title: Pulmonary Nodular Lymphoid Hyperplasia presenting cavitating pulmonary nodules.
abstract: Pulmonary Nodular Lymphoid Hyperplasia (PNLH) is a rare benign pulmonary disorder characterized by a localized, reactive polyclonal lymphoproliferation. Although the radiological features of this disease have not been clearly defined, they usually consist of a solitary non-cavitatory pulmonary nodule. In this report, we describe two cases of histologically confirmed PNLH presenting as multiple bilateral cavitatory lesions on CT Thorax.
