Hepatic inflammatory pseudotumor

Hepatic inflammatory pseudotumors (IPT) are rare benign hepatic lesions.

Most common in young adults with males affected more than females 7

Etiology is unknown 7

Hepatic IPT is often seen as a well-circumscribed, encapsulated inflammatory mass. 

Hepatic IPT characterized by a large population of polyclonal plasma cells with a variable amount of fibrosis, foamy histiocytes, and other chronic inflammatory cells 2.

Radiological findings are not characteristic and definitive diagnosis requires needle biopsy (sometimes insufficient 7) or surgery 3.

In most reported cases, they appear as hypoattenuating masses with a variable degree of hepatic enhancement 2

  • T1: hypointense
  • T2: hyperintense
  • T1C+: heterogeneous enhancement 7
