A CT angiogram revealed no vascular disease, no aneurysm or any arteriovenous malformation. Since the patient's consciousness level was almost normal with only slight cerebellar ataxia bilaterally, and considering the influence of her anticoagulant therapy and thrombocytopenia, we deferred surgery and managed the treatment conservatively. Another important point is that upward transtentorial herniation is always a risk when the supratentorial drainage is performed without the evacuation of posterior fossa mass. Since the symptom caused by hydrocephalus was manageable, a conservative wait-and-watch strategy was applied in considerations of above factors. 4 Conclusion Conservative treatment targeting underlying pathophysiology and careful neurological and radiological examinations could be a reasonable treatment strategy for posterior fossa chronic subdural haematoma if the symptoms from the compression to the cerebellum and brainstem by the haematoma and obstructive hydrocephalus are tolerable enough.
