Hand knob sign in Wernicke’s encephalopathy

Authors: Akiyuki Hiraga, Satoshi Kuwabara

Excerpt

The hand knob is an inverted omega-shaped hand motor area in the precentral gyrus. Numerous previous studies have shown that cortical infarcts located in the hand knob can present as isolated hand/finger palsy [1]. However, the relevance of the hand knob in other disorders is largely unknown. Here, we report a case of Wernicke’s encephalopathy (WE) with a bilateral “hand knob sign” on magnetic resonance imaging (MRI). …
