Pseudosubarachnoid Hemorrhage on MRI: A potential pitfall

Fluid attenuated inversion recovery (FLAIR) is one of the most effective magnetic resonance imaging (MRI) sequences in diagnosis subarachnoid hemorrhage (SAH). However, sometimes false positive or negative results can occur. One reasons that lead to erroneous interpretation artifacts. Especially when metallic artifact occurs, hyperintensity may be observed space, similar SAH. Although FLAIR hyperintensities sulci detected many serious diseases, they are not always pathological. Artifact related hyperintensities, especially cases with severe headache, mistakenly evaluated as SAH by a clinician radiologist who well-experienced MRI. it extremely important recognise these make correct and prevent unnecessary interventions. In order achieve this, evaluation all radiological images, SWI GRE, critical. Both radiologists clinicians evaluating neuroradiological examinations should knowledgeable about this subject show maximum attention.
