During his admission, he had an ultrasound of the abdomen followed by a CT thorax, abdomen and pelvis which showed splenomegaly and a large splenic lower pole mass that was hypoechoic and concerning for lymphoma. A bone marrow biopsy showed no evidence of lymphoma and an ultrasound-guided biopsy of the splenic mass suggested unusual features with vascular proliferation, either neoplastic or reactive, with no evidence of lymphoma or high-grade sarcoma. Given the concern for malignancy, an open splenectomy was required to determine the nature of the lesion with histologic findings consistent with a non-neoplastic benign vascular lesion favouring sclerosing angiomatoid nodular transformation.
