Patients are usually asymptomatic but may present with varied symptoms related to the implantation site. The diagnosis is a challenge because abdominal splenosis can mimic several diseases, including neoplasm. The gold standard examination for its diagnosis is scintigraphy with 99mTc-labelled heat-denatured erythrocyte. When splenosis is found in an asymptomatic patient, surgical removal is not indicated. A 57-year-old male patient presented with sporadic epigastric pain and a suspected mass in the recto-sigmoid transition. Abdominal ultrasound, CT and MRI identified this mass, its characteristics and location, but failed to distinguish its nature. However, given the patient\u2019s past history of splenectomy and because the mass showed a similar sign to that of the splenic parenchyma, a hypothesis of abdominal splenosis was raised, which was confirmed by scintigraphy with 99mTc-labelled heat-denatured erythrocyte. In this case, the diagnosis was obtained before the patient was subjected to more invasive procedures, which are associated with high morbidity, and, as in most cases, no targeted intervention was necessary.<\/jats:p>","DOI":"10.12890\/2021_002219","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T09:52:37Z","timestamp":1621936357000},"source":"Crossref","is-referenced-by-count":3,"title":["Abdominal Splenosis Mimicking a Colon Tumour"],"prefix":"10.12890","volume":"8","author":[{"given":"Joana","family":"Braga","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Hospital Santa Maria Maior, Barcelos, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Pereira","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Hospital Santa Maria Maior, Barcelos, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristiana","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Hospital Santa Maria Maior, Barcelos, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marinha","family":"Silva","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Hospital Santa Maria Maior, Barcelos, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa","family":"Boncoraglio","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Hospital Santa Maria Maior, Barcelos, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Hospital Santa Maria Maior, Barcelos, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10397","published-online":{"date-parts":[[2021,1,18]]},"reference":[{"key":"10.12890\/2021_002219_ref1","doi-asserted-by":"crossref","unstructured":"<li>Gupta K, Ahluwalia A, Jain T, Saggar K.
