‘Man-in-the-barrel’ syndrome: a case report of bilateral arm paresis following cardiac arrest

‘Man-in-the-barrel syndrome’ (MIBS) is a neurological phenotype with brachial diplegia, normal sensation, and preserved motor function of the lower limb. Severe hypotension leading to watershed infarctions leading to this phenotype has been reported. The pathogenesis of MIBS is believed to be cerebral hypoperfusion leading to border zone infarctions between the territories of the anterior and middle cerebral arteries. CASE REPORT AND DISCUSSION: A 49-year-old chronic alcoholic hypertensive Indian male was evaluated for barrel syndrome after a cardiac arrest. MRI confirmed hyperintensities between the territories of the anterior and middle cerebral arteries bilaterally. CONCLUSION: Person in barrel syndrome is a rare neurological syndrome. MIB is common after cerebral hypoperfusion and carries a poor prognosis. Identification of the underlying cause is important because the management and prognosis vary based on the etiology.
