Abstract
PURPOSE: The features of intracranial arterial injury in tuberculous meningitis (TBM) are of important diagnostic and prognostic value. The study aimed to elucidate the high-resolution vessel wall imaging (HR-VWI) manifestations of intracranial arterial insults in TBM. METHODS: The clinical data, routine cranial magnetic resonance imaging, magnetic resonance angiography (MRA) and HR-VWI before and after contrast enhancement of intracranial arteries in clinically diagnosed TBM patients were retrospectively analyzed. RESULTS: In this study 27 TBM patients were included. Abnormalities in the intracranial arteries were detected in all patients using HR-VWI. Typical vessel insults included nodular or granular lesions, related thickness and prominent enhancement in the wall, and lumen narrowing or occlusion. The most frequently involved arteries were the C4 segment of the internal carotid artery and the P1 segment of the posterior cerebral artery. The lesions were consistent with disease stage and disease duration and correlated with infarction. CONCLUSION: The use of HR-VWI revealed that cerebral artery involvement in patients with TBM is much more common and extensive than in previous radiological reports. The use of HR-VWI improves recognition of arterial pathologies and has diagnostic value in patients with TBM.
