CT, MRI and gallium SPECT in the diagnosis and treatment of petrous apicitis presenting as multiple cranial neuropathies

초록

We present a rare case of petrous apicitis initiated by middle ear inflammation in a diabetic patient with multiple cranial neuropathies for early diagnosis of this potentially life-threatening condition. The lesion appeared as opacification of middle ear, petrous apex with aggressive bony destruction on CT and diffuse petrosal T-1 hypointensity with adjacent soft tissue propagation on MRI. Gallium-67 single-photon emission computed tomography (SPECT) scan also contributed to evaluate response to therapy.
