Splenic hemangioendothelioma (SH)

Clinical Notes

Hemoglobin – 7.6 (low)
Platelet – 436K (high)
WBC – 23.7K (high)
human chorionic gonadotropin – <1 (normal)
alpha feto-protein – 11.5 (normal)


US – Large hypervascular exophytic splenic mass, slightly hypoechoic to the spleen.

CT – Confirms slightly heterogeneous isodense splenic origin mass.

MRI – Mass is hypointense to spleen on T2 and hyperenhancing on post-gadolinium images.


SH is a very rare tumor with low malignant potential previously thought to represent angiosarcoma. Patients are often young adults with no gender predilection who present with a palpable mass and hypersplenism. Diagnosis is unlikely to be made by imaging alone.
