Abstract
A 45-year-old man was evaluated one week after the acute onset of pain and numbness in the right side of the face. On examination, he had a right watery eye, which has been present for several weeks (Figure 1). The patient denied history of eye trauma or previous episodes of inflam- matory or infected conditions affecting the lacrimal drai- nage complex. Neurological examination showed decrease of all sensations in the distribution of the three branches of the right trigeminal nerve. Function of the other cranial nerves was intact and there were no motor or sensory defi- cits in the limbs. Routine metabolic workup as well as CSF examination were within normal limits.
