Polymyositis.

In a five-month-old girl, who for a week had cried and displayed a relapse in the motor development, generalised hypotonia and meningism were found. Eventually, the results of the cerebrospinal fluid analysis and electromyography indicated Guillain-Barré syndrome. She was treated with immunoglobulins and made a quick recovery. Guillain-Barré syndrome is an acute or subacute inflammatory demyelinating polyradiculoneuropathy that can occur at any age. In children, the classic symptoms such as a flaccid paralysis and areflexia are not always predominant. Instead, pain is often the most prominent symptom, along with meningism. These symptoms are often insufficiently recognised in practice and as a result of this, delays in the diagnosis of this potentially life-threatening disease often occur.
