New type of lacunar stroke presenting in brain perfusion images: A case report

BACKGROUND A stroke is a significant brain event that impinges on individual motor or cognitive functions. In the lacunar stroke subtype of ischemic stroke, which results from blocked blood flow in certain brain areas, cases of dysarthria due to impaired blood flow are not uncommon. However, limited literature and research on the relevant pathophysiology and neural pathways exist. CASE SUMMARY We focus on a 60-year-old female with subacute stroke presenting symptoms including tongue deviation to the right, speech difficulty, choking on water, and biting the oral mucosa. She did not exhibit abnormalities in limb movement or sensation except for numbness in the tongue. We use single-photon emission computed tomography to reveal reduced blood flow in the left parietal lobe and bilateral temporal lobes. This report presents an atypical case of dysarthria, who exhibits abnormal articulation along with abnormal sensation and numbness in the tongue, prompting further investigation into the association between lacunar stroke subtypes, altered blood perfusion in affected brain regions, and neurological clinical status. CONCLUSION Dysarthria-plus syndrome in lacunar stroke isn’t solely related to motor function but also affects sensory function such as oral numbness.
