Abstract

Mediastinal inflammatory pseudotumor is a rare benign disease with its capability for local invasion and rapid growth. We present a case of middle-mediastinal inflammatory pseudotumor and report its contrast-enhanced chest computed tomography, $^{18}F$-fluorodeoxyglucose positron emission tomography/computed tomography and pathologic findings.
