Tuberculoma presenting as isolated sixth nerve palsy: A rare case report

Tuberculomas constitute 5-30% of the space occupying lesions of central nervous system in developing countries. Children and young adults constitute the most affected population. Most common presentations of tuberculomas are cranial nerve palsies or focal neurological signs but presentation as isolated sixth nerve palsy is very rare. We report a case of an elderly female who presented with history of double vision for 2 months and was found to have isolated abducens nerve palsy of left eye due to tuberculoma in the ponto-medullary junction. Patient improved symptomatically within antitubercular treatment with complete recovery of eye movements.
