Its cutaneous metastases are extremely rare, accounting for 0.0002% of all cases. The ventriculoperitoneal (VP) shunt has been considered a potential route for tumor dissemination. This type of tumor proliferation has been well documented in patients with intra-abdominal metastases secondary to brain tumors and, less frequently, brain metastases secondary to intra-abdominal tumors. In spite of that, there are few reports of cutaneous metastases along the VP shunt catheter trajectory. We present the case of a cholangiocarcinoma cutaneous metastasis at the VP shunt trajectory as the first clinical sign of this type of tumor. The patient had undergone the shunt insertion 4 years earlier due to a hydrocephaly secondary to a subarachnoid hemorrhage. After diagnosis, she was referred to chemotherapy and oncology follow-up. In the literature, 30 cases of cutaneous metastasis of cholangiocarcinoma were reported. Dissemination has been described involving percutaneous biliary drainage and distant sites. However, the case presented in this study alerts us about the possibility of cutaneous metastasis of intra-abdominal tumors in the trajectory of VP shunt catheters.

However, in some cases, there may be surgical revisions and requirement of an alternative distal site for shunting. There are several described distal sites, and secondary options after VPS include ventriculopleural and ventriculoatrial shunt, which have technical difficulties and harmful complications. OBJECTIVES: In this preliminary report we describe our initial experience with retrograde ventriculosinus shunt (RVSS) after failed VPS. RESULTS: In 3 consecutive cases we applied RVSS to treat hydrocephalus in shunt-dependent patients who had previously undergone VPS revision and in which peritoneal space was full of adhesions and fibrosis. RVSS was performed as described by Shafei et al., with some modifications to each case. All 3 patients kept the same clinical profile after RVSS, with no perioperative or postoperative complications. However, revision surgery was performed in the first operative day in 1 out of 3 patients, in which the catheter was not positioned in the superior sagittal sinus. CONCLUSIONS: We propose that in cases where VPS is not feasible, RVSS may be a safe and applicable second option. Nevertheless, the long-term follow-up of patients and further learning curve must bring stronger evidence.
