Multiple cranial nerve palsies in an elderly diabetic

A 60-year-old man presented with multiple cranial nerve palsies on the right side. He was initiated on anti-tubercular treatment in view of lymphocytic pleocytosis on the cerebrospinal fluid study. Although he improved initially, later he worsened with cranial nerve involvement on the contralateral side. A diagnostic procedure was done, and the team reached a definitive diagnosis and patient responded to the targeted therapy.
