# Point of Care Ultrasound Identification and Aspiration of a Neck Lymph Node

## TL;DR

This paper describes a case where point-of-care ultrasound was used to diagnose and aspirate a neck lymph node in a patient with lung cancer.

## Contribution

The novelty lies in using real-time ultrasound-guided fine needle aspiration for tissue diagnosis in this clinical context.

## Key findings

- Real-time ultrasound-guided fine needle aspiration successfully diagnosed recurrent lung adenocarcinoma.
- The method provided a minimally invasive and effective tissue diagnosis for staging lung cancer.
- Ultrasound-guided aspiration of neck lymph nodes can be a viable diagnostic option.

## Abstract

The tissue diagnosis and staging of all types of lung cancer is foundational for prognosis and establishing the optimal treatment plan. In order to appropriately stage lung cancer, the highest stage should be established using the 8th edition TNM criteria, where tumor size (T), nodal involvement (N), and metastasis (M) are all taken into account. Establishing a tissue diagnosis may involve the use of CT guided biopsy, navigational bronchoscopy, endobronchial biopsy, EBUS, percutaneous lymph node biopsy and/or excisional biopsy of supraclavicular nodes. It is recommended to proceed with the method that is considered least invasive and provides the highest staging. We present a case of recurrent lung adenocarcinoma diagnosed with real time ultrasound-guided fine needle aspiration of a neck lymph node.
