Neuralgic Amyotrophy Manifesting as Mimicking Posterior Interosseous Nerve Palsy
نویسندگان
چکیده
The upper trunk of the brachial plexus is the most common area affected by neuralgic amyotrophy (NA), and paresis of the shoulder girdle muscle is the most prevalent manifestation. Posterior interosseous nerve palsy is a rare presentation in patients with NA. It results in dropped finger on the affected side and may be misdiagnosed as entrapment syndrome or compressive neuropathy. We report an unusual case of NA manifested as PIN palsy and suggest that knowledge of clinical NA phenotypes is crucial for early diagnosis of peripheral nerve palsies.

Palsy of the anterior interosseous nerve (AIN) was first described by Tinel1 in 1918 under the title ‘Dissociated paralysis of the median nerve’. In 1948 Parsonage and Turner2 noted six examples of this syndrome in a review of 136 patients with neuralgic amyot...

solated palsy of the posterior interosseous nerve (PIN) can occur without nerve compression and is often referred to as isolated neuritis or neuralgic amyotrophy because of its characteristic elbow pain at the onset, lasting days to weeks with subsequent weakness. The diagnosis is based on the clinical course because, to our knowledge, there have been no objective tests, in particular imaging f...

متن کاملNeuralgic amyotrophy with bilateral diaphragmatic palsy.
Neuralgic amyotrophy is a well recognised condition of unknown aetiology with characteristic clinical features.' These include severe pain in the shoulder region, followed within hours or weeks by motor or sensory abnormalities, or both, in the distribution of the cervical roots or nerves. Unilateral disease is more common clinically but if electromyographic (EMG) studies are performed bilatera...
متن کامل[Clinical features and MRI characteristics in neuralgic amyotrophy].
Neuralgic amyotrophy (NA) is a distinct peripheral nervous system (PNS) disorder characterised by sudden attacks of neuropathic pain, usually in a unilateral upper extremity, and patchy paresis with amyotrophy. Under-recognition of NA patients may be frequent because symptoms of NA can be similar to those of common orthopedic disorders. The lesion sites of NA are commonly considered to be brach...
