Article Description

The subcallosal area is important for higher brain functions such as emotion and memory. This area is connected to the cingulate fasciculus from the cingulate gyrus and the uncinate fasciculus from the medial temporal lobe. We experienced a case of subcallosal glioblastoma (GBM) with postoperative depression and hemiplegia that had a clinical course resembling that of supplementary motor area (SMA) syndrome. SMA syndrome is related not only to the SMA but also to the cingulate fasciculus and other white matter fibers. Removing subcallosal GBM may interrupt the input of emotional signals from the temporal lobe via the uncinate fasciculus and output signals to the SMA via the cingulate fasciculus. Furthermore, the interruption of these signals may cause depression and SMA syndrome. This case report provides suggestions for discussing the function and fiber connections of the subcallosal area.
