We report a case of a primary mesenteric tumor that was discovered in a 71-year-old man. Abdominal US accurately visualized the internal structure of the tumor but failed to determine the site of origin. Computed tomography suggested the mesenteric origin of the tumor before resection. The mass was removed and histopathological examination (including immunohistochemical and ultrastructural studies) was consistent with a primary gastrointestinal stromal tumor (GIST) of the mesentery, a very rare neoplasm scarcely reported in the radiology literature. Clinical, radiological, and pathological findings of this case are presented and the topic of primary mesenteric tumors with phenotypical features of GIST is reviewed.

Extra-cavitary primary effusion lymphoma (PEL), often associated with human herpes virus 8 (HHV8) infection, represents a rare and aggressive form of non-Hodgkin lymphoma, which is predominantly found in individuals with severe immunosuppression. As an acquired immunodeficiency syndrome (AIDS)-associated lymphoma, PEL typically manifests in the context of advanced human immunodeficiency virus (HIV) infection, requiring tailored therapeutic approaches to manage both the lymphoma and underlying immunodeficiency. A 53-year-old male patient from Cape Verde presented with a three-day history of fever, night sweats, right iliac fossa pain, hematochezia, and an unintentional weight loss of five kilograms over the previous two months.

Background: Image-defined risk factors (IDRFs) were introduced to provide a consensus approach for pre-treatment risk stratification on computed tomography (CT) and magnetic resonance imaging (MRI) in patients with neuroblastoma.
Objective: To assess the intra- and inter-reader agreement of radiologists in identifying IDRFs on CT.
Materials And Methods: Approval for this retrospective study was granted by our institutional research ethics board with a waiver of consent.

Small intestinal neuroendocrine tumors (SI-NETs) typically follow an indolent disease course and are often accompanied by mesenteric lymph node metastases upon diagnosis. These tumors can incite a fibroblastic reaction within the mesenteric root. Here, we present two cases of patients with symptomatic small bowel obstruction due to such mesenteric involvement.

Introduction And Importance: Peritoneal inclusion cysts (PICs), also known as peritoneal mesothelial cysts, are rare, benign cystic lesions primarily occurring in the abdominopelvic cavity of premenopausal women with histories of pelvic surgery or inflammation. These cysts can present with nonspecific symptoms and may mimic other abdominal pathologies, making diagnosis challenging.
Case Presentation: A 41-year-old male with no significant medical history, who experienced progressive nonspecific abdominal pain over several months.
