Abstract
Wide range of benign and malignant lesions may affect the spleen,
thus complicating the development of a differential diagnosis that
includes both benign and malignant focal lesions (1).
Solid splenic masses are encountered in routine clinical practice
and cause a diagnostic dilemma. Lesions can be discovered incidentally
on imaging studies performed for another causes. Malignant solid splenic
lesions include lymphoma, leukemic infiltrates, metastases, and
angiosarcoma (2,3).
The most common benign solid splenic focal lesions are
hemangiomas, hamartomas, and granulomas (4,5).
When focal splenic lesions are discovered on imaging studies, a
splenic biopsy is often considered, particularly in patients with
extrasplenic malignancies. Because most splenic lesions that which are
found incidentally are benign, it might not be necessary to perform a
biopsy to all patients with a focal splenic lesions (1).
There is a risk of bleeding after a splenic biopsy due to the rich
blood supply of the spleen, and focal splenic lesions may not be
accessible to ultrasound-guided biopsy due to poor sonic window.
