Haemangiopericytoma of the spleen

Haemangiopericytomas of the spleen are very rare vascular neoplasm with only a few case reports available at the time of writing.

Splenic haemangiopericytomas are typically asymptomatic or can result in splenomegaly.

These are soft tissue vascular neoplasms arising from capillary pericytes 1. It is often characterised as having variable biologic behaviour, but it is regarded as a tumour that may have very high malignant potential 3.

Since the tumours are very rare, with only occasional case reports describing the imaging findings.

  • a large splenic mass with polylobular contours
  • smaller disseminated lesions throughout the spleen 3

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.
