Tuberculosis versus vasculitis.
J Ayub Med Coll Abottabad Jan ;26(4):630-2.

Vasculitis (Wegeners Granulomatosis and Microscopic Polyangiitis) and Tuberculosis share many features including constitutional symptoms and respiratory tract involvement. The presence of kidney involvement with new onset azotaemia and active urine sediment support the diagnosis of vasculitis. We describe two cases that were diagnosed to be suffering from tuberculosis and placed on anti-tuberculosis therapy. On further workup they were found to be suffering from pauciimmune glomerulonephritis and recovered well with treatment.
