A case of hereditary elliptocytosis associated with constitutional indocyanine green excretory defect

A 24-year-old woman was diagnosed as having hereditary elliptocytosis and post-transfusion hepatitis. On admission, a marked delay in indocyanine green (ICG) plasma clearance was noted while bromsulphalein excretion was almost normal. Even when her levels of serum bilirubin and transaminases were decreased to the normal ranges and a liver biopsy revealed no evidence of any liver cirrhosis or active hepatitis, ICG excretion still remained abnormal. These findings were compatible to those of constitutional ICG excretory defect.
