Overview
History and Symptoms
The clinical presentation of various brain tumors is best appreciated by considering the relationship of signs and symptoms to anatomy. General signs and symptoms include headaches; gastrointestinal symptoms such as nausea, loss of appetite, and vomiting; and changes in personality, mood, mental capacity, and concentration. Whether primary, metastatic, malignant, or benign, brain tumors must be differentiated from other space-occupying lesions such as abscesses, arteriovenous malformations, and infarction, which can have a similar clinical presentation. Other clinical presentations of brain tumors include focal cerebral syndromes such as seizures. Seizures are a presenting symptom in approximately 20% of patients with supratentorial brain tumors and may antedate the clinical diagnosis by months to years in patients with slow-growing tumors. Of all patients with brain tumors, 70% with primary parenchymal tumors and 40% with metastatic brain tumors develop seizures at some time during the clinical course.
