BACKGROUND Methanol is a toxic alcohol that is often ingested accidentally or intentionally. Its metabolites can induce severe visual disturbances, metabolic acidosis, and neurological dysfunction, which can frequently become life-threatening. CASE REPORT A 44-year-old woman with a history of depression and alcohol use was hospitalized in the Intensive Care Unit after cardiopulmonary reanimation. According to relatives, an empty bottle of household chemicals was found next to the patient. The patient had symptoms of vomiting, headache, and vision loss. The patient had a hypertensive crisis, with blood pressure of 180/110 mmHg. Initially, on the computed tomography of the head, no conclusive acute changes were detected. However, a slight hypodensity in the basal nuclei was marked retrospectively. On day 4, magnetic resonance imaging of the head was performed, showing symmetrical acute ischemic changes in the basal nuclei with hemorrhage and spreading into the ventricles, and acute occlusive hydrocephalus. Bilateral acute symmetric ischemic changes of both optic nerves with cytotoxic edema were also detected on diffusion-weighted imaging. Dynamically, the condition did not improve, and all vital functions worsened. The patient's lethal outcome was confirmed. CONCLUSIONS Cerebral hemorrhage is a rare and serious complication of methanol poisoning. Early sign detection of methanol intoxication is crucial due to the rapid progression of severe, irreversible complications. Neuroimaging has a significant role in diagnosing and understanding the extent of damage in methanol poisoning cases.
背景 甲醇是一种有毒的醇类,常被意外或故意摄入。其代谢产物可导致严重的视觉障碍、代谢性酸中毒和神经功能障碍,这些情况常常会危及生命。病例报告 一名有抑郁症和饮酒史的44岁女性在心肺复苏后入住重症监护病房。据亲属称,在患者身旁发现了一个空的家用化学品瓶子。患者有呕吐、头痛和视力丧失的症状。患者出现高血压危象,血压为180/110 mmHg。最初,头部计算机断层扫描未发现明确的急性变化。然而,回顾性地发现基底核有轻微低密度影。在第4天,进行了头部磁共振成像,显示基底核有对称性急性缺血性改变并伴有出血,且蔓延至脑室,还有急性梗阻性脑积水。在扩散加权成像上还检测到双侧视神经有急性对称性缺血性改变并伴有细胞毒性水肿。动态观察发现病情没有改善,所有重要功能均恶化。患者最终死亡。结论 脑出血是甲醇中毒罕见而严重的并发症。由于严重的不可逆并发症进展迅速,早期发现甲醇中毒的迹象至关重要。神经影像学在诊断和了解甲醇中毒病例的损伤程度方面具有重要作用。
