Recurrent Hepatic Inflammatory Pseudotumor in Asynchronism After Surgery of Inflammatory Pseudotumor Associated With Granulomatous Cholangitis

Abstract

A 64-year-old man was referred to our hospital for investigation of thickening of the gallbladder wall and hepatic mass. Repeated endoscopic ultrasound-guided fine-needle aspiration examinations of these lesions excluded malignant diseases. Cholecystectomy and resection of lateral section confirmed xanthogranulomatous cholecystitis and inflammatory pseudotumor (IPT) associated with granulomatous cholangitis. Ten months after surgery, a new lesion appeared in the liver medial section, associated with fluorodeoxyglucose accumulation. After performing resection of the affected segment, recurrent IPT related with granulomatous cholangitis was diagnosed. No subsequent recurrence was seen during follow-up. This represents the first report of recurrent hepatic IPT originating from granulomatous cholangitis after resection of xanthogranulomatous cholecystitis and IPT caused by granulomatous cholangitis.
