Adult colorectal intussusception

Colon Lipoma Causing Colo-Colic Intussusception in an Adult: A Case Report from Tanzania

“…Computed tomography having a sensitivity of 71–87% and a specificity of up to 100% remains the preferred radiological modality for the diagnosis of intussusception [ 13 , 14 ]. It allows for the clear identification of the intussuscepting tissue as well as the lead point, presenting the typical appearance known as the “target sign” or “sign of donut” as seen in our case [ 12 , 15 ]. Studies have shown the use of MRI being superior due to its effectiveness in highlighting adipose lesions because of the peculiar characteristics of the signal intensity of this tissue, especially T1-weighted and fat-suppressed images [ 4 , 16 ].…”

Splenic flexure colonic lipoma causing intussusception

“…Computed Tomography remains the tool of choice for the diagnosis of intussusception as it allows the clear identification of the intussuscepting tissue as well as the lead point. 9,10 However, determining the aetiology of the intussusception on Computed Tomography remains a challenge. 7 Colonic lipomas appear as well demarcated ovoid shaped lesions.…”

Partial spontaneous anal expulsion of the right colon lipoma: An exceptional diagnostic circumstance

“…Lipomatous lesions remain asymptomatic for a long time. Non-specific symptoms may occur when they measure more than 2 cm; colonic occlusion may then happen either by reducing intestinal lumen or by promoting colo-colic or ileo-colic intussusceptions in adults [5] . Low digestive haemorrhage and diarrhea are infrequent manifestations [6] .…”
