Transient left-sided alien hand with callosal and unilateral fronto-mesial damage: a case study.
A patient who showed a transient left alien hand after a subarachnoid haemorrhage, due to a ruptured aneurysm of the anterior communicating artery, is described. No left agraphia and left apraxia could be found. A CT-scan including coronal sections showed a right medial frontal hypodensity and different ischaemic lesions in the anterior part of the corpus callosum. The possible anatomic site of the lesion responsible for the permanent form of alien hand is discussed.
