Case Reports

Abstract

We describe two patients in whom CT brain scans imaged paramedian thalamosubthalamic infarcts in the territory of the thalamo-mesencephalic arteries. Such infarcts give rise to a complex syndrome marked by disturbances of consciousness and of eye movement and neuropsychological disorders, including attentional, memory and, more rarely, language deficits. A loss of voice volume may accompany aphasic disturbances but is exceedingly rare in isolation. In the cases described the aphonia, total but transient, was the only language disorder. The physiopathological mechanisms involved in aphonia are complex and controversial.

Sommario

Gli autori descrivono due pazienti in cui la TAC cranica mostra la presenza di infarti talamo-subtalamici paramediani nel territorio di distribuzione delle arterie perforanti talamo-mesencefaliche.

La conseguenza di tali infarti è una complessa sindrome caratterizzata da disturbi di coscienza, della motilità oculare e neuropsicologici tra cui alterazioni del'attenzione, della memoria e più raramente del linguaggio. Un disturbo del volume di voce si può associare ai deficit afasici ma è assai raro come manifestazione isolata.

Gli autori dopo aver descritto due casi di questa sindrome, in cui l'unica anomalia del linguaggio era costituita da afonia, ne discutono i possibili meccanismi fisiopatologici.
