Wcn26-8030 Diffusion Tensor Imaging Suggests Biphasic Medullary Changes in an Extrarenal-Symptomatic Acute Post-Streptococcal Glomerulonephritis Case

Acute post-streptococcal glomerulonephritis (APSGN) typically presents with hematuria, edema, and hypertension. Although short-term outcomes are generally favorable, several long-term studies have reported that a subset of patients later develop hypertension, proteinuria, or renal dysfunction, suggesting that prognosis is not uniformly benign. APSGN remains one of the most common causes of acute glomerulonephritis in children worldwide, yet imaging-based evaluation of subtle renal microstructural changes has been limited.
