Pulmonary Nodular Lymphoid Hyperplasia presenting cavitating pulmonary nodules

Area of Science:

• Pulmonology
• Pathology
• Radiology

Background:

• Pulmonary Nodular Lymphoid Hyperplasia (PNLH) is a rare, benign condition involving lymphoproliferation in the lungs.
• The typical radiological presentation involves a solitary, non-cavitatory pulmonary nodule.

Observation:

• This report presents two cases of histologically confirmed PNLH.
• Both cases exhibited unusual imaging findings on CT Thorax.

Findings:

• The PNLH cases presented as multiple bilateral cavitary lesions.
• This presentation deviates significantly from the commonly described solitary nodule.

Implications:

• These findings expand the spectrum of radiological appearances for PNLH.
• Radiologists and clinicians should consider PNLH in the differential diagnosis of multiple cavitary lung lesions.
