An egg shell-like retroperitoneal pseudocyst.

摘要

Retroperitoneal pseudocysts are rare entities. Egg shell-like calcified retroperitoneal pseudocyst is rarer. We report a 75-year-old woman with an egg shell-like calcified retroperitoneal pseudocyst. Subsequently, the calcified pseudocyst was dissected and excised completely through laparoscopy via a retroperitoneal approach.
