P10 developed sinusoidal obstructive syndrome without reversal of flow on ultrasound or fulfillment of Baltimore criteria, but histologically proven on day +22 liver biopsy performed for hyperbilirubinemia that additionally showed nodular regenerative hyperplasia (presumed to have been present pre-BMT due to prior 6-mercaptopurine treatment), cholestasis of sepsis, and mild hemosiderosis.
