Clinical examination of brachial and pelvic plexus tumors

Abstract

✓A thorough history and physical examination are fundamental to the assessment of patients with brachial and pelvic plexus tumors. Typical of most peripheral nerve tumors, the presenting symptoms and signs are few, and if present, can be subtle. Presenting complaints may include a palpable mass lesion, either symptomatic or asymptomatic; sensory alterations; pain; motor deficits; visceral symptoms; or autonomic dysfunction. Motor deficits are usually a late feature in the pathogenesis of this lesion, and a progressive course of pain and significant sensory and motor deficits suggests a malignant pathological process. A detailed family history may reveal familial syndromes and neurocutaneous disorders that predispose the patient to neoplasia, such as neurofibromatosis. The physical examination should be conducted in a systematic fashion, looking for any cutaneous features and motor and sensory deficits. The mass should also be examined for form, consistency, and mobility. An irregular, firm, and immobile mass suggests a malignant lesion. Complete and accurate clinical information must be gathered to pinpoint the anatomical localization of the lesion and formulate a differential diagnosis.
