Splenic haemangiomatosis

Splenic haemangiomatosis involves multiple, diffuse splenic hemangiomas replacing its entire parenchyma. It is a very rare entity.

It can occur as a manifestation of systemic angiomatosis or, less commonly, confined to the spleen (diffuse isolated splenic haemangiomatosis). There is total or subtotal replacement of the splenic parenchyma by a vascular proliferation featuring the usual morphological findings of hemangiomas.

Reported associations include

Patients may clinically present with 

Non sensitive and non specific but may show

  • calcifications in left hypochondriac region
  • features of splenomegaly

May show

  • solid hyperechoic masses
  • complex echogenic mass with cystic areas
  • splenomegaly
  • non contrast - well defined iso-hypodense masses
  • post contrast -  lesions show homogenous enhancement

Signal characteristics of individual lesions include

Typical uncomplicated lesions

  • T1: most are hypo-isointense while some are hyper intense
  • T2: hyper- intense

There is variable intensity if there is associated thrombosis, infarction and/or hemorrhage

In general, diffuse splenic hemangiomatosis is a benign lesion and may have an asymptomatic course. It however can present with associated complications such as some of those mentioned above.
