Abstract:
Diaphragm dysfunction can originate from various etiologies, and bilaterality of the dysfunction depends on the cause. Symptoms of diaphragm dysfunction vary depending on the degree of phrenic nerve denervation, spinal cord lesion, and involvement of the diaphragm. Several infectious diaphragmatic dysfunctions have been reported, including the human immunodeficiency virus, poliovirus, West Nile virus, and dengue virus. Here, we report a case of unilateral diaphragm paralysis in a 34-year-old man with neurosyphilis.
