A Rare Case of Tuberculosis Masquerading as Collapsing Glomerulopathy

Abstract

Collapsing glomerulopathy (CG), usually presents with renal dysfunction, hypertension and proteinuria. The etiology is uncertain, yet a number of associations, including many viral infections commonly have been reported. Tuberculosis (TB), one of the most common infections, is not known to cause CG. We report a case of severe renal dysfunction requiring dialysis who had collapsing glomerulopathy on biopsy and evidence of active pulmonary tuberculosis. Anti-tubercular therapy alone resulted in improvement in kidney function.
