Résumé
The parietal lobe is often considered a safe entry point for cortical and subcortical tumors because it avoids the somatosensory cortex anteriorly and the visual cortex posteriorly. However, there are a variety of parietal lobe symptoms that can develop from accessing lesions in this region, which include Gerstmann syndrome (right-left confusion, agraphia, and acalculia), aphasia, and agnosia in the dominant hemisphere, as well as constructional apraxia, dressing apraxia, and anosognosia in the nondominant hemisphere. In this chapter, we present a case of a nondominant-hemisphere, parieto-occipital, low-grade glioma.
