title: [Spontaneous intracranial hypotension].
abstract: The authors consider some clinical and radiological aspects of spontaneous intracranial hypotension syndrome, based on the knowledge obtained from three clinical situations. Postural headache was a constant complaint. In all cases, magnetic resonance imaging data obtained was diffuse dural enhancement and, in two cases, bilateral subdural fluid collections. The increasing recognition of this syndrome led to its distinction from meningeal inflammatory or neoplasic conditions, sparing the patient from unnecessary investigation.
