PURPOSE: The purpose was to evaluate three-dimensional magnetic resonance imaging with contrast (3D-CEMRI) in displaying peripheral oculomotor nerve (PON) and diagnosing peripheral oculomotor nerve diseases (POND). MATERIALS AND METHODS: The MRI findings of 80 patients with POND were reviewed and compared with digital subtraction angiography (DSA), operative or pathological results, and final clinical diagnosis. RESULTS: Twenty-three aneurysms (23/26) confirmed by DSA were detected with Magnetic Resonance Angiography (MRA). Twenty-five inflammatory lesions, 14 malignant lesions, and 5 benign lesions involving PON were shown with 3D-CEMRI corresponding with clinical diagnosis and pathology. Another 13 (13/80, 16.03%) cases were negative on MRI. CONCLUSION: 3D-CEMRI with MRA could show and diagnose the majority of the diseases involving PON.
