Pseudolymphoma of the liver associated with primary biliary cirrhosis: A case report and review of literature

Multinodular pseudolymphoma of the liver: computed tomography and magnetic resonance imaging findings

“…[1][2][3][4][5] Most of the lesions reported are single in number, although multiple lesions have been also reported. [1][2][3][4][5] Usually there are just two or three lesions, however, with a large number of lesions as in our case never having been reported to the best of our knowledge.…”

“…[1][2][3][4][5] Imaging fi ndings of PL, although only a few case reports are available, are thought to refl ect these pathological features but are considered nonspecifi c. On CT, a hypodense mass on unenhanced images that is slight enhanced on early-phase images after contrast injection and subsequent washout have been reported. [1][2][3][4][5] On angiography, neovascularity and tumor stain have been documented. 4 On MR imaging, low signal intensity on T1-weighted images and slightly high signal intensity on T2-weighted images have been reported.…”

“…4 On MR imaging, low signal intensity on T1-weighted images and slightly high signal intensity on T2-weighted images have been reported. 1,4,5 Thus, imaging fi ndings of PL are nonspecifi c for any vascular hepatic lesions, including hepatoma, hypervascular In the present report, fi ndings on diffusion-weighted MRI (DWI) and Gd-EOB-DTPA-enhanced MRI were newly presented. The lesions showed high signal intensity on DWI with an apparent diffusion coeffi cient (ADC) value of 0.6-0.7 × 10 mm 2 /s, which may refl ect its high cellularity of the lesion.…”

“…Its association with autoimmune disease, malignancy, and hepatitis has been reported. [1][2][3][4][5] The imaging fi ndings of PL are nonspecifi c and resemble those for any other vascular tumors of the liver, which make its noninvasive diagnosis diffi cult. We herein present a case of multinodular PL in which a small vessel was observed to course within one of the lesions on multidetector row computed tomography (MDCT), and partial uptake of liver-specifi c contrast agent was observed in the lesion on magnetic resonance imaging (MRI), both of which might be characteristic of hepatic PL.…”
