Parinaud syndrome due to cofirmed neurotuberculosis in a lupus eritematosis systemic patient.

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.
