Abstract

Ciliated hepatic foregut cyst (CHFC) is a rare benign lesion consisting of ciliated pseudostratified columnar epithelium, loose subepithelial connective tissue, a smooth muscle layer, and an outer fibrous capsule. We encountered a patient with retroperitoneal and posterior mediastinal neurilemmoma and additional CHFC mimicking metastasis. Abdominal CT examination demonstrated that the posterior mediastinal and retroperitoneal lesions were lobulated, well-defined tumors with a neural foraminal extension that were pathologically confirmed as neurilemmomas. Unenhanced CT indicated that the additional lesion was a slightly hypodense mass relative to surrounding parenchyma at the medial segment of the left lobe of the liver, and after the IV ad-ministration of contrast material, the lesion did not show enhancement.
