Feil, Katharina; Huber, Marion; Goldschagg, Nicolina and Kellert, Lars (2018): Unilateral Asterixis in Arm and Leg Caused by Internal Capsula Stroke. In: Case Reports in Neurological Medicine, Vol. 2018, 3946380 [PDF, 665kB]

Abstract

We report an unusual clinical manifestation of ischemic stroke with acute right-sided asterixis affecting the arm as well as the leg due to a lesion in the left posterior limb of the internal capsula. After treatment with intravenous thrombolysis the patient made a good recovery. Notably, in this case unilateral asterixis affected the armas well as the leg, resulting in postural and gait instability. In addition, damage in the basal ganglia-thalamo-cortical network, as in our patient, has to be distinguished fromother supratentorial causes of acute asterixis like thalamic or frontal lobe lesions linked to the cerebello-brainstem-thalamo-frontal lobe circuits.
