Headache related to brain tumors.

Headache is one of the most common somatic complaints of patients seeking medical care. Most headaches are not of serious cause and can be diagnosed easily with a good history and physical examination. The challenges to the physician are to determine when underlying intracranial pathology may be causing the symptoms and signs, and to identify the few patients in whom a tumor is the cause of the headache. The subject of headache in patients with brain tumors has been reviewed in neurologic textbooks and in several investigations before, as well as after, modern imaging diagnostic techniques became available. Headache can also manifest as an acute or chronic complication of radiation treatment and/or chemotherapy in patients with intracranial neoplasm, but there are few data in the literature specifically addressing this subject. This article provides an overview of headache in patients with primary and secondary brain tumor, including headache characteristics, the putative mechanism for these headaches, the role of diagnostic testing, and the general principles of management.
