Suprarenal retroperitoneal liposarcoma with intracaval tumor thrombus: an imaging mimic of adrenocortical carcinoma.

[dedifferentiated liposarcoma]

We report a 57 -year -old previously healthy man who presented with dull right upper quadrant pain , weight loss , fatigue , and night sweats . Computed tomography demonstrated a large , heterogeneously enhancing , soft tissue mass with no macroscopic fat above the right kidney with tumor thrombus extending into the inferior vena cava and right atrium . Positron Emission Tomography scanning demonstrated intense Fluorodeoxyglucose avidity in the primary tumor and tumor thrombus . The presumptive radiological diagnosis was adrenocortical carcinoma , but surgical pathology revealed a dedifferentiated liposarcoma . We conclude that suprarenal retroperitoneal liposarcoma should be included in the differential diagnosis for an apparent adrenal mass with venous invasion .
