Xanthogranulomatous cholecystitis (XGC) is a rare form of chronic gallbladder inflammation that most commonly presents as acute cholecystitis and is often mistaken for carcinoma of the gallbladder. This case details the hospital course and follow-up of a 77-year-old male who developed suspected acute acalculous cholecystitis (AAC) resulting in severe sepsis after elective left total knee arthroplasty (TKA). Histopathological findings after elective cholecystectomy later revealed XGC as the underlying etiology., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, League et al.)

Congenital absence of the left pulmonary artery remains a rarely reported anomalous condition and is even less commonly seen in conjunction with a right-sided aortic arch. While most cases are identified during prenatal fetal ultrasonography and require early childhood intervention, some asymptomatic cases can go unrecognized until incidentally detected on chest imaging as an adult. This case details a 31-year-old male with a congenital absence of the left pulmonary artery and right-sided aortic arch with subsequent atretic and fibrotic lung, all found on imaging during admission for acute alcoholic hepatitis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, League et al.)
