A 47-year-old man without significant clinical history presented to the emergency room for progressive visual disturbances. On examination, a horizontal diplopia worsening in the left lateral gaze was noted.
47岁男性,既往体健,因渐进性视力障碍就诊。体检左侧注视时水平复视。
Axial T2WI demonstrates a mass lesion isointense to the gray matter in the region of the left cavernous sinus. Contrast-enhanced axial T1WI, obtained sequentially as early as 6 minutes and 15 min following gadolinium enhancement, demonstrate progressive pooling of contrast within the left cavernous sinus lesion. RBC-tagged scintigraphy demonstrates increased uptake in the region of the left cavernous sinus.
横断位T2WI示左侧海绵窦肿块,与大脑灰质呈等信号。
横断位T1WI增强扫描,及6分钟、15分钟延迟扫描示左侧海绵窦病灶渐进性强化。
核素标记RBC闪烁扫描示左侧海绵窦区摄取增加。
Cavernous Sinus Hemangioma
海绵窦血管瘤
Cavernous sinus hemangiomas (CSHs) are uncommon benign lesions. They account for fewer than 1% of parasellar masses, with a ratio F:M = 7:1, and are seen mainly in the fourth decade of life.
海绵窦血管瘤(CSHs)是一种少见的良性肿瘤,约占所有鞍旁肿瘤的不足1%,女性发病率约为男性的7倍,好发于30-40岁。
Symptoms range from headaches and retro-orbital pain to cranial nerve palsies with ophthalmoplegia.
临床症状包括头疼、球后疼痛、颅神经麻痹、眼肌瘫痪等。
CSHs are assessed by MRI, for characterization, location, and relationship with the surrounding structures. The MR image findings are of a well-defined mass with low to isointensity on T1-weighted images, and marked hyperintense signal on T2-weighted images. CSHs show a progressive enhancement with a centripetal fill-in pattern.
MRI能较好反映CSHs的特征性影像学表现、位置、与周围结构的关系。病灶一般表现为边界清楚的肿块,T1WI呈低至等信号,T2WI呈明显高信号,增强扫描病灶呈渐进性强化、逐渐向内填充。
The diagnosis can be confirmed by a labeled red cell blood pool scintigraphy.
