Vertebrobasilar Artery Stroke as the Heralding Sign of Systemic Lupus Erythematosus

Cerebral ischemia because of vertebrobasilar insufficiency (VBI) rarely presents as an initial sign within the systemic lupus erythematosus (SLE) population, and there are very few case reports supporting this manifestation. This report details 3 different patients with SLE who experienced VBI as an initial manifestation. Patient 1 was a 24-year-old female who developed a bilateral pontine lesion as a consequence of basilar artery stenosis. Patient 2 was a 34-year-old male with an acute ischemic lesion on the right side of his cerebellum and pons because of significant stenosis in the distal segment of the right vertebral artery. Patient 3 was a 37-year-old female, previously diagnosed with multiple sclerosis, with multiple lesions in her cerebellum and pons bilaterally. Further investigations within this case revealed severe stenosis of the left vertebral artery. The diagnosis of SLE was based on clinical presentations such as myalgia, skin rashes, ulcers, and fatigue along with relevant laboratory findings including positive anti ds-DNA antibody and depressed levels of complement C3 and C4 proteins. In young patients with multifocal ischemic lesions or infarcts in the posterior cerebral circulation system, physicians should investigate for less common etiologies such as SLE.
