Recurrent Breast Cerebrospinal Fluid Pseudocyst: A Complication of Ventriculoperitoneal Shunt Placement

Ventriculoperitoneal (VP) shunt complications involving the breast are rare, with the majority involving the formation of a cerebrospinal fluid pseudocyst. We present the case of a 22-year-old woman with recurrent cerebrospinal fluid pseudocyst secondary to fracture of a VP shunt at the time of breast surgery for breast asymmetry. We review the literature on this topic and present our case that highlights the need of the breast surgeon to take into account the position of VP shunts placed at birth. Shunts placed on the chest wall may result in breast asymmetry requiring surgery in the adolescent. Shunts in place since birth may be at greater risk of fracture during breast implant placement due to manipulation of a calcified and fragile shunt leading to formation of a cerebrospinal fluid pseudocyst.
