BACKGROUND
The corpus callosum is the most important pathway enabling the exchange of information between the two cerebral hemispheres. Transient splenium lesions may develop in association with various pathologies and infections. We report a case presenting to the emergency department with transient visual loss and in which a transient lesion was determined in the splenium of the corpus callosum (SCC).
CASE REPORT
A 24-year-old woman presented to the emergency department due to sudden onset visual loss. An area of restricted diffusion was determined in the SCC at diffusion magnetic resonance imaging (MRI) of the brain. The patient was admitted to the ward with a diagnosis of SCC lesion. The lesion had resolved entirely at control MRI performed 2 weeks later.
CONCLUSION
There may be many causes of transient SCC lesions, and patients may present with different clinical manifestations, particularly altered consciousness and rarely visual loss like our present case.
背景
胼胝体是实现两个大脑半球之间信息交换的最重要通路。短暂性压部病变可能与各种病理状况和感染有关。我们报告一例因短暂性视力丧失到急诊科就诊的病例，该病例中胼胝体压部（SCC）发现有短暂性病变。
病例报告
一名24岁女性因突发视力丧失到急诊科就诊。脑部弥散磁共振成像（MRI）显示SCC有弥散受限区域。患者以SCC病变诊断收入病房。两周后复查MRI时病变已完全消退。
结论
短暂性SCC病变可能有多种原因，患者可能表现出不同的临床表现，特别是意识改变，像我们目前这个病例中出现视力丧失的情况则很少见。
