[A case of polymyositis with flaccid paraparesis].

Polymyositis is characterized by inflammatory process in muscles and muscle weakness is the main clinical sign of the disease. We report a case of a 65-years old woman suffering from polymyositis with flaccid paraparesis. Forms of polymyositis where only proximal muscles of lower extremities are involved are very rare, so it may cause diagnostic mistakes. Because of that, it is very important to pay a special attention when making the diagnose of paresis.
