Patient History

Consecutive sampling of the lesion (biopsy during bronchoscopy) resulted in diagnosis of squamous cell lung cancer. Referral to lung clinic for assessment of N-stage prior surgery.
CT
Enlarged lymph node in station 7 (fig. 1).
Enlarged lymph node in station 4L (fig. 2).
Endobronchial ultrasound
EBUS-TBNA confirms enlarged lymph nodes in station 7 and 4L. Both stations were sampled. LN7 above the left atrium and right pulmonary artery (fig. 3).

Enhanced ultrasound view for flow detection (eFlow).
Here flow is highlighted in the upper margin of the left atrium and within a microvessel in subcarinal lymph node station 7 (fig. 4).

Histology
Squamous cell carcinoma (SCC) of the right lower lobe with confirmed lymph node metastasis in LN7 and LN4L.
N3 disease.
