Laboratory findings in patient A before and after adenoma resection.

(A) An MRI scan performed prior to resection (August 30, 2000) shows a 13 × 14 cm adenoma in the left lobe of A's liver (arrow). (B) Individual panels illustrate changes in hematocrit, serum ferritin concentration, serum iron concentration, and erythrocyte sedimentation rate for approximately 1 year before and 6 months after resection (performed December 15, 2000). The serum ferritin was initially above the normal range but fell to subnormal levels after the tumor was resected, and erythroid iron utilization returned to normal.
