SYMPTOMATIC MIGRAINE - INTRACRANIAL LESIONS MIMICKING MIGRAINOUS HEADACHE - A REPORT OF 3 CASES

Case reports of three headache patients, two with intracerebral meningioma and one with hydrocephalus are presented, in whom the clinical picture fulfilled the criteria of the International Headache Society (IHS) for the diagnosis of migraine. The symptomatic (ie, lesional) nature of the headaches could be detected by neither clinical neurological examination nor routine investigations such as EEG and skull x-ray. On the other hand, brain imaging techniques (CT, MRI) were found to be of particular in value diagnosing the lesions. Our cases indicate that neuroimaging with CT or MRI in the assessment of headache patients should not be handled too restrictively. Compared to CT, however, the additional diagnostic value of MRI in headache seems to be limited.
