“…This should move either anterograde or retrograde in the bowel. On radionuclide GI bleeding studies, a variety of abnormalities such as hemangiomas, varices, aneurysms, and angiodysplasia may be detected incidentally [9,10]. In the present case, abnormal radioactivity extending from the epigastric region to the true pelvis was shown immediately after the administration of the radiotracer, which did not migrate or change in shape or intensity on subsequent delay images.…”

Ectopic varices (EcV) are enlarged portosystemic venous collaterals, which usually develop secondary to portal hypertension (PHT). Mesocaval collateral vessels are unusual pathways to decompress the portal system. Here we report the case of a huge varicose inferior mesenteric vein (IMV) that drained into perirectal collateral veins, demonstrated by (99m)Tc-labeled red blood cell (RBC) scintigraphy performed for lower gastrointestinal (GI) bleeding in a 14-year-old girl. This case illustrates the crucial role of (99m)Tc-labeled RBC scintigraphy for the diagnosis of rare ectopic lower GI varices.

“…Other potential pitfalls that have been reported include varices, abdominal/gluteal hematomas, aortic aneurysms, and hemangiomas. [7][8][9][10][11][12][13][14] In this case, the omental hernia caused compression on adjacent blood vessels, resulting in altered blood flow and mimicking gastrointestinal bleeding on 99m Tc-RBC scintigraphy. This case emphasizes the importance of considering anatomical anomalies and nonbleeding pathologies when interpreting 99m Tc-RBC scintigraphy results for gastrointestinal bleeding.…”

Gastrointestinal bleeding scintigraphy is a noninvasive study used to determine the presence of active bleeding, localize the bleeding site, and estimate the bleeding volume for prognostic purposes in patients with suspected gastrointestinal bleeding. However, it is important to note that false-positive results can occur due to various reasons. In this case, we present the scenario of a middle-aged woman who exhibited symptoms of gastrointestinal bleeding and underwent 99mTc-RBC scintigraphy. The imaging revealed an accumulation of radiotracer in the hypogastric region, which was later determined to be caused by an omental hernia on SPECT/CT images. The herniated structure caused congestion in the mesenteric vessels, leading to the accumulation of 99mTc-RBC. This case highlights the significance of considering anatomical anomalies and nonbleeding pathologies when interpreting the 99mTc-RBC scintigraphy results for gastrointestinal bleeding.

“…There are several reports of arterial leaks mimicking gastrointestinal bleeding (82)(83)(84)(85)(86)(87). In addition, the literature reports a number of case reports demonstrating aortoduodenal fistula rupture (88), hemangiomas in the liver or small bowel (89,90), and abdominal varices (92,94). Varices are most commonly seen as static blood pool structures, but they can also rupture and cause bleeding (91,93,95).…”
