# Typical CT Pattern in Rheumatoid Arthritis: Exuberant Honeycombing

## TL;DR

Exuberant honeycombing on CT scans helps distinguish connective tissue disease-related lung disease from idiopathic pulmonary fibrosis.

## Contribution

The study identifies exuberant honeycombing as a specific CT pattern linked to connective tissue disease-associated interstitial lung disease.

## Key findings

- Exuberant honeycombing is specific to connective tissue disease-associated interstitial lung disease.
- This pattern helps differentiate from idiopathic pulmonary fibrosis.
- It is associated with usual interstitial pneumonia pattern.

## Abstract

Teaching point: Exuberant honeycombing on high-resolution computed tomography of the chest is a specific sign of connective tissue disease-associated interstitial lung disease with a usual interstitial pneumonia pattern and contributes to differentiate it from idiopathic pulmonary fibrosis.
