Atraumatic Splenic Rupture in Uncomplicated Multiple Myeloma—A Case Report—

Abstract

A 68-year-old man was transported to our hospital with sudden onset of left-sided abdominal pain that occurred at bedtime. Upon admission, he showed abdominal distention and upper abdominal tenderness, without any evidence of trauma. Abdominal computed tomography revealed accumulation of perisplenic high-density fluid. Emergency laparotomy was performed, and he underwent splenectomy for a diagnosis of atraumatic splenic rupture. Intraoperative findings included extensive coagulation and splenic rupture extending from the serous surface to the parenchyma. Based on histopathological examination of the excised specimen, bone marrow examination, peripheral blood tests, and urinalysis, he was diagnosed with multiple myeloma. Atraumatic splenic rupture secondary to malignant hematological disorder is rare. We could not confirm domestic reports of splenic rupture caused by multiple myeloma in the literature. We report this rare case along with bibliographic comments.
