Clinical examination confirmed the presence of flaccid quadriparesis with preserved tendon reflexes. Routine laboratory parameters showed severe hypokalaemia. On further evaluation she was diagnosed to have type 1 renal tubular acidosis secondary to Sjogren's syndrome. Sicca symptoms were conspicuous by their absence.
