A unique case of concomitant intra and extracranial Hansen's disease.

Leprosy is a debilitating disease that usually involves the peripheral branches of the cranial nerves leading to anesthetic/hypoesthetic skin lesions and thickened peripheral nerves. However, the involvement of the central nervous system (CNS) is extremely rare. To the best of the author's knowledge, the involvement of the cranial nerve nuclei by leprosy has not been reported in the literature and the present case is the first report of involvement of the facial nerve nuclei by leprosy.
