Unusual clinical manifestation of a cerebral infarction restricted to the insulate cortex.

Lesions limited to the insulate cortex can manifest clinically in various forms due to the extensive connections in the area. In this paper, we present a 66-year-old patient who presented to our out-patient clinic with complaints of diminished pleasure in taste and persistent taste of rotten melon. These symptoms were linked to an infarction involving the left anterior insulate cortex. The role of the insular region on cortical processing of taste sensation is discussed, together with a review of the literature on insular infarctions.
