Aims and objectives
With ever-increasing use of cross-sectional imaging,
radiologists face with the challenge of characterizing incidental splenic lesions.
Most of the incidental splenic lesions on CT scan and MRI turn out to be benign in patients with no known malignancy.
In the other hand,
spleen is a relatively uncommon site for metastasis; therefore differentiating benign from malignant lesions is crucial in these instances.

Ultrasound-guided biopsy of splenic lesion is considered the diagnostic method of choice for problematic splenic lesions.
However,
limitations in spleen biopsy persuade radiologists to focus on noninvasive imaging of splenic lesions.

This study was conducted to characterize the incidental splenic lesions on cross-sectional imaging and to assess the role of various imaging features to differentiate benign from malignant lesions.
