Primary Lymphoproliferative Lung Diseases: Imaging and Multidisciplinary Approach

Area of Science:

• Pulmonology
• Oncology
• Radiology

Background:

• Lymphoproliferative lung diseases involve primary or secondary lung infiltration.
• Primary pulmonary lymphomas constitute 0.5-1% of lung malignancies.
• Radiological findings are diverse and non-specific, often showing perilymphatic spread.

Purpose of the Study:

• To review the heterogeneous presentation of lymphoproliferative lung diseases.
• To highlight the diagnostic challenges and the role of imaging.
• To discuss the utility of cryobiopsy in diagnosis.

Main Methods:

• Review of radiological findings on High-Resolution Computer Tomography (HRCT).
• Discussion of clinical evaluation and multidisciplinary approaches.
• Evaluation of cryobiopsy as a diagnostic tool.

Main Results:

• Common HRCT findings include consolidations, masses, nodules, ground-glass opacities, and interstitial involvement.
• Ancillary signs like halo sign or air bronchogram may aid differential diagnosis.
• Cryobiopsy provides larger, artifact-free tissue samples compared to surgical biopsy.

Conclusions:

• Accurate diagnosis of lymphoproliferative lung diseases necessitates a multidisciplinary approach.
• While HRCT is crucial, tissue diagnosis is definitive.
• Cryobiopsy is a promising, minimally invasive technique for obtaining diagnostic tissue samples.
