The authors present a rare case of cavernous angioma mimicking a meningioma in a 58-year-old man who presented with a headache and dizziness. There were no neurological deficits or other neurological symptoms or signs. An extra-axial mass lesion thought to be associated with diffusely well-enhanced falx in the postcontrast sections was noted in the posterior interhemispheric fissure near the posterior part of the corpus callosum splenium. Extra-axial cavernous angiomas (cavernomas) are extremely rare lesions. They most commonly occur in the parenchyma but have been occasionally reported to arise from the dura matter. Dural cavernous angiomas arise from dural sinuses, falx cerebri, tentorium cerebelli, cranial base dura, or internal auditory canal dura and convexity. Parenchymal cavernous angiomas classically have a ring of hemosiderin surrounding the lesions observed on magnetic resonance imaging, but dural cavernous angiomas do not display the same magnetic resonance imaging characteristics and occasionally exhibit a dural tail sign due to which they can often be misdiagnosed as meningiomas.
作者报告了一例罕见的海绵状血管瘤病例，该病例发生在一名58岁男性身上，表现为头痛和头晕，影像学表现酷似脑膜瘤。患者无神经功能缺损或其他神经症状及体征。在胼胝体压部后方的大脑镰后间裂处发现一个轴外肿块病变，在增强扫描图像上可见大脑镰弥漫性强化。轴外海绵状血管瘤极为罕见。它们最常发生于脑实质，但偶尔也有报道起源于硬脑膜。硬脑膜海绵状血管瘤起源于硬脑膜窦、大脑镰、小脑幕、颅底硬脑膜、内耳道硬脑膜或凸面硬脑膜。脑实质海绵状血管瘤在磁共振成像上通常表现为病变周围有一圈含铁血黄素环，但硬脑膜海绵状血管瘤不具有相同的磁共振成像特征，偶尔会出现硬脑膜尾征，因此常被误诊为脑膜瘤。
