Haemagiopericytoma of spleen
A hemangiopericytoma of the spleen is is a very rare vasular neoplasm with only a few case reports available at the time of writing.
A splenic hemangiopericytoma is typically asymptomatic or can result in splenomegaly
As with heamangiopericytoma's in general is a soft tissue vascular neoplasm arising from capillary pericytes 1. It is often characterized as having variable biologic behavior, but it is regarded as a tumor that may have very high malignant potential 3.
Since the tumors are very rare only occasional case reports have described imaging findings.
Reported CT findings include 3
- a large splenic mass with polylobular contours or
- smaller disseminated lesions throughout the spleen
Speckled calcification may be seen on CT scans, and contrast-enhanced studies may show discrete hyperattenuation of solid portions and septation.
It was first reported by Guadalajara Jurado et al in 1989 4
