Central pain derived from cerebral tumors is considered rare by most authors. The few cases described in literature refer to central pain caused by expansive lesions in the contralatral parietal cortex. Usually, not even thalamic tumors cause central pain. We describe two cases of central pain related to expansive lesions in the parietal cortical region -- a low grade astrocytoma and a meningioma. Both patients reported pain relief after lesions were removed by surgery.
