Acute Lobar Nephronia: A Review

This is the authors' abstract. We don't add key points for this paper.

Acute lobar nephronia was described by Rosenfield et al1 in 1979. Subsequently, numerous reports2-5have appeared in the radiologic literature. Also called acute focal bacterial nephritis, this newly defined condition has only recently been described in the pediatric literature.6,7 Because of the focal nature of acute lobar nephronia, it may be confused with an intrarenal abscess. This is especially true when the usual imaging techniques used to investigate urinary tract infections are applied. Acute lobar nephronia is an acute, nonsuppurative renal infection that represents progression of acute pyelonephritis. Because of major differences in the management of acute lobar nephronia and intrarenal abscess, it is important to distinguish these two conditions.
