Fig.1: Axial T2 with fat saturation MR image shows a slightly T2 hyperintense lesion in the spleen (arrow).
Fig.2: Axial T1 post contrast with fat saturation reveals homogeneous enhancement of this lesion.
- Solid versus cystic (distinguish by T2 signal intensity and enhancement pattern)
- If solid, is it classic for hemangioma? Is there a history of malignancy elsewhere?
- If cystic, usually represent false cyst (post-traumatic), congenital cyst, abscess
- Benign tumors: hemangioma (most common benign tumor of spleen, same character as liver hemangioma), hamartoma
- Malignant tumors: lymphoma, metastasis (history, multiplicity)
- Others: sarcoidosis, langerhans cell histiocytosis
