Figure 1. Preoperative plain spinal radiographs demonstrated L1 compression fracture (a). T2-weighted imaging on magnetic resonance imaging revealed a recent L1 vertebral compression fracture without spinal canal compromise (b). Plain spinal radiographs after balloon kyphoplasty reveal effective filling of cystic fracture cavity (c).

Figure 2. Magnetic resonance imaging showed disproportionately enlarged subarachnoid space hydrocephalus, such as ventriculomegaly with an Evans’ index of 0.35 (a), narrowing of the cerebrospinal fluid spaces near the vertex, and widening of the Sylvian fissure (b).

Figure 3. Postoperative three-dimensional computed tomography showed the programmable valve and catheter’s correct placement.
