Atraumatic Spontaneous Splenic Rupture With Unknown Etiology

Splenic rupture of all causes is a potentially life-threatening event for patients. The infrequency of atraumatic splenic rupture (ASR) poses a significant diagnostic challenge due to atypical findings. ASR is commonly due to a spleen with an underlying disease process such as malignancy, infection, coagulopathies, or neoplasms. However, ASR without an identifiable cause is rare and poses further complexity. In this case, a 57-year-old woman with a history of hypertension presented to the emergency department complaining of chest pain and was found to have a splenic hematoma. She underwent splenic artery embolization due to her continued hemodynamic instability. The patient was ultimately treated with a splenectomy, as embolization was unsuccessful. Gross pathology revealed no underlying disease processes, nodules, or masses. Splenic hemorrhage due to atraumatic rupture of the spleen is rare and without known pathology. The case illustrates the need for providers to have high clinical suspicion of such a diagnosis to stabilize and surgically manage these patients. Few instances of ASR without an identifiable cause are found in medical literature, and further knowledge of the subject is needed.
