| 摘要 |
A 50‑year‑old male presented with sudden‑onset headache, diplopia, and unsteadiness due to a posterior fossa hemorrhagic melanoma causing hydrocephalus. Computed tomography of the brain showed a 2.3 cm × 2.0 cm hemorrhagic tumor in the cerebellar vermis and a concomitant fourth ventricular
hemorrhage. He underwent removal of the tumor and then ventriculoperitoneal shunt insertion for hydrocephalus. Because of his widespread disease, the patient died 2 weeks later from multiple massive intratumoral hemorrhages. To avoid this unfortunate consequence, we discuss the mechanism and suggest
methods for treatment improvement. The variable we could control carefully was the opening pressure of the shunt and the flow of cerebrospinal fluid drainage. Setting a higher opening pressure and changing the pressure more slowly should be considered. To achieve this goal, the use of a programmable valve and
anti‑siphon system should strongly be recommended in these high‑risk populations with extremely high bleeding tendency. |
