[Vascular proliferations of the spleen].
Vascular proliferations of the spleen reflect the variability of vascular structures occurring in the normal spleen. Besides haemangiomas, there is a spleen-specific vascular neoplasm, littoral cell angioma, that often occurs as a paraneoplastic lesion and thus may require the differential diagnostic delineation of metastases to the spleen in patients with known neoplasms. The most common malignant vascular tumours of the spleen are angiosarcomas. A recently described vascular lesion of unknown pathogenesis, sclerosing angiomatoid nodular transformation (SANT) of the spleen, usually is an incidental finding detected in the course of imaging studies.
