Atraumatic Splenic Rupture due to Chronic Myelomonocytic Leukemia Treated with Partial Splenic Artery Embolization

We describe a patient with chronic myelomonocytic leukemia (CMML) who presented to the emergency department for acute abdominal pain and was found to have an ASR. He underwent partial SAE, with postoperative complications of leukocytosis and tumor lysis syndrome (TLS) requiring rasburicase and allopurinol. On follow-up in clinic 2 months post-discharge, the patient was doing well on hydroxyurea, without need for further intervention at that time. In patients with hematologic malignancies presenting with abdominal pain and splenomegaly, it is important to consider ASR as a rare, but possible complication. To our knowledge, this is the only reported patient treated with SAE in the context of ASR from CMML, demonstrating that SAE can be an effective nonoperative strategy for treatment of CMML-associated ASR. This case report also highlights postoperative complications and management in this patient population, specifically a profound leukocytosis and TLS, for which close monitoring should be performed.Case Rep Oncol 2022;15:277 –284
