Key result
Bronchoscopy with biopsy identified HER2-positive breast carcinoma with metastatic lymphangitic spread in 1 patient whose CT findings mimicked interstitial lung disease.
Why the study?
Pulmonary lymphangitic carcinomatosis radiologic findings may mimic alternative pulmonary pathology such as interstitial lung disease or infection, leading to delayed diagnosis.
Population
A middle-aged female with metastatic breast cancer

Biopsy should be considered for CT mimicking ILD in cancer patients; this case leaves open the true incidence of lymphangitic carcinomatosis.
Case Report (n=1)
CT findings of Pulmonary Lymphangitic Carcinomatosis can mimic interstitial lung disease, highlighting the importance of early tissue biopsy for definitive diagnosis.
GALBREATH et al. (2025) conducted a case report in Pulmonary Lymphangitic Carcinomatosis (n=1). Bronchoscopy with biopsy was evaluated. Bronchoscopy with biopsy identified HER2-positive breast carcinoma with metastatic lymphangitic spread in 1 patient whose CT findings mimicked interstitial lung disease.
