|
|
Purpose: To assess gallbladder (GB) wall thickening and periportal tracking on CT in patients with acute pyelonephritis (APN) by each kidney involvement.
Materials and Methods: A total of 117 patients diagnosed with APN by clinical examination and CT were included in this retrospective study. The patients were divided into three groups based on kidney involvement seen on CT: right APN, left APN, and bilateral APN. Two radiologists reviewed CT images in consensus for the presence of diffuse GB wall thickening and periportal tracking. The prevalence of these two manifestations was compared among the three groups.
Results: The prevalence of GB wall thickening in patients with right APN (26.4%) and bilateral APN (19%) was significantly higher than in patients with left APN (0%) (p < 0.016). The prevalence of periportal tracking in patients with right APN (15.1%) and bilateral APN (26%) was higher than in patients with left APN (3%), with a significant difference between patients with bilateral APN and left APN (p < 0.016).
Conclusion: GB wall thickening and periportal tracking are predominantly encountered on CT in patients with APN involving the right kidney (right and bilateral APN), and should be considered in differential diagnosis of diseases associated with GB wall thickening and periportal tracking.
