Inflammatory pseudotumors in the liver associated with influenza: A case report

Figure 1 Computed tomography of the Abdomen and Pelvis illustrating the interval changes of the hepatic inflammatory pseudotumor in a span of 3 mo. A: A 5.0 cm × 3.0 cm mildly hypodense hepatic mass on computed tomography (CT) A/P dual phase liver; B: A 1.9 cm × 1.3 cm mildly hypodense hepatic mass (previously 5.0 cm × 3.0 cm) on CT A/P dual phase liver; C: A 1.1 cm × 1.1 cm right hepatic lobe mass on CT A/P dual phase liver; D: Resolution of the 1.1 cm × 1.1 cm right hepatic lobe mass (visualized in C).

Figure 2 Whole body fluorodeoxyglucose-positron emission tomography/computed tomography illustrating overall uptake of left lobe hepatic masses similar to the remainder of the liver.

Figure 3 Ultrasound-guided fine-needle aspiration of the liver mass visualized on computed tomography. A: Core biopsy of the liver mass; B: Core biopsy showing lymphoplasmacytic infiltrate and absence of malignant cells; C: Core biopsy with replacement of multiacinar liver parenchyma by fibrous and myxoid stroma with dense lymphoplasmacellular infiltrate; D: Core biopsy visualizing benign hepatocytes.
