Learning objectives
1. Systematize the approach of non-traumatic focal lesions of the spleen to narrow the differential diagnosis through main and ancillary findings.
2. Briefly and deeply review the main focal lesions in symptomatic and asymptomatic patients and some of the "unicorns".
Background
The spleen is a solid organ that is part of the immune system which participates in the formation of hematopoietic cells; due to its low frequency of neoplastic diseases it is the "forgotten" abdominal organ. However, it is the site of benign and malignant pathology in both symptomatic and asymptomatic patients.
Findings and procedure details
Findings and procedure details
Non-traumatic focal splenic lesions are a true challenge to the radiologist because the majority of them are incidental findings in asymptomatic patients and their findings usually overlap. Lesions can be classified according to their number, size, composition (reflected in echogenicity, density and signal intensity), growth-rate and behavior with contrast agents. Ancillary sings like the spleen size, lymph nodes and vascular abnormalities are used to narrowing our differential diagnosis spectrum. We review the main findings of twenty different spleen focal lesions through...
Conclusion
Conclusion
Non-traumatic focal spleen lesions are a frequent finding in our daily work. Through a simple algorithm radiologist can provide a better diagnosis for the patient as well as recommendation for follow-up, biopsy or surgery to the referent colleague.
