CT appearance of endobronchial non-Hodgkin lymphoma.

Objective: Endobronchial involvement by non-Hodgkin lymphoma (NHL) is a very rare manifestation of the disease. We describe this unusual entity and emphasize the role of chest CT scan.

Methods: Two radiologists reviewed the chest radiographs and CT scans of two patients with endobronchial NHL. The studies were reviewed for the presence and extent of endobronchial involvement. Bronchoscopic confirmation was obtained.

Results: In each case CT showed endobronchial lesions that correlated well with the extent of tumor found at bronchoscopy.

Conclusions: Computed tomography is useful to suggest endobronchial NHL in the proper clinical context and to assist the bronchoscopist in selecting the appropriate site for biopsy.
