Abstract: Objective To evaluate the alternations of degree centrality (DC) in the brain of a patient with alternating Horner’ssyndrome (AHS). Methods Conventional magnetic resonance imaging (MRI), 3D structure reconstruction and resting-statefunctional MRI were performed in a patient with AHS and 8 healthy adults. The DC of brain functional connectivity wascalculated and statistically analyzed to evaluate the changes in the nodes in the brain default network of the patient. Results Inthe AHS patient, the DC at onset of left eye involvement was located mainly in the bilateral anterior middle frontal gyri, frontaloperculum and opercula insulae; the brain regions with a DC greater than the mean DC of the whole brain were found mainlyin the bilateral occipital lobes, temporal lobes and cingulate gyri, and the brain regions with a significantly decreased DCincluded mainly the left inferior temporal gyrus, postcentral gyrus, right superior temporal gyrus, lateral occipital gyri andbilateral paracentral lobules (P<0.05). At the onset of right eye involvement, the DC was mainly located in the anterior part ofthe bilateral superior and middle frontal gyri, parietal lobes, middle cingulate gyri and medial occipital gyri; the brain regionswith a DC greater than the mean DC of the whole brain included the bilateral occipital lobers, temporal lobes, cigulate, orbitalgyri and gyrus rectus, and the brain regions with a significantly decreased DC included the left supramarginal gyrus, rightlateral occipital gyrus, paracentral lobule and bilateral superior temporal gyrus. Conclusion The AHS patient exhibited adecreased DC of functional connectivity in multiple brain regions.
