Occasionally, large benign intracranial tumours which have existed for many years present as a relatively acute problem. The mechanisms underlying the sudden change are sometimes unclear but infarction of the benign tumour, subsequent cerebral oedema and an increase in intracranial pressure have been reported. The authors describe such a case of focal infarction in a meningioma with a precise chronology of the clinical, radiological and pathologic findings.
偶尔，已存在多年的大型颅内良性肿瘤会表现为相对急性的问题。这种突然变化的潜在机制有时尚不清楚，但已有报道称良性肿瘤发生梗死、随后出现脑水肿以及颅内压升高。作者描述了这样一例脑膜瘤局灶性梗死病例，详细记录了临床、放射学和病理学发现的时间顺序。
