Abstract:
Various pathologies could lead to occult gastrointestinal (GI) bleeding. Here we report the case of a 73-year-old woman who presented with hematochezia and syncope, and was found to have a large bleeding GI stromal tumor incidentally from 99m Tc-RBC scintigraphy. This study was done after negative workup with CT angiography, colonoscopy, and capsule endoscopy for the source of GI bleeding. Final pathology confirmed the mass being a low-grade GI stromal tumor after exploratory laparotomy.
