A Hispanic Female With a Right Retroperitoneal Mass

A 49-year-old Hispanic woman presented for evaluation of a right 4.4 x 4.2  2.9 cm retroperitoneal (retrocaval) extra-adrenal mass found during an abdominal pain workup (see images). Plasma metanephrine testing was negative (total free metanephrines, 183) and a computed tomography-guided biopsy revealed a spindle cell neoplasm. She elected to proceed with surgical resection for definitive management.
