AbstractWe present the case of a healthy young woman who consulted for left peripheral facial palsy associated with fever, dry cough, dyspnea, and asthenia of two weeks' evolution. Physical examination revealed hypoesthesia in left T6 to T12 dermatomes and bilateral galactorrhea. In the laboratory, she presented negative viral serology, elevated erythrocyte sedimentation rate, antinuclear antibody titers, prolactin and thyroid-stimulating hormone, with positive antiperoxidase antibodies. Computed tomography showed multiple bilateral cervical, mediastinal, and hilar adenopathies, without involvement of lung parenchyma. Cerebrospinal fluid culture was negative for common germs, mycobacteria, and Xpert MTB/RIF, and cytology did not show atypia. Contrast-enhanced magnetic resonance was performed on the brain without pathological findings and on the spine with alteration of the centromedullary signal from T6 to T9 of almost the entire thickness of the cord, with posterior enhancement with gadolinium. During hospitalization, she recovered sensitivity in the left trunk and did not repeat febrile or cough episodes. She was referred to another center for mediastinoscopy with lymph node biopsy revealing the presence of numerous non-caseating granulomas compatible with sarcoidosis. It was classified as probable neurosarcoidosis and started treatment with corticosteroids with improvement of the remaining neurological symptoms. A magnetic resonance was performed three months later where the signal alteration was limited from T7 to T8. Our objective is to highlight the florid neurological presentation that made it necessary to rule out other more frequent entities and the favorable evolution even before starting a first-line scheme of treatment.
