Learning objectives 1) Imaging modalities for the characterisation of splenic lesion2)Imaging features used to characterise splenic lesions3)Pathognomonic imaging features that help differenciate benign, indeterminate, and potentially malignant splenic lesions4) To illustrate typical cases.
Read more Background The spleen, a lymphatic organ of mesodermal origin, consist of two histological compartments: the red and white pulp. Although the spleen is rarely the primary site of disease, it is often involved in inflammatory, hematopoietic, and metabolic disorders associated with immune and hematologic diseases.Functions of the spleen overlap those of other body organs, making it possible for a person to live without a spleen. Physiologically, the four major functions of the spleen include reserving, filtering, producing, and defending blood products.Within...
Read more Findings and procedure details Splenic lesions can be broadly categorized into soloid and cystic types. For cystic lesions, it is important to determine whether the cysts are solitary or multiple. Solitary cytic lesions of spleen are typically benign.If a solitary cyst is present within the spleen, the potential differenctial diagnosis are outlines below.1)Epithelial cysts are typically well defined and unilocular , with thin barely preceptible wall. They rarely exhibit calcifications and do not enhance on post contrast imaging.2)Pseudocysts are benign, well circumscribed , unilocular...
Read more Conclusion -Systemic imaging approach of splenic lesion helps in accurate delineation of benign lesions and proper selection of indeterminate lesion there by limiting unwanted intervention.-To aid in diagnosis and develop an appropriate differenctial diagnosis , a stepwise approach can be used. This involves first determining whether the lesions are solid or cystic, followed by assessing whether they are solitary or multiple-A solitary splenic cyst is typically benign and is generally categorized as either parasitic or non-parasitic.-Solitary solid splenic lesions include benign...
