Cavitary Hodgkin Lymphoma of the Lung.

It has been shown that some cases of Hodgkin lymphoma (HL) may present with pulmonary parenchymal involvement usually in the form of multiple irregularly marginated pulmonary nodules. Other radiographic patterns such as consolidation, interstitial infiltrates, and cavitary lesions are less common. We present a case of HL, nodular sclerosis type, with pulmonary involvement presenting as a large cavitary consolidation and axillary and mediastinal lymphadenopathy. Initial diagnostic work-up including sputum culture, bronchoscopy, and a fine needle aspiration of lymph node was not conclusive favoring a reactive process with a presumptive diagnosis of cavitary pneumonia. A follow-up chest imaging revealed worsening right upper lung mass, axillary adenopathy, and new nodular satellite lesions, and a repeat bronchoscopy with multiple biopsies remained non-diagnostic requiring an excisional biopsy of the axillary lymph node confirming HL. Further transthoracic core biopsies of the cavitary lung lesion were consistent with pulmonary lymphoma involvement.
