Patients with cerebral stem tumors have subacute onset, while patients may present with nausea and vomiting, as well as somatic symptoms and signs, and patients may sometimes have headache, which can be clearly diagnosed by cranial MRI. If inflammation of the cerebellar brainstem is considered, the patient may have a subacute onset and may have an elevated body temperature, and if necessary, an electroencephalogram or cerebrospinal fluid may be extracted for pathogenic examination to clarify the diagnosis.
