Abstract

Absolute pitch (AP) is known as the ability to recognize and label the pitch chroma of a given tone without external reference. The neural mechanism and its asymmetry of AP musicians remain unclear. We herein report a 41-year-old AP musician who developed a right putaminal hemorrhage. On a postoperative day 5, a fluid-attenuated inversion recovery image revealed the rest of the hematoma and edematous lesion at the right white matter between the Heschl's gyrus and other cortices. Diffusion tensor tractography with the region of interest at the Heschl's gyrus was performed. In the left hemisphere, the anterior part of the arcuate fiber and middle longitudinal fasciculus were observed. However, these connections were absent in the right hemisphere, but her AP ability was maintained. Our case suggested that the fibers from the right Heschl's gyrus to the right frontal lobe via the right ventral stream is not associated with AP.
