Upon detecting a mural nodule, we diagnosed it as a cerebellar HB and completely resected it using an endoscopic keyhole approach. The patient's symptoms alleviated postoperatively.

A 23-year-old man presented with a self-inflicted stab wound on the left side of his neck from a kitchen knife. This injury resulted in hemorrhagic shock and coma. Initial management included fluid resuscitation and transfusion, with continuous manual compression to control profuse bleeding. Contrast-enhanced neck and brain computed tomography (CT) showed a left CCA injury that was challenging to directly address due to its low anatomical location and continuous bleeding. Neurosurgeons initiated endovascular treatment by placing a guiding balloon catheter proximal to the left CCA for occlusion. Despite this, pulsatile bleeding persisted, prompting the distal placement of a balloon catheter to achieve better bleeding control. Cardiovascular surgeons then performed direct surgery, clearly identifying damage to the anterior and posterior walls of the CCA. The repair involved the use of a self-made cylindrical bovine pericardial patch, which resulted in successful revascularization.

The gradual reduction in the pressure difference between the arachnoid cyst and the subdural hygroma due to long-term CSF drainage and inflammation caused by meningitis may have contributed to close arachnoid membrane laceration.
