False positive GI bleed on Tc-99m RBC scintigraphy due to ileal varices.
Tc-99m labeled RBC scintigraphy is commonly employed in the evaluation of acute gastrointestinal bleeding. On Tc-99m RBC studies gastrointestinal bleeding is seen as an initial focus of increased radiotracer activity that on subsequent images increases in intensity and changes position in a pattern that conforms to segments of bowel. We report a case of a patient with multiple episodes of hemat...
متن کامل99mTc-RBC Scintigraphy for diagnosis of intestinal stromal tumor hemorrhage: a case report
Background: Gastrointestinal stromal tumors (GISTs) are rare and our understanding of the natural history and optimal treatment of GISTs are continually evolving. They are characterized by a remarkable cellular variability and their malignant potential is sometimes difficult to predict. Case presentation: We report the case of intestinal stromal tumor in a 44 years old patient with a long histo...
متن کاملDetecting aorto-ureteric fistula by 99mTc-Labeled Red Blood Cell SPECT
A 68-year-old male, known case of abdominal aortic dissection and recent aortic stent insertion, presented with gross hematuria. The urologists suspected aoro-ureteric fistula and performed open surgery (ureterolysis). Tc-99m labeled red blood cell (99mTc-RBC) scintigraphy was ordered to confirm the diagnosis and localize the possible aorto-ureteric fisula, Considering sustained gros...
متن کاملAgreement of two methods of planar and SPECT scintigraphy with 99mTc- RBC in detection of liver hemangioma [Persian]
Introduction: Hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mTc- RBC scan is highly specific and is the method of choice for this differentiation. This scintigraphy is performed in Planar and SPECT modes. These two procedures are in agreement most of the times, however since SPE...
