BACKGROUND
The most common etiology of classic trigeminal neuralgia (TN) is vascular compression. However, other causes must be considered. Among these, spontaneous hematoma of the Meckel's cave (MC) causing symptomatic TN is very rare.
CASE DESCRIPTION
We present the case of a 60-year-old woman with a 2-month history of left TN and diplopia. Neuroradiological examinations revealed a well-defined hematoma in the left MC. The patient underwent surgical decompression with a progressive neurological improvement.
CONCLUSION
Despite the number of lesions potentially affecting the MC, spontaneous hemorrhage is rare but should be taken into account in the differential diagnosis.
背景
经典三叉神经痛（TN）最常见的病因是血管压迫。然而，必须考虑其他病因。其中，导致症状性TN的Meckel腔（MC）自发性血肿非常罕见。
病例描述
我们报告一例60岁女性，有2个月的左侧TN和复视病史。神经放射学检查显示左侧MC有边界清晰的血肿。患者接受了手术减压，神经功能逐渐改善。
结论
尽管可能影响MC的病变数量众多，但自发性出血很少见，但在鉴别诊断中应予以考虑。
