摘要

摘要：一名62岁男性，既往接受口腔癌治疗，出现新发认知运动症状。脑MRI显示脑室周围，右前基底节区和下丘脑有明显增强病变，怀疑为脑肿瘤，特别是中枢神经系统淋巴瘤。18F-FDG脑PET/CT显示相应摄取提示原发性脑肿瘤、淋巴瘤或转移。后续MRI显示增强和肿块效应的分辨率有利于发展中的亚急性梗死。MRI有助于诊断Heubner区复发动脉梗死，Heubner区复发动脉梗死被认为是PET/CT上18F-FDG摄取假阳性的潜在原因，模拟颅内肿瘤。

Subacute Infarction of Recurrent Artery of Heubner Mimicking CNS Tumor With Correlative Brain MRI and 18 F-FDG PET/CT Findings.

Abstract: A 62-year-old man, previously treated for oral cavity carcinoma, presented with new-onset cognitive-motor symptoms. Brain MRI revealed a periventricular, avidly enhancing lesion in the right anterior basal ganglia and hypothalamus suspicious for a brain tumor, particularly CNS lymphoma. 18 F-FDG brain PET/CT showed corresponding uptake suggestive of primary brain tumor, lymphoma, or metastasis. Follow-up MRI showed resolution of enhancement and mass effect favoring an evolving subacute infarct. The diagnosis of an infarct in the recurrent artery of Heubner territory was facilitated by MRI, and recurrent artery of Heubner infarction was noted as a potential cause for false-positive 18 F-FDG uptake on PET/CT, mimicking intracranial tumor.
