregular in shape, with a well-defined margin, inhomogeneous density and bone destruction. MRI showed heterogeneous hyperintensity on T1WI and isointensity on T2WI with an intermediate heterogeneous enhancement.

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.
