“…On the other hand, DSA has several shortcomings, including invasiveness due to the arterial puncture and intra-arterial catheter procedure, the need for expert proficiency with the procedure, and its comparatively high expense [ 19 ]. Regarding infectious intracranial aneurysm, some authors have already concluded that MRI is useful for diagnosing microaneurysms that have developed in the peripheral vasculature [ 20 – 23 ]. Cho et al point out that suggestive MRI findings can offer a sensitive and specific tool for identifying infectious intracranial aneurysm [ 24 ].…”

Delayed Tentorial Subdural Hematoma Caused by Traumatic Posterior Cerebral Artery Aneurysm: A Case Report and Literature Review

Patient: Male, 42-year-old Final Diagnosis: Traumatic posterior cerebral artery aneurysm Symptoms: Deterioration of mental status and disorientation Medication: — Clinical Procedure: Parent artery occlusion by endovascular approach Specialty: Neurosurgery Objective: Unusual clinical course Background: Subdural hematoma (SDH) caused by traumatic intracranial aneurysm (TICA) is rare. TICAs are known to rupture easily, resulting in a high morbidity and mortality rate. Therefore, accurate diagnosis and treatment are crucial for preserving life. We describe a case of delayed SDH in the setting of posterior cerebral artery (PCA) aneurysm. Case Report: A 42-year-old man presented with sustained head injury from a traffic accident, and was being followed-up conservatively for traumatic SDH and subarachnoid hemorrhage. Three weeks after the head trauma, the patient developed a sudden deterioration of mental status and disorientation. Computed tomography revealed de novo SDH at the cerebellar tentorium. Computed tomography angiography and magnetic resonance imaging demonstrated TICA in the PCA. The patient was diagnosed with SDH due to a ruptured PCA aneurysm at the quadrigeminal segment. To avoid SDH growth due to re-rupture of the aneurysm, parent artery occlusion was subsequently performed with no complications. The patient was discharged home 2 months after endovascular treatment, with moderate disability. Follow-up angiography 2 years after the operation showed no recanalization, and the patient had returned to work. Conclusions: TICA in the PCA can cause tentorial SDH with or without the presence of subarachnoid hemorrhage. Routine cerebrovascular assessment is crucial for head trauma with hematoma adjacent to the cerebellar tentorium. Parent artery occlusion via an endovascular procedure is an alternative treatment for TICA in the PCA that is less invasive than other approaches.

“…45 Recently, parenchymal T2 hypointensities have been found to be associated with infective endocarditis, and could play a role in early diagnosis of this serious condition. 46 CTA risk stratification of TIA/minor stroke for ED triage Fifty to 80% of all ischemic stroke can be classified as minor ischemic stroke, 47 precluding these individuals from acute intervention with intravenous tissue plasminogen activator (tPA) or mechanical thrombectomy. However, those with minor stroke or motor/ speech TIA are at high risk of subsequent disabling stroke and therefore should not be thought of as benign occurrences.…”

Stroke is a major cause of morbidity and mortality worldwide, and effective treatment requires rapid diagnosis and recognition of relevant vascular lesions. In this review we will discuss the usefulness and versatility of computed tomography angiography in the setting of stroke, be it ischemic or hemorrhagic, minor or disabling. Furthermore, we also highlight how we use computed tomography angiography in decision making in transient ischemic attacks, acute disabling ischemic stroke, and hemorrhagic stroke.
