Recently, solitary fibrous tumors (SFTs) have been reported in the head and neck area, such as the nasal cavity, thyroid, salivary gland, etc. We present a rare case of SFT which arose from the sphenoethmoidal recess of the nasal cavity, penetrating into the sphenoid sinus, and which showed different intensities on magnetic resonance imaging (MRI) according to the occupied locations. T2 weighted magnetic resonance (MR) images showed low intensity in the nasal cavity, and iso-intensity in the sphenoid sinus. Enhancement with gadolinium contrast on T1-weighted images was more remarkable in the sphenoid sinus than in the nasal cavity. While the tumor in the nasal cavity showed abundant collagen and high cellularity in microscopic examination, numerous small vessels and dilated vascular spaces were remarkable in the tumor of the sphenoid sinus. MRI findings corresponded to pathological findings. We review SFTs in the head and neck area in the English literature.
最近，头颈部区域已报告有孤立性纤维瘤（SFTs），如鼻腔、甲状腺、唾液腺等部位。我们报告了一例罕见的鼻腔蝶筛隐窝起源的SFT，该肿瘤侵入蝶窦，在磁共振成像（MRI）上根据占据部位显示出不同强度。T2加权磁共振（MR）图像显示鼻腔内为低强度信号，蝶窦内为等强度信号。T1加权图像上钆对比剂增强在蝶窦比鼻腔更显著。显微镜检查显示鼻腔内肿瘤富含胶原且细胞密度高，而蝶窦内肿瘤有许多小血管和扩张的血管间隙较为显著。MRI表现与病理结果相符。我们回顾了英文文献中头颈部区域的SFTs。
