The diagnosis of brain stem tumours is mainly based on clinical findings and CT examinations: The CT examination including intravenous or intrathecal administration of contrast media together with electronic image-reconstruction greatly influences the indications for direct operation. According to our interpretation, direct surgical treatment is apparently successful under the following circumstances: - in tumours with external growth, which allows a decompression of the tumour without harming the surrounding structures in the brain stem. - in tumours with a marked cystic component, especially if the compressive effect is causing the features and progress of the symptoms.
脑干肿瘤的诊断主要基于临床表现和CT检查：包括静脉或鞘内注射造影剂以及电子图像重建的CT检查，极大地影响了直接手术的适应证。根据我们的解读，在以下情况下直接手术治疗显然是成功的：- 肿瘤呈外生性生长，在不损害脑干周围结构的情况下可对肿瘤进行减压。- 肿瘤有明显的囊性成分，尤其是当压迫效应导致症状出现及进展时。
