Abstract

Purpose: The aim of this study was to characterize the CT features of retroperitoneal neurilemmoma.

Methods: The CT findings were reviewed in seven patients with retroperitoneal neurilemmoma.

Results: All of the tumours were well-demarcated round or oval masses. In five cases, heterogeneous contrast enhancement was noted after contrast medium administration. Areas of minimal enhancement reflected diffuse edema in one tumour. Areas without definite enhancement represented prominent cyst formation in three tumours. There were three cases with tumour calcification (two with punctate calcification and one with mottled calcification).

Conclusion: CT findings may suggest the diagnosis of retroperitoneal neurilemmoma preoperatively.
