An Unusual Case of Cerebrospinal Fluid Pseudocyst in a Previously Augmented Breast

Cerebrospinal fluid (CSF) drainage catheters can cause a myriad of complications, in large part because they may migrate from their normal location to almost anywhere in the body. We present the unique case of a female patient who had previously undergone bilateral breast augmentation who experienced sudden painless swelling of her right breast 6 weeks after placement of a ventriculoperitoneal shunt. Radiologic examination demonstrated ensnarement of the distal aspect of the shunt around her implant, with subsequent formation of a CSF pseudocyst. Management of this patient included replacement of the shunt, drainage of the CSF pseudocyst, and preservation of the implant.
