Metastatic malignancy mimics: a rare case of traumatic splenosis mimicking intra-abdominal malignancy

Metastatic malignancy mimics: a rare case of traumatic splenosis mimicking intra-abdominal malignancy:

We present a case of a patient, undergoing imaging for an unrelated presentation, whose adolescent abdominal trauma had caused an unrecognised disseminated intra-abdominal splenosis, resulting in an imaging presentation on CT that suggested intra-abdominal malignancy. The lack of correlative symptoms of disseminated malignancy, in addition to imaging findings suggesting previous upper abdominal trauma, led to a suggestion that the intra-abdominal lesion might represent spleen tissue. A denatured red cell scan with radio-labelled technetium-99m, allowed this tissue to be confirmed as splenic in nature, and an invasive, and potentially risky biopsy was averted.
