PURPOSE: To report the association of a mosaic enhancement pattern on contrast-enhanced CT or MR imaging and @entity99 ( @entity384 ) with acute inflammatory conditions affecting extrahepatic organs. METHODS: From 2007 to 2012, @entity1 with acute inflammatory diseases who underwent contrast-enhanced CT and/or MRI of the liver with a mosaic enhancement pattern were selected. Clinico-biological and other imaging features were collected at diagnosis and during follow-up. RESULTS: Sixteen @entity1 were included (15 @entity1 , median age 27  years; range 18-68). Five @entity1 (33  %) were receiving @entity7280 . Acute inflammatory diseases included @entity2885 (n   =   10), @entity788 (n   =   2), @entity55 (n   =   1), @entity295 (n   =   1), active @entity30 (n   =   1), and @entity1960 (n   =   1). Median white blood cell count was 13,250 cells/ L (range 11,500-18,000 cells/ L) and CRP level 94  mg/L (range 60-121  mg/L). Mosaic enhancement pattern was present in the whole liver and was prominent in the subcapsular areas. Four @entity1 underwent liver biopsy confirming @entity384 . Eleven @entity1 underwent follow-up imaging showing normalized aspect in 9/11 @entity1 after a median of 2  months. CONCLUSION: @entity697 of extrahepatic organs, associated with a marked systemic inflammatory syndrome should be added to the list of conditions causing a reversible @entity99 as manifested by a mosaic enhancement pattern on contrast-enhanced CT or MR imaging. KEY POINTS:     Acute @entity6687 /inflammatory diseases are a cause of transient @entity2468 .     In most @entity1 , @entity2468 was seen during both arterial and portal venous phase.     In all @entity1 , the mosaic enhancement pattern was diffuse, but more conspicuous in subcapsular areas.     @entity2468 was no longer seen after resolution of the @entity697 .     No liver biopsy should be performed.
