STUDY DESIGN
A case of cyclic sciatica secondary to ovarian cyst endometriosis is presented.
OBJECTIVES
To report the clinical description and magnetic resonance imaging aspects of cyclic sciatica.
SUMMARY OF BACKGROUND DATA
Endometriosis of the sciatic nerve is rare, but must be included in the differential diagnosis of sciatic mononeuropathies.
METHODS
The authors report a new case of a woman whose cyclic sciatica was caused by an ovarian cystic endometriosis lesion.
RESULTS
Magnetic resonance imaging was described as hyper- and hypointense on T1-weighted sequences, and hyperintense on T2-weighted sequences at the sciatic notch.
CONCLUSION
Magnetic resonance imaging may permit a specific diagnosis of this unusual cause of sciatica by showing a hemorrhagic mass in the region of the sciatic nerve. Early recognition is necessary to prevent permanent damage to the sciatic nerve.
研究设计
报告一例继发于卵巢囊肿型子宫内膜异位症的周期性坐骨神经痛病例。
目的
报告周期性坐骨神经痛的临床描述及磁共振成像表现。
背景资料总结
坐骨神经子宫内膜异位症罕见，但坐骨单神经病的鉴别诊断中必须考虑到该病。
方法
作者报告一例女性患者，其周期性坐骨神经痛由卵巢囊肿型子宫内膜异位症病变所致。
结果
磁共振成像显示，在坐骨切迹处，T1加权序列呈高信号和低信号，T2加权序列呈高信号。
结论
磁共振成像通过显示坐骨神经区域的出血性肿块，可能对这种不常见的坐骨神经痛病因作出特异性诊断。早期识别对于防止坐骨神经永久性损伤很有必要。
