眼窩淋巴管瘤－病例報告
Orbital Lymphangioma-A Case Report with Magnetic Resonance Imaging
摘要
眼窩淋巴管瘤是一種具有容易反覆出血傾向，相對少見的血管性腫瘤，向於它的多囊狀多血管內部結構，以及富含出血之特性，使得核磁共振顯影及核磁共振血管攝影對其而言是一種相當具有鑑別診斷能力的有力工具。 我們報告此一忠有左眼急性凸出，眼肌麻痺以及視神經病變的病例，於核磁共振顯影顯示左眼球後方有一富含血管及出血之腫瘤，同時核磁共振血管攝影亦顯示此腫瘤之流入血管，與臨床上之表現不謀而合，在在支持眼窩淋巴管瘤之特性，因此可以肯定核磁共振顯影以及核磁共振血管攝影對於眼窩淋巴管瘤的診斷上具有很高的價值。

Orbital lymphangioma is a relatively uncommon vascular tumor with a tendency to recurrent bleeding. Conservative exminations of orbital structure, such as echo, computer tomography, have their limitation. Due to its internal structure of multiple cystic spaces, highly vascular contents and bleeding tendency, orbital lymphangioma is perfectly suited for magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA). We presented a series of imaging studies of a 42-year-old male patient who suffered from acute proptosis of left eye with total ophthalmoplegia and optic neuropathy. MRI and MRA demomstrated a highly vascular retrobulbar mass with redent hemorrhage and with a feeding vessel, correlating well to a diagnosis of lymphagioma. We therefore emphasize the benefits of MRI and MRA in the differential diagnosis of orbital tumors.
