title: The CT halo: a new sign in active pulmonary sarcoidosis.
abstract: A case of pulmonary sarcoidosis is presented characterized by multiple coalescent nodules and peripheral ground glass halos, which were fully reversible under repeat systemic glucocorticoid treatment. The differential diagnostic aspects of the pulmonary CT halo sign and its potential for indicating active reversible disease in patients with sarcoidosis is discussed.
