To the editor:In January 2013,a 58-year-old man presented to our department with an 11-month history of intermittent fever.He experienced recurrent low-grade fever and a non-productive cough without hemoptysis since February 2012.A chest CT showed diffuse ground-glass opacity and consolidation in both lungs.At that time,he was diagnosed as pneumonia and prescribed azithromycin and ciprofloxacin at a local hospital.The symptoms recurred after discontinuation of the antibiotics.He reported weakness of dominant muscles of his left leg in December 2012.Subsequently,loss of pain and temperature sensation was noted in his right leg,following a painless scalding,and he denied incontinence.Neurological examination revealed paraparesis below the T8 spinal cord segment.Muscle strength in the left and right legs was 0/5 and 4+/5,respectively.Deficits in pain and thermal sensations were detected in the right leg,while deep sensations were spared.Patellar and calcaneal tendon reflexes were brisk,and Babinski reflex was positive on both sides.
