title: [Diagnostic challenges of aneurysmal subarachnoid hemorrhage].
abstract: Diagostic approach to aneurysmal subarachnoid hemorrhage (aSAH) is based on computer tomography (CT) imaging, although a lumbar puncture and subsequent cerebrospinal fluid analysis is sometimes necessary. Identification of the ruptured aneurysm is done using angiography. Despite of modern imaging techniques, diagnostic definition of aSAH is still occasionally challenging. We describe three cases in which the diagnosis of aSAH has been delayed, in spite of positive imaging or lumbar puncture findings.
