Splenic tuberculosis in an immunocompetent patient can be managed conservatively: a case report

Tuberculosis is a significant health problem in developing countries. Splenic tuberculosis usually occurs as a part of miliary tuberculosis, and ranks third after lung and liver involvement, respectively. Splenic involvement is more common in immunocompromised patients and is very rarely found in immunocompetent patients. Here we report a case of splenic tuberculosis in an immunocompetent patient, which was managed successfully with conservative treatment.

Spontaneous splenic rupture in an acute leukemia patient with splenic tuberculosis: A case report

Spontaneous splenic rupture, also referred to as atraumatic splenic rupture, is a rare but life-threatening emergency condition. Without timely diagnosis and treatment, the mortality rate of splenic rupture approaches 100%. The etiology of atraumatic splenic rupture varies; it is reportedly associated with neoplasms or splenic infection, but is rarely encountered in patients with both conditions. We herein report the case of a 58-year-old male patient with acute myeloid leukemia (AML) complicated by splenic tuberculosis (TB), who presented with spontaneous rupture of the spleen. Pathological examination of the resected spleen revealed multifocal granulomatosis with caseous necrosis. However, with timely diagnosis and surgical intervention, the patient recovered successfully and is currently on consolidation therapy. To the best of our knowledge, this is the first case of spontaneous splenic rupture in AML with splenic TB. The relevant literature on spontaneous splenic rupture was also reviewed and the potential etiology and treatment were discussed.

The Role of Contrast-Enhanced Ultrasound in Differentiating Splenic Tuberculosis From Splenic Lymphoma

AIM

To summarize the features of splenic tuberculosis and splenic lymphoma by contrast-enhanced ultrasound (CEUS) and examine the application of CEUS in differentiating splenic tuberculosis from splenic lymphoma.

METHODS

The ultrasound and CEUS manifestations of 30 cases of splenic tuberculosis and 19 cases of splenic lymphoma were retrospectively analyzed, and the number of lesions, degree of splenomegaly, internal echogenicity, color blood flow signal, and CEUS manifestations of the two diseases were statistically determined.

RESULTS

A significant difference was noted in the internal echogenicity between splenic tuberculosis and splenic lymphoma lesions, particularly the strip-shaped hyperechoic areas of the lesions. The ultrasound features of perisplenic, retroperitoneal, and superficial lymph node enlargement were found to overlap (p < 0.05). Splenic tuberculosis showed heterogeneous enhancement and non-enhancement, whereas lymphoma showed low enhancement and high enhancement, and CEUS findings were statistically significant in distinguishing both, p < 0.05.

CONCLUSION

Splenic tuberculosis is characterized by a lack of blood supply, mostly heterogeneous enhancement, and non-enhancement noted in CEUS. Splenic lymphoma lesions are often characterized by a rich blood supply and homogeneous enhancement on CEUS. CEUS can help identify the microcirculation of lesions in both patients with splenic lymphoma and patients with splenic tuberculosis. Thus, CEUS has great application value.

Isolated Splenic Tuberculosis in an Immunocompetent Patient: A Rare Case

Tuberculosis (TB) is one of the top 10 causes of death worldwide and the leading cause of death from a single infectious agent. Despite early diagnosis and improvements in medical science, the incidence of the disease is still a major public health problem in developing countries. Splenic tuberculosis is quite rare and occurs mostly as a part of miliary tuberculosis in individuals with immunosuppression. Isolated splenic tuberculosis is extremely rare in immunocompetent patients. We report a case of an immunocompetent man with isolated splenic tuberculosis.

Splenic abscess as a rare symptom of the extrapulmonary tuberculosis - case report

INTRODUCTION

Extrapulmonary tuberculosis can involve any organ or tissue. It is a rare disease in the Czech Republic with an incidence rate of 0.62 cases per 100.000 persons. It affects mostly immunocompromised patients. The most common sites include lymph nodes, the urogenital system, skin, joints, bones and serous epithelium - the peritoneum, pleura, and pericardium. Splenic involvement is rare. Mycobacterium is a slow growing intracellular parasite. The diagnostic process is very difficult; microbiological diagnosis is critical.

CASE REPORT

An 84 years old female patient with subcapsular splenic rupture with no trauma history as a cause of anemia. Splenic abscess was diagnosed during surgical revision and splenectomy. Tuberculosis was suspected based on subsequent histological analysis, which was confirmed after nine weeks of peritoneal fluid culture. The surgical procedure and postoperative hospitalization were not associated with any complications. The patient was referred to the respiratory clinic for further treatment.

CONCLUSION

The diagnosis of extrapulmonary tuberculosis including splenic localization should always be considered. A sample from the affected tissue or effusion must be collected in the case of unclear perioperative findings and sent for complete bacteriological testing, including mycobacterial culture. If a tuberculous splenic abscess is found, the therapeutic process should involve its complete drainage in combination with long-term anti-TB medication.
