Dural hemangiomas are a relatively rare form of intracranial mass, as hemangiomas tend to present in bone or as intraparenchymal lesions and only around 5%-13% have been reported to originate from the dura mater. Here, the authors present the case of a 46-year-old female who underwent craniotomy for a suspected convexity meningioma resection, which was unexpectedly found to be a dural capillary hemangioma.
The patient was a 46-year-old female who presented with a left frontal intracranial mass found incidentally and showed significant growth over 4 years. The mass was suspected to be a meningioma as it was homogeneously enhancing, extra-axial, and exhibited findings of a broad base with a dural tail along the dura of the superior frontal lobe. This was excised en bloc and found to be a purplish-red mass firmly attached to the dura, which was diagnosed as a capillary hemangioma on histopathology.
Dural hemangiomas, particularly at the convexity, are quite rare and can mimic meningiomas on imaging, sometimes even demonstrating homogeneous enhancement with a broad base and dural tail. These are an important part of the differential diagnosis when diagnosing dural-based masses and should be considered when planning operative or radiation treatment. https://thejns.org/doi/10.3171/CASE24476.
硬脑膜血管瘤是一种相对罕见的颅内肿块形式，因为血管瘤往往出现在骨骼中或表现为脑实质内病变，据报道只有约5%-13%起源于硬脑膜。在此，作者报告一例46岁女性病例，该患者因疑似凸面脑膜瘤切除术接受开颅手术，结果意外发现是硬脑膜毛细血管瘤。
该患者为46岁女性，偶然发现左额叶颅内肿块，4年间有显著生长。该肿块被怀疑为脑膜瘤，因为它呈均匀强化，位于轴外，表现为宽基底并沿额上叶硬脑膜有硬脑膜尾征。该肿块被整块切除，发现是一个紫红色肿块，牢固附着于硬脑膜，组织病理学诊断为毛细血管瘤。
硬脑膜血管瘤，尤其是在凸面，非常罕见，在影像学上可类似脑膜瘤，有时甚至表现为宽基底和硬脑膜尾征的均匀强化。在诊断硬脑膜肿块时，这些是鉴别诊断的重要部分，在计划手术或放射治疗时应予以考虑。https://thejns.org/doi/10.3171/CASE24476。
