Contained abdominal aortic rupture secondary to follicular lymphoma invasion

An 87-year-old woman with grade IIIb follicular lymphoma treated with rituximab had presented with nausea, emesis, and chest pain of 1 day duration. She was found to have a contained abdominal aortic rupture secondary to follicular lymphoma invasion. She safely and successfully underwent emergent endovascular aortic repair. We have described a rare case of extranodal disease in follicular lymphoma associated with abdominal aortic pseudoaneurysms, likely due to a combination of malignancy-induced chronic inflammation and radiation therapy and chemotherapy side effects.
