Brainstem, skull base, and pituitary gland in , granulomatosis with polyangiitis causing cavernous sinus syndrome and diabetes insipidus (MRI)
Coronal contrast-enhanced fat-saturated T1-weighted MRI of the brainstem, skull base, and pituitary gland in a woman with granulomatosis with polyangiitis causing cavernous sinus syndrome and diabetes insipidus. There is pathological enhancement of the cavernous sinus, pituitary gland, and pituitary stalk (arrow). The abnormalities are nondiscrete and radiologically inconsistent with a microadenoma or invasive macro adenoma of the pituitary gland.
