Vascular compression of the oculomotor nerve disclosed by thin-slice magnetic resonance imaging.
OBJECTIVE
To describe the thin-slice magnetic resonance imaging features of vascular compressive oculomotor nerve paresis.


METHODS
We performed thin-slice (2 mm thick) magnetic resonance imaging of the brainstem in a 74-year-old woman with right partial oculomotor nerve paresis using spoiled gradient recalled acquisition in the steady state.


RESULTS
Thin-slice magnetic resonance images disclosed that the right oculomotor nerve was compressed and dislocated superiorly and laterally by the tortuous basilar artery. No other abnormalities were observed.


CONCLUSIONS
This is the first case report of vascular compressive oculomotor nerve paresis disclosed by thin-slice magnetic resonance imaging.
