INFLAMMATORY PSEUDOTUMOR OF THE LIVER - APPEARANCE ON MRI

Inflammatory pseudotumor of the liver is a rare entity; fewer than 50 cases have been reported in the world literature. Its appearance on bo th computerized tomography (CT) and ultrasound have been previously de scribed. To our knowledge, this is the first report of its appearance on magnetic resonance imaging (MRI). The lesion demonstrated increased signal intensity on T-1 and T-2 spin-echo and inversion recovery (STI R) sequences in relationship to normal liver. The signal characteristi cs, however, were nonspecific and diagnosis required biopsy confirmati on. There was spontaneous resolution with conservative management, and this was documented on follow-up CT and MRI.
