Introduction: Sensorial impairment without hemiplegia is usually caused by a thalamic lesion., Case Report: A 28-year-old woman presented with hemianesthesia associated with aphasia following a left insular lesion, subsequent to subarachnoid hemorrhage. Brain MRI Flair sequence revealed a high intensity signal in the left insular and frontal subcortical regions. Insular infarct was diagnosed, associated with hemorrhagic sequelae., Discussion/conclusion: Study of the normal and pathologic insular cortex suggest several implications of the region in somatosensory and language functions. However, the insular cortex has been mainly associated with central pain. Lasting objective hypoesthesia has been very rarely documented. The left insular cortex has also been implicated in speech apraxia but our patient presented with fluent aphasia mostly affecting the rhythm of speech, as it has been observed in thalamic aphasia.

A 64-year-old man with alien hand syndrome presented with abnormal feelings in the left upper limb, associated with an intermanual conflict. There were no clinical signs of frontal or parietal apraxia. This syndrome was induced by an infarct localized in the right posterior area of the splenium, subsequent to a cardiogenic embolus. This observation enlightens the rising syndrome of callosal type alien syndrome due to a posterior callosal infarct.
