Inflammatory Pseudotumor of the Liver with Escherichia coli in the Sputum
Sreenath Narayan, Ashwini Nayak, Chris L. King
TL;DR
This paper describes a case where a liver lesion resembling cancer was linked to an Escherichia coli infection.
Contribution
The paper presents a novel case linking E. coli infection to inflammatory pseudotumor in the liver.
Findings
A liver lesion was observed to rapidly erode into the lung.
Sputum cultures revealed Escherichia coli growth.
Pathology confirmed the lesion as an inflammatory pseudotumor.
Abstract
Inflammatory pseudotumor is a nonmalignant lesion that mimics malignant lesions and has been reported to occur at various sites throughout the body. Though it has been reported as a reaction to infection, the true etiology of the lesion is unknown. In this report, we present the case of a patient with a liver lesion of unknown origin. Through a series of imaging studies, we were able to observe the locally aggressive nature of this lesion as it rapidly eroded into the lung. Sputum cultures showed growth of E. coli, indicating E. coli infection as a possible etiology of this lesion. Pathology was consistent with inflammatory pseudotumor.
