Intracranial haemorrhage after supra-tentorial craniotomies can occur in a typical pattern and location which may suggest the diagnosis of remote cerebellar haemorrhage (RCH) which is quite a rare occurrence. The 'Zebra Sign' refers to a pattern of hyperdensity indicative of blood and hypodensity indicative of normal cerebellar parenchyma in a curvilinear, stripe-like fashion along the cerebellar folia and is a characteristic imaging finding in RCH. RCH in general doesn't require surgical treatment, however in cases of significant hydrocephalus or progressive deterioration of consciousness surgical treatment may be warranted. The knowledge of this condition is important as it can pre-empt unnecessary further investigations and biopsy. Although imaging appearance may be striking, close imaging follow-up and clinical monitoring are often enough for the management of this entity.
幕上开颅术后颅内出血可呈典型的模式和部位,这可能提示诊断为远隔性小脑出血(RCH),这是一种相当罕见的情况。“斑马征”指的是一种高密度影模式,呈曲线状、条纹状沿小脑叶片分布,高密度影提示出血,低密度影提示正常小脑实质,是RCH的特征性影像学表现。一般来说,RCH不需要手术治疗,然而,在出现明显脑积水或意识进行性恶化的情况下,可能需要进行手术治疗。了解这种情况很重要,因为它可以避免不必要的进一步检查和活检。尽管影像学表现可能很明显,但密切的影像学随访和临床监测通常足以对该疾病进行管理。
