Acute Glomerulonephritis


Acute glomerulonephritis causes edema due to diffuse parenchymal inflammation leading to renal enlargement. Contrast-enhance CT is contraindicated in these patients--ultrasound is the diagnostic modality of choice. Imaging studies are usually non-specific and may show only smooth bilateral renal enlargement during the acute phase of the disease. Diagnosis usually requires a biopsy. The role of imaging in these patients is to exclude obstruction as the cause of renal insufficiency that may be reversible with urinary tract decompression.
