They typically present as solitary submucosal lesions, most frequently located in the proximal colon, and generally measure less than 2 cm in diameter. When their size exceeds 4 cm, they are defined as giant lipomas and may become symptomatic, causing nonspecific gastrointestinal manifestations such as abdominal pain, bloating, constipation, or intermittent bleeding. We report the case of a patient with abdominal pain predominantly localized to the right upper quadrant, with symptom onset approximately two weeks earlier. Intestinal ultrasound revealed a well-defined colonic mass associated with features suggestive of intestinal intussusception. Subsequent contrast-enhanced computed tomography (CT) demonstrated a fat-density intramural lesion consistent with a colonic lipoma and confirmed the presence of colonic invagination. The patient subsequently underwent laparoscopic right hemicolectomy, which was performed without perioperative complications. Histopathological examination confirmed the diagnosis of a submucosal lipoma. This case highlights the potential role of intestinal ultrasound as an initial diagnostic tool in the evaluation of bowel pathology. Although computed tomography remains the imaging modality of choice for definitive characterization and preoperative assessment, ultrasound may provide valuable early diagnostic clues, facilitating timely diagnostic confirmation and appropriate management.</p>","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148220555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores the epidemiology, pathophysiology, and molecular mechanisms of PG development.

The pathogenesis involves sustained inflammation, leading to fibrosis, scarring, and ultimately calcium deposition. At the molecular level, pro-inflammatory cytokines, macrophage activation, and fibroblast differentiation ultimately result in collagen deposition and calcification. Estrogen contributes to female predominance through reduced gallbladder motility and increased cholesterol secretion via ESR1, ESR2, and GPER1 receptors. Postmenopausal women remain at risk despite lower estrogen levels due to antioxidant system changes and structural alterations from previous pregnancies. Emerging evidence suggests roles for Helicobacter pylori and other urease-producing bacteria in PG development. The relationship between calcification patterns and malignancy remains controversial, with incomplete calcification potentially carrying higher cancer risk.
