Preoperative magnetic resonance imaging with tractography. Lesion in the left temporal parahippocampal gyrus suggestive of cavernoma. Note the proximity of the visual or retinogeniculo-calcarine tract (pink color). The arcuate fascicle is shown in green and the corticospinal tract in blue.

After performing corticotomy in the parahippocampal gyrus with the support of neuronavigation-guided monitoring, the cavernous angioma was located [Figure 2].
Postoperative magnetic resonance imaging T1 weighted with contrast. Surgical cavity in the posterior third of the left temporomesial region with complete resection of the cavernoma.
