Sonography of emphysematous pyelonephritis
Abstract:
Emphysematous pyelonephritis is a rare gas-producing bacterial infection of the renal parenchyma seen primarily in patients with diabetes mellitus. Sonographic findings in four patients with this disease are described. Sonographic features consist of multiple high-amplitude echoes within the renal parenchyma, renal sinus, and/or perirenal space accompanied by acoustic shadowing. Computed tomography confirmed bilateral involvement in one case. Plain abdominal radiographs demonstrated abnormal extraluminal gas in three of four cases. The role of sonography in diagnosis is discussed.
Insights
Emphysematous pyelonephritis, a rare bacterial kidney infection causing gas, primarily affects diabetic patients. Ultrasound reveals characteristic echoes and shadowing, aiding diagnosis.
Area of Science:
- Nephrology
- Radiology
- Infectious Diseases
Background:
- Emphysematous pyelonephritis is a severe, gas-producing bacterial infection of the kidney.
- It predominantly affects patients with diabetes mellitus.
Observation:
- This study describes sonographic findings in four patients diagnosed with emphysematous pyelonephritis.
- Key sonographic features included high-amplitude echoes and acoustic shadowing within the renal parenchyma, sinus, and perirenal space.
Findings:
- Ultrasound demonstrated characteristic echogenic patterns and shadowing.
- Computed tomography confirmed bilateral kidney involvement in one case.
- Plain abdominal radiographs showed abnormal extraluminal gas in three out of four patients.
Implications:
- Sonography plays a crucial role in the diagnosis of emphysematous pyelonephritis.
- Early detection through imaging can lead to timely intervention and improved patient outcomes.
- Understanding these imaging findings is vital for clinicians managing diabetic patients with suspected kidney infections.
