The lesions were registered to Montreal Neurological Institute standard anatomical space, and heat\u2010map and 3\u2010dimensional rendered frequency images were generated. All tumors were then superimposed on the Anatomical Automatic Labeling (AAL) template to further investigate the difference in the tumor location based on the voxel\u2010wise frequency of occurrence with respect to laterality, sex, age, and pathologic grade.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The 3\u2010dimensional rendered images show that the tumors commonly located in the posterior cranial cavity, surrounding the tentorium. The posterior third of the superior sagittal sinus and the confluence of sinuses were commonly affected. According to the analysis of tumor occurrence frequency in the AAL template, IHPCs were mainly observed in the limbic lobe, occipital lobe, and cerebellum. Tumors in younger patients preferentially located in the right occipital region (<jats:italic>P<\/jats:italic> = .027), whereas those with higher pathological grade more often located in the left parietal lobe (<jats:italic>P<\/jats:italic> = .034).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>This is the first voxel\u2010based study to explore the predilection site of IHPCs. Our study suggests that these tumors commonly affect the posterior cranial cavity, adjoining the tentorium and venous sinus.
