Spontaneous Splenic Rupture: The Masquerade of Minor Trauma

Refractory splenic bleeding from splenic angiosarcoma: A case report and literature review

Introduction and importance

Atraumatic splenic rupture (ASR) is a rare state that accounts for only <1 % of splenic ruptures. One of the causes of ASR is splenic neoplasm such as angiosarcoma. The treatment strategy for ASR is still unclear given the small number of cases reported in detail.

Case presentation

A 75-year-old woman presenting with abdominal pain with shock was referred to our hospital. Emergency computed tomography revealed splenic rupture, and hemodynamic stabilization was obtained by emergent vascular embolization. Rebleeding occurred 27 days after the initial treatment, and splenectomy was performed. Pathologically, ASR was diagnosed as caused by splenic angiosarcoma.

Clinical discussion

ASR is a very rare disease. The etiology of ASR has been reported as neoplastic, infectious, and so on. The treatment for ASR should be decided considering the etiology of ASR, hemodynamic stability, volume of blood transfusion, patient status, severity of the splenic injury, and volume of intraperitoneal bleeding.

Conclusions

We experienced a very rare case of ASR, in which diagnosis was challenging and the timing of surgery was difficult to determine. When splenic rupture has an atraumatic cause, splenectomy should be considered because of the possibility of malignancy.

•

The treatment strategy for traumatic splenic rupture is conservative therapy if possible, but that for atraumatic splenic ruptures has not been elucidated.

•

In the case of conservative treatment for atraumatic splenic rupture, pathological examination cannot be performed, which may leave the patient untouched if the disease is malignant and at risk of rebleeding.

•

Given the challenging diagnostics of angiosarcoma, splenectomy should be considered early in cases of atraumatic splenic rupture.

Spleen angiosarcoma: a world review

Introduction: Spleen angiosarcoma (SA) is a rare malignant neoplasm that arises from the splenic vascular endothelium, with only around 300 cases reported to date. Due to a limited number of reported cases, there is a paucity of data and a lack of understanding of its presentation, diagnosis, and management. In this study, we aim to provide a comprehensive review of SA.Areas covered: On 27 February 2021, a literature search was done in PubMed and Embase database. The search yielded 122 articles involving 205 patients. The focus was on patient demographics, risk factors, clinical presentations, investigation results, preliminary diagnoses, therapies provided, and patient outcomes. These factors were analyzed to identify possible risk factors, diagnostic modalities, and therapeutic principles that were not mentioned before.Expert opinion: The clinical presentation or investigation results of patients with SA are often nonspecific. Hence, they may not be sufficient to clinch the diagnosis of SA if used alone. The authors recommend a triple assessment of clinical examination, imaging findings, and pathology to diagnose SA with high accuracy. Splenectomy should be the mainstay of management, with chemotherapy and radiotherapy considered as adjuncts, especially in the presence of metastases.

Unexpected death due to spontaneous splenic rupture: A rare case in splenic angiosarcoma

Splenic angiosarcoma (SA) is a rare disease that can cause spontaneous splenic rupture leading to unexpected death. The rare incidence and non-specific clinical presentations made the early correct diagnosis of SA impossible in clinical practice. Even with medical intervention, 80% of patients died within 6 months after diagnosis. Here, we report a man who had complained of abdominal distension for 2 weeks and succumbed to the disease nine hours after admission. Diagnosis of hepatic and splenic angiosarcomas was based on post-mortem histopathological examination and immunohistochemistry, and the cause of death was hemorrhagic shock caused by spontaneous splenic rupture secondary to SA. This present case was the first forensic autopsy of spontaneous splenic rupture secondary to SA, which can highlight the diagnosis of rare diseases in forensic practice, and forensic pathologists should bear in mind these rare diseases even in routine practice.

A Case of Splenic Peliosis Associated with Pathologic Rupture

A patient walked into the accident and emergency department with spontaneous onset of left-sided abdominal pain. Physical examination suggested the presence of an acute abdominal condition. He was admitted to the surgical ward with a provisional diagnosis of perforated peptic ulcer. Emergency laparotomy revealed haemoperitoneum caused by rupture of the spleen. Pathologic examination confirmed the rare diagnosis of splenic peliosis. Emergency physicians should be aware of the possibility of atraumatic splenic rupture as a cause of spontaneous haemoperitoneum, bearing in mind that isolated splenic peliosis (also known as peliosis lienis) is one of the causes of pathologic splenic rupture.

Splenic rupture in community acquired pneumonia: A case report

•

Splenic rupture is a rare complication of community acquired pneumonia.

•

Clinician vigilance is required to prevent subsequent morbidity and mortality.

•

Post-operative follow-up must address the potential sequelae of asplenia.

•

This research did not receive any specific funding and the authors declare no conflicting interests.

Introduction

Splenic rupture is a rare but potentially lethal complication of community acquired pneumonia.

Presentation of case

We present an unusual case of haemorrhagic shock following splenic rupture requiring emergency splenectomy in a 49 year old female with community acquired pneumonia.

Discussion

The epidemiology, aetiology, pathogenesis, clinical features, investigation, management and outcomes of atraumatic splenic rupture are discussed.

Conclusion

Atraumatic splenic rupture is a rare but potentially fatal complication of numerous disease processes including pneumonia. A high index of suspicion and a thorough and systematic approach to the deteriorating patient is required to prevent related morbidity and mortality. Post-operative follow-up must address the potential sequelae of asplenia.

613 cases of splenic rupture without risk factors or previously diagnosed disease: a systematic review

BACKGROUND

Rupture of the spleen in the absence of trauma or previously diagnosed disease is largely ignored in the emergency literature and is often not documented as such in journals from other fields. We have conducted a systematic review of the literature to highlight the surprisingly frequent occurrence of this phenomenon and to document the diversity of diseases that can present in this fashion.

METHODS

Systematic review of English and French language publications catalogued in Pubmed, Embase and CINAHL between 1950 and 2011.

RESULTS

We found 613 cases of splenic rupture meeting the criteria above, 327 of which occurred as the presenting complaint of an underlying disease and 112 of which occurred following a medical procedure. Rupture appeared to occur spontaneously in histologically normal (but not necessarily normal size) spleens in 35 cases and after minor trauma in 23 cases. Medications were implicated in 47 cases, a splenic or adjacent anatomical abnormality in 31 cases and pregnancy or its complications in 38 cases. The most common associated diseases were infectious (n = 143), haematologic (n = 84) and non-haematologic neoplasms (n = 48). Amyloidosis (n = 24), internal trauma such as cough or vomiting (n = 17) and rheumatologic diseases (n = 10) are less frequently reported. Colonoscopy (n = 87) was the procedure reported most frequently as a cause of rupture. The anatomic abnormalities associated with rupture include splenic cysts (n = 6), infarction (n = 6) and hamartomata (n = 5). Medications associated with rupture include anticoagulants (n = 21), thrombolytics (n = 13) and recombinant G-CSF (n = 10). Other causes or associations reported very infrequently include other endoscopy, pulmonary, cardiac or abdominal surgery, hysterectomy, peliosis, empyema, remote pancreato-renal transplant, thrombosed splenic vein, hemangiomata, pancreatic pseudocysts, splenic artery aneurysm, cholesterol embolism, splenic granuloma, congenital diaphragmatic hernia, rib exostosis, pancreatitis, Gaucher's disease, Wilson's disease, pheochromocytoma, afibrinogenemia and ruptured ectopic pregnancy.

CONCLUSIONS

Emergency physicians should be attuned to the fact that rupture of the spleen can occur in the absence of major trauma or previously diagnosed splenic disease. The occurrence of such a rupture is likely to be the manifesting complaint of an underlying disease. Furthermore, colonoscopy should be more widely documented as a cause of splenic rupture.

Non-traumatic splenic rupture: Report of seven cases and review of the literature

AIM: To evaluate seven patients with non-traumatic splenic rupture (NSR). NSR is an uncommon dramatic abdominal emergency that requires immediate diagnosis and prompt surgical treatment to ensure the patient’s survival.

METHODS: Within 11 years, seven cases were evaluated for patient characteristics, anamnesis and symptoms, method of diagnosis, findings of laparotomy, and etiology of NSR.

RESULTS: There were six (86%) male and one female (14%) patient, whose mean age was 36 ± 12.8 (17-56) years. We report here four cases of Plasmodium vivax malaria (cases I-IV), one case of hemodialysis (case V), one case of spontaneous splenic rupture (case VI), and one case of hairy cell leukemia (case VII). Splenectomy was performed in all patients. All of them made an uneventful recovery and were discharged in stable condition.

CONCLUSION: NSR is a rare entity that needs a high index of suspicion for diagnosis. Using ultrasonography or computer tomography, and peritoneal aspiration of fresh blood may assist in the diagnosis of NSR. Increased awareness of NSR can enhance early diagnosis and effective treatment.

Rupture of the spleen or splenic vessels (splenic emergency syndrome) in late pregnancy: a report of two autopsy cases

Emergencies of splenic origin in pregnancy involving rupture of the splenic artery or hemorrhage are rare events that can present suddenly and unexpectedly. We report two cases of young women, both in the third trimester of gestation, who suffered sudden malaise while at home and were admitted to the ER. On arrival, both were in severe hemorrhagic shock due to gross hemoperitoneum and they died in the operating theatre during emergency surgery. To better clarify the causes and sequence of these mortalities, forensic autopsy was requested in each case. In the first (a 26-year-old primigravida in the 40th week of pregnancy), cadaveric section demonstrated the rupture of an aneurysm of the splenic artery. In the second (a 28-year-old multipara in the 33rd week of pregnancy), the clinical and anatomopathological data suggested splenic hemorrhage. In both cases histology showed a fibrodysplasia of the arterial wall involving the splenic artery in one case and the hilar branches in the other. In agreement with the data in literature, in such cases particular importance must be attributed to examination of the arterial wall. In pregnancy a synergic effect between hemodynamic and endocrine factors can cause degeneration of the arteries resulting in dramatic hemorrhage. From the forensic pathologist's viewpoint, these cases underline the importance of histopathological study of the splenic artery in the interpretation of the pathogenesis of splenic vessel rupture or hemorrhage.
