PRESENTATION After fainting in the lavatory, a healthy 59-year-old woman was taken to the hospital, where she would ultimately receive an unexpected diagnosis. On admission, she reported that she had been experiencing epigastric pain radiating to the left shoulder for several hours.
low blood pressure ( 100 mm Hg) correctly stratified this patient’s syncope as high risk.1 Although not specific, the presence of neutrophilia can be regarded here as a marker for the severity of bleeding.2 Splenic rupture may occur without blunt abdominal trauma. Usually, it takes place in the setting of an infectious or neoplastic disease involving the spleen, though other etiologies may underlie these rare, so-called pathologic,
ASSESSMENT The patient’s physical examination was remarkable for pallor, blood pressure of 86/45 mm Hg that later increased to 100/60 mm Hg, and epigastric tenderness. An electrocardiogram, chest x-ray, and abdominal x-ray were each normal. Laboratory tests showed that her hemoglobin was 9.5 g/dL, and her neutrophil count was 14.5 109 cells/L. A rectal examination and gastroscopy were unremarkable except for a known diaphragmatic hernia, which was treated with pantoprazole. The patient’s hemoglobin dropped to 6.6 g/dL over 14 hours, and contrast computed tomography revealed free fluid in the abdomen, a large hematoma around the spleen, and active arterial bleeding (Figure). She had no history of trauma. Total splenectomy was immediately performed.
DIAGNOSIS While the patient’s spleen was normal in size (144 g) and results from histology and immunostaining were normal, it was ruptured and a massive subcapsular hematoma was evident. Few causes of syncope are more immediately lifethreatening—and more difficult to diagnose—than spontaneous occult acute arterial bleeding in a previously healthy patient. Her low initial hematocrit (< 30%) and persistently Funding: None. Conflict of Interest: None. Authorship: All authors had access to the data and wrote the paper.

ruptures (Table).3,4 Nontraumatic splenic rupture in a patient with an apparently healthy spleen also has been reported, but fortunately, this is an exceedingly unusual event.5 Nevertheless, its occurrence in soldiers and other fit young people highlights the existence of true idiopathic splenic rupture of unknown pathogenesis.5
MANAGEMENT Our patient’s signs and symptoms were investigated and diagnosed rapidly. After splenectomy, she made a complete recovery, and she has remained well over 4 years of follow-up. Our report emphasizes the need for heightened awareness of spontaneous splenic rupture. Although uncommon, it can be fatal and thus demands swift intervention. Once suspicions are raised for this condition, CT
is the mainstay of diagnosis and should be performed without delay.3,5
