A Case of Unknown Pulmonary Nodules

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Diagnostic Imaging

Background:

• Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) is a rare pulmonary condition.
• Accurate diagnosis is crucial for patient management and understanding disease progression.
• Traditional biopsy methods may pose risks, especially for central or difficult-to-reach lesions.

Observation:

• A 54-year-old female with asthma and smoking history presented with incidental pulmonary nodules.
• A dominant left upper lobe nodule, centrally located and near an airway, was identified.
• Robotic-assisted navigational bronchoscopy was employed for biopsy under fluoroscopic guidance.

Findings:

• Histological and immunophenotypic analysis confirmed Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH).
• The case highlights the successful application of advanced bronchoscopic technology.
• The technique proved effective for obtaining diagnostic tissue from a challenging location.

Implications:

• Navigational bronchoscopy offers a safer alternative to percutaneous biopsy for deep or central lung nodules.
• This technology enhances diagnostic capabilities in interventional pulmonology.
• The approach is particularly beneficial for patients with increased risks, such as obesity.
