Intimal sarcoma of blood vessels is a rare, aggressive tumor originating from vascular endothelial cells. This report presents a 22-year-old male diagnosed with an intimal sarcoma of the lower pulmonary vein, detailing diagnosis, treatment, and prognosis information. Additionally, this report explores the application application of Endobronchial Ultrasound-Guided Fine-Needle Aspiration (EBUS-FNA) alongside with Rapid Remote Online Evaluation (ROLE) for identifying a mass-like lesion in the pulmonary vein.

Use of Narrow Band Imaging to Guide Endobronchial Biopsy for Suspected Sarcoidosis.

J Bronchology Interv Pulmonol

April 2025

Department of Medicine, Division of Respirology, University of Calgary, Calgary, AB.

Background: Diagnosis of sarcoidosis often involves endobronchial biopsy (EBB), but studies have shown varying yields for EBB in suspected sarcoidosis, partly due to differences in identifying abnormal mucosa under white light (WL). Narrow band imaging (NBI) may assist in the visualization of abnormal mucosa, but its role in sarcoidosis remains to be characterized.

Methods: Individuals referred for suspected sarcoidosis were considered for enrollment.

Sarcoidosis is a systemic granulomatous disease of unknown etiology, primarily affecting the lungs and the lymphatic system. Its diagnosis is challenging, and in many cases, it requires histopathological confirmation through the identification of non-caseating granulomas. The presented case illustrates its diagnostic complexity and highlights a rare, delayed complication associated with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).

Background And Objective: Diagnosis of pathology in the mediastinum has proven quite challenging, given the wide variability of both benign and malignant diseases that affect a diverse array of structures. This complexity has led to the development of many different non-invasive and invasive diagnostic modalities. Historically, diagnosis of the mediastinum has relied on different imaging modalities such as chest X-ray, computed tomography (CT), magnetic resonance imaging, and positron emission topography.

Background And Objective: Transesophageal endosonography, including endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA), has been applied to the diagnosis of benign as well as malignant diseases. This narrative review summarizes the recent use of EUS-(B)-FNA in diagnosing sarcoidosis.

Methods: A comprehensive and systematic online literature search of PubMed was conducted using the keywords ("sarcoidosis"), and ("EUS" OR "EUS-FNA" OR "EUS-B" OR "EUS-B-FNA" OR "endoscopic ultrasound guided fine needle aspiration" OR "endoscopic ultrasound using the EBUS scope guided fine needle aspiration" OR "endoscopic ultrasound using the EBUS bronchoscope" OR "transesophageal" OR "transesophageal endoscopic ultrasound guided fine needle aspiration" OR "transesophageal bronchoscopic ultrasound guided fine needle aspiration").
