The “Man-in-the-barrel syndrome” (MBS) makes reference to a picture of bilateral brachial muscular weakness, of proximal predominance, that incapacitates the patients in the execution of functional activities related with the elevation of the upper limbs. Since its description, there are several cases described of patients with this syndrome, whose etiology differs from the first one described. The most frequent causes of MBS are cerebral vascular disorders, the cardiac and extracardiac surgeries with demonstration of arterial hypotension, cerebral metastases, pons and spinal cord involvement. Bilateral brachial paralysis also can cause similar picture. Thus, the pathophysiologic substratum that becomes related it MBS, in some cases, is uncertain and deserves attention.
