Monochorea and Somatotopic Localization

Chorea and Bacterial Endocarditis

“…The commonest site is the corpus striatum. Lesions here have been associated with contralateral hemichorea in degenerative brain disease (Grunthal and Hartmann, 1940) and embolic disease (Davison and Goodhart, 1940). This discovery of a local lesion is rare and the pathological changes usually comprise generalized oedema with enlargement of the perivascular spaces and perivascular haemorrhages.…”

Effects of Lesions in the Putamen on Involuntary Movements and Rigidity in Parkinson's Disease

“…His patient was a chronic alcoholic with tremor involving the hands, arms, lips and tongue; at necropsy there was necrosis of the medial part of the anterior half of the putamen. Similarly, in Davison and Goodhart's (4) case of monochorea limited to the right upper extremity, there was a partial lesion of the putamen and caudate anteriorally at autopsy. These authors also postulated that there was somatotopic localization in the striatum, the extreme oral pole being associated with the muscles of the head and face, the middle part with the muscles of the upper extremity and trunk, and the caudal part with the muscles of the lower extremity.…”

“…Necropsy revealed symmetrical necrosis of the anterior half of the putamen bilaterally. Davison and Goodhart (4) reported the case of a 41‐year‐old woman with monochorea limited to the right upper extremity. Autopsy revealed a partial lesion of the left putamen and caudate nucleus.…”

Hypertensive putaminal hemorrhage presenting with hemichorea.

“…Hemichorea has occurred secondary to infarcts in the caudate nucleus and putamen. [1][2][3][4] Although the putamen is the commonest site of primary intracerebral hemorrhage, 5 hemichorea was not included in the broad spectrum of clinical presentations seen in one review of 24 cases of putaminal hemorrhage diagnosed by CT scan. 6 Our report describes a patient in whom hemichorea was the major sign of an acute hypertensive putaminal hemorrhage (HPH).…”
