Clinical presentation

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.

Radiograhphic features


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.
