Rare Colonic Lipoma Revealed Through CT Imaging: A Case Report
Author(s): MANJUNATHA YC, ANIL KUMAR SAKALECHA
Colonic lipomas are rare, benign tumors that are often asymptomatic but can present with vague gastrointestinal symptoms, such as abdominal pain or altered bowel movements. A 44-year-old male presented with left-sided abdominal pain and intermittent loose stools, with an otherwise unremarkable physical examination. Computed tomography (CT) Enteroclysis revealed a well-defined, rounded, sessile intraluminal mass with fat attenuation (Hounsfield units [HU] -40 to -20) and mild peripheral wall enhancement, located in the descending colon and arising from its posterolateral wall. Although these tumors are mostly benign, they can occasionally cause complications such as intussusception, obstruction, or, in rare cases, perforation. Treatment options include colonoscopic resection for pedunculated and accessible lesions, while larger or symptomatic sessile lesions require surgical intervention. The clinical relevance of recognizing colonic lipomas lies in distinguishing them from malignant tumors, such as colorectal cancer. Their characteristic imaging features, including fat attenuation, enable accurate diagnosis and help avoid unnecessary invasive procedures. Timely recognition of colonic lipomas ensures appropriate management and reduces the risk of misdiagnosis. This case report highlights the clinical and radiological findings of a colonic lipoma.
