They include primary and secondary neoplasms, as well as some non-neoplastic conditions that mimic tumors. Diagnosis is often challenging, though certain clinical and radiologic features can aid early identification. Here, we present a series of histopathologically confirmed mesenteric neoplastic and non-neoplastic lesions, highlighting representative imaging features and reviewing relevant literature, with emphasis on tomographic findings.  \nCategories: Radiology, Oncology  \nKeywords: diagnostic imaging, mesentery, neoplasm metastasis, neoplasms, tomography  \nIntroduction  \nThe mesentery is made up of a double layer of peritoneum and is subdivided into the true mesentery and the specialized mesentery. It contains multiple structures inside and its function is to connect the small intestine to the posterior wall of the abdomen, as well as connecting multiple organs to each other [1] .  \nMesenteric neoplasms are rare lesions and are mostly secondary in nature, mainly because their close relationship with vascular, lymphatic, and nervous structures and multiple intra-abdominal organs makes them an important route for tumor dissemination [2] . Secondary neoplastic involvement of the mesentery occurs through different routes that can occur simultaneously and include: direct, lymphatic, hematogenous, and peritoneal spread, giving rise to different neoplasms that may have a similar appearance and originate in intra-and extra-abdominal organs. However, there are also primary mesenteric neoplasms (some of which are benign) and inflammatory or infectious lesions that mimic neoplasms, but these are rare conditions and are usually very unlikely to be suspected [3] . The symptoms of primary, secondary, and inflammatory lesions are non-specific and include abdominal pain, weight loss, palpable masses, diarrhea, among others [1] .  \nThe differential diagnosis between these conditions is difficult and usually requires histopathological analysis for confirmation. However, diagnostic imaging (especially tomography) plays a fundamental role in identifying key findings that help narrow down the differential diagnoses, define the extent of the disease, and contribute to the appropriate treatment of patients [2] . The treatment and prognosis of lesions vary depending on the etiology and range from conservative management to surgery and targeted cancer treatment [4] .  \nThe following case series presents neoplastic and non-neoplastic mesenteric lesions, some histopathologically confirmed, from the San Vicente Foundation Hospital in Medellín, Colombia, accompanied by a review of the literature emphasizing tomographic findings.  \nCase Presentation  \nCase 1  \nA 48-year-old male with neurofibromatosis type 2 (NF2) presented to the ED after blunt abdominal trauma from a traffic accident. Examination revealed abdominal wall hematomas but normal vital signs and no peritoneal irritation. Laboratory tests were normal, including complete blood count and acute phase reactants (Table 1) .  \nHow to cite this article  \nMejia M , Zapata M , Acevedo Ramirez S , et al.
