Capillary hemangiomas are benign vascular tumors usually diagnosed in infancy and involving skin and soft tissues. We report a rare case of an adult capillary hemangioma of the left sphenoid sinus extending into the intrasellar and parasellar regions. A 71-year-old woman presented with complaints of headaches and diplopia. Magnetic resonance imaging revealed a T2-hyperintense mass-like lesion involving the left posterior ethmoid and sphenoid sinuses and left cavernous sinus, that had extended into the intrasellar and parasellar regions. Dynamic contrast-enhanced computed tomography revealed enhancing vessel-like structures within the lesion during the arterial phase, which were observed to expand further in the late phase of the examination. This characteristic feature indicated increased vascularity, suggesting the presence of a capillary hemangioma. The patient underwent endoscopic resection via the endonasal transpterygoid approach, and the lesion was diagnosed histopathologically as a capillary hemangioma. To aid diagnosis and clinical management, radiologists should be aware of the imaging findings related to capillary hemangiomas.
毛细血管瘤是一种良性血管肿瘤，通常在婴儿期被诊断出来，累及皮肤和软组织。我们报告了一例罕见的成人左蝶窦毛细血管瘤，该肿瘤延伸至鞍内和鞍旁区域。一名71岁女性因头痛和复视而就诊。磁共振成像显示一个T2高信号的肿块样病变，累及左后筛窦和蝶窦以及左海绵窦，并已延伸至鞍内和鞍旁区域。动态对比增强计算机断层扫描显示病变在动脉期有强化的血管样结构，在检查后期观察到这些结构进一步扩大。这一特征表明血管增多，提示存在毛细血管瘤。患者通过鼻内镜经翼突入路进行了切除，病变经组织病理学诊断为毛细血管瘤。为了辅助诊断和临床管理，放射科医生应了解与毛细血管瘤相关的影像学表现。
