Importance of accurate imaging phase in two different patients: a 64-year-old female patient with fever of unknown origin and weight loss. Axial plane postcontrast abdominal CT image showed multiple hypodense nodules in the spleen (arrowheads) due to the inappropriate imaging phase. This pseudonodular appearance completely disappeared on the repeat CT scan performed in the portal venous phase (not shown). b 44-year-old male patient with chronic kidney disease presented with abdominal pain. Axial plane postcontrast abdominal CT showed hypodense infiltrative appearance in the spleen (asterisk), thought to be suspicious for lymphoproliferative disease involvement. c Abdominal CT of the same patient in (b) performed 18 hours after the first CT scan. Control abdominal CT image in a later phase demonstrated homogenization of the spleen parenchyma with no apparent lesion
