Case Report: Transient renal medullary hyperechogenicity in a term neonate

摘要

Although neonatal renal medullary hyperechogenicity can occur in a variety of pathological conditions, it has been reported to occur transiently with or without renal abnormalities in term as well as in preterm neonates. Variably described in the literature as Tamm-Horsfall nephropathy, or stasis nephropathy, the pathogenesis is unknown, but has an excellent prognosis. The authors describe a 3-day-old neonate with transient renal medullary hyperechogenicity, with no other abnormalities, which resolved within 2 weeks.
