    Splenectomy can alter liver shape and position, leading to misinterpretations on liver scans. These post-splenectomy changes may mimic other conditions, causing diagnostic confusion.

    Area of Science:

    • Hepatology
    • Radiology
    • Surgical Oncology

    Background:

    • Splenectomy is a common surgical procedure.
    • Post-splenectomy imaging findings can be atypical.
    • Accurate interpretation of liver scans is crucial for patient management.

    Purpose of the Study:

    • To describe changes in liver morphology and function after splenectomy.
    • To highlight potential misinterpretations of liver scans in post-splenectomy patients.
    • To present illustrative cases of diagnostic challenges.

    Main Methods:

    • Retrospective review of liver scans in patients who underwent splenectomy.
    • Analysis of imaging findings and correlation with clinical data.
    • Case study approach to illustrate specific misinterpretations.

    Main Results:

    • Observed changes in liver shape, position, and colloid uptake post-splenectomy.
    • Identified specific patterns leading to misinterpretation, including left lobe migration.
    • Demonstrated mimicry of residual/accessory spleen, porta hepatis masses, and recurrent disease.

    Conclusions:

    • Post-splenectomy anatomical and functional liver changes can complicate scan interpretation.
    • Awareness of these alterations is essential to avoid diagnostic errors.
    • Further studies may be needed to standardize imaging protocols in this patient group.
