Cavernous malformations in the midbrain can be accessed via several safe entry zones. The accepted rule of thumb is to enter at the point where the lesion is visible at the surface of the brainstem to pass through as little normal brain tissue as possible. However, in some cases, in order to avoid critical neural structures, this rule may not apply. A different safe entry zone can be chosen. Our video presents a case of a ruptured cavernous malformation in the midbrain reaching its anterior surface which was successfully resected via a posterolateral route using the supracerebellar infratentorial approach.

中脑海绵状畸形可通过多个安全入路进行处理。公认的经验法则是在脑干表面可见病变的部位进入，以尽可能少地穿过正常脑组织。然而，在某些情况下，为了避免重要神经结构，这一规则可能不适用。可以选择不同的安全入路。我们的视频展示了一例中脑海绵状畸形破裂至其前表面的病例，该病例通过小脑上幕下入路经后外侧途径成功切除。视频可在此处找到：https://youtu.be/j7VTqRO7qd4 。
