| Abstract | Context: Given its cerebral amyloid angiopathy, subarachnoid hemorrhage might represent transient focal neurological episodes erroneously diagnosed as transient ischemic attacks. The earliest neuroimaging findings in emergency room brain computed tomography indicating subarachnoid hemorrhage in these patients might be very subtle and missed by the clinician. Case Presentation: An 80-year-old man referred with transient focal neurological episodes, suggestive of transient ischemic attacks. In general, except for some cognitive dysfunctions, no remarkable point was noticed in his neurological examination. Non-enhanced brain-computer tomography and magnetic resonance imaging revealed evidence indicating slight convexity subarachnoid hemorrhage at the left frontal cortical region. Conclusions: The transient focal neurological episodes uncommonly represent intracranial hemorrhage. Nevertheless, this clinical representation might occur in patients with subarachnoid hemorrhage due to cerebral amyloid angiopathy. In such cases, the neuroimaging findings play a major role in the differential diagnosis. The misdiagnosis of transient ischemic attacks in these cases might lead to the consumption of antiplatelet drugs and end in catastrophic hemorrhage and life-threatening complications. Close attention to patients' clinical findings and judicious use of further neuroimaging studies would help clinicians to avoid making such mistakes. | en |
