Mononeuropathy multiplex and chylothorax as earlier manifestations of pulmonary tuberculosis.

Mononeuropathy multiplex (MNM) and chylothorax are rare clinical disorders. The concurrence of these two disorders with Mycobacterium tuberculosis infection has not been reported. We herein report a patient who was initially diagnosed with fever of unknown origin and MNM, and then developed chylothorax. Pulmonary tuberculosis was proved 1 month after chylothorax appeared. With low-dose prednisolone 15 mg day(-1) and anti-tuberculosis drugs, all these disorders completely resolved 1 year later.
