Overview
Rupture of the spleen is a serious medical condition manifesting as a sudden abdominal event, potentially life-threatening. Spontaneous spleen rupture is a rare condition. Atraumatic rupture of the spleen is a very unlikely condition. Risk factors include splenomegaly, hemato-oncological diseases, and infections, such as malaria or infectious mononucleosis. Extremely rare is splenic rupture described in autoimmune disease or vasculitis. There has been no reported case of spontaneous splenic rupture as a first manifestation of Churg- Strauss syndrome so far.

Introduction
Rupture of the spleen is a serious medical condition manifesting as a sudden abdominal event, potentially life-threatening (1). In most cases, rupture of the spleen is a result of a trauma. Spontaneous spleen rupture is an extremely rare condition and is usually not taken into consideration in the differential diagnosis of acute abdominal pain (1-2). In this report, we present a clinical case of spontaneous spleen rupture in a patient with unknown autoimmune vasculitis, as a first manifestation of disease.
Clinical Case
A 52-year-old woman with previous history of asthma bronchial disease was examined at the emergency department with abdominal pain and repeated vomiting. She gave a history of fatigue, weight loss of 8 kg, pain in the upper abdomen lasting for months. She indicated regular use of prednisone, PPI, and diuretics. Clinical examination pointed pain in epigastrium. Laboratory tests showed serious hyponatraemia (119 mmol/l) and hypochloraemia (85 mmol/l), normocytic anaemia, and elevated level of C-reactive protein (50mg/l). Patient was admitted to the internal clinic for substitutional treatment and differential diagnosis. Due to persisting abdominal pain with negative X-ray of abdomen, contrast- enhanced CT examination was performed. CT showed a hemoperitoneum, hematoma in the spleen with active arterial bleeding (Figures No.1 and 2). The patient has repeatedly denied recent injury or trauma. Subsequently, she was moved to the surgical department and referred to acute surgical exploration. Laparotomy verified a hemoperitoneum with approximately 500ml of blood and coagulum, with a 5cm hematoma of the spleen with superficial rupture and leakage of blood. A splenectomy was performed. During awakening from anaesthesia, the patient had an episode of hemoptysis. In the context of this information, we began to search the pathological conditions. She made a good recovery without any other complications. We performed a complex differential diagnosis, examination of blood, urine (with the finding of erythrocyturia), and autoantibodies. Hemato-oncological malignancies and inflectional diseases like EBV, CMV were excluded. Definitive histology has shown the picture of necrotising eosinophilic granulomatosis arteritis, which may correspond with a diagnosis of Churg-Strauss syndrome (Figures No.3 and 4). Patient was immediately referred to rheumatological examination.
Discussion
Atraumatic rupture of the spleen is an extremely rare condition, with an estimated prevalence of 0,1-0,5 %, twice more common in men (3). Risk factors include splenomegaly, hemato-oncological diseases, and infections, such as malaria or infectious mononucleosis (4). Splenic ruptures are extremely rarely described in autoimmune diseases, such as Wegener granulomatosis, lupus erythematosus, and polyarteritis nodosa (5). There has been no reported case of spontaneous splenic rupture as a first manifestation of Churg- Strauss syndrome so far. Of course, the possibility of an injury that the patient is not aware of must also be taken into account.
Churg - Strauss syndrome (also known as eosinophilic granulomatosis with polyangiitis) is a very sporadic condition presented as disseminated necrotizing vasculitis and extravascular granulomas (6). This syndrome typically occurs in patients with preexisting asthma and eosinophilia and affects small or medium-size vessels of any organs (7). Together with Wegener’s granulomatosis and microscopic polyangiitis belong to vasculitis associated with the presence of antineutrophil cytoplasmatic autoantibodies (ANCA) (8). According to available papers, traces of ANCA antibodies have been found in 40-75% of patients. Estimated incidence is approximately 2,5 cases per 100 000 adults per year. The average age of patient is 50 years (9). Diagnosis can be difficult. The American College of Rheumatology suggested six criteria for diagnosis Churg-Strauss syndrome: presence of asthma, eosinophilia of more than 10 % in peripheral blood, paranasal polyps or sinusitis, pulmonary infiltrates, histological proof of vasculitis with extravascular eosinophils and mononeuritis multiplex (or polyneuropathy) (10). The prognosis depends on the start of the treatment. Without treatment, 5-year survival rate of patients is about 25% (11). The disease is obscure, with minimal symptoms and a variable clinical picture. Spleen involvement is rare and usually presents as splenic infarction. There is no reported case of asymptomatic splenic rupture associated with Churg-Strauss disease.
Conclusion
Spontaneous spleen rupture is an extremely rare condition and usually is not considered in the differential diagnosis of acute abdominal pain. In this report, we presented a clinical case of spontaneous spleen rupture in a patient with unknown Churg-Strauss disease, as a first manifestation of disease.
