Internal Watershed Infarction as an Imaging and Clinical Challenge: a Case Report.

We presented the case of a patient with internal watershed infarction with a nonspecific clinical presentation including hemiplegia, hemisensory deficit, and speech disturbance. Neuroimaging and ultrasound diagnostic procedure are important tools for diagnosis of these rare ischemic events that count for about 6% of all strokes.  Specific therapy is mandatory for the diagnosis of watershed infarction and different from the therapeutical measures than can be taken for embolic and atherothrombotic strokes. Our patient was a 69-year-old, right-handed Caucasian woman who presented to our facility with acute right side weakness and speech disturbance. He had hypothyroidism, permanent atrial fibrillation, diabetes mellitus and she was hypotensive. She reported dizziness few days before the accident. Imaging studies revealed internal watershed infarction. Therapeutic procedures were taken to restore low cerebral blood flow. Internal watershed infarction is rare (less than 10% of all strokes) but well recognized a clinical feature of stroke. Specific pathophysiology generally is connected with hypoperfusion and hemodynamic mechanisms. Specific therapy is mandatory for these conditions.
