Introduction This article aims to describe a patient with Parinaud syndrome due to neurotuberculosis confirmed by cerebrospinal fluid analysis. Case Report Initially, patient sought medical care, performed a chest x-ray and later a chest CT scan, with a probable diagnosis of miliary tuberculosis. In addition, she presented binocular diplopia worse at right lateral gaze, paresis of vertical gaze, light near-dissociation and convergent retraction nystagmus and presence of mycobacterium tuberculosis on PCR Xpert MTB/RIF. The treatment of miliary tuberculosis was interrupted due to pharmacodermia, but after diagnosis of neurotuberculosis, it was restarted with isoniazid, pyrazinamide and ethambutol with partial visual symptoms improvement. Discussion This case demonstrates the importance of pursuing diagnosis through more accurate techniques, especially in a patient with previous treatment pharmacoderma, whose absence of proper diagnosis and treatment would be extremely deleterious.
