Pulmonary nodular lymphoid hyperplasia presenting as cavitating lung mass

Area of Science:

• Pulmonology
• Pathology
• Radiology

Background:

• Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare benign condition.
• PNLH can present with imaging findings that resemble lung malignancies.

Observation:

• A case of PNLH is presented with a long-term progression of imaging findings.
• The lesion evolved from a ground glass opacity to a solid, cavitating mass.

Findings:

• Surgical proof confirmed the diagnosis of PNLH.
• The case demonstrates the potential for PNLH to mimic slow-growing primary lung cancer over time.

Implications:

• Recognition of PNLH imaging characteristics is crucial for accurate diagnosis.
• Distinguishing PNLH from lung cancer can prevent unnecessary aggressive treatments.
