# Pulmonary amyloidosis: a case report

## TL;DR

This paper presents a rare case of a 60-year-old woman diagnosed with pulmonary amyloidosis after experiencing breathing difficulties and a lung nodule was found.

## Contribution

The novelty lies in reporting a rare case of pulmonary amyloidosis with a clear diagnostic process and follow-up.

## Key findings

- A 60-year-old woman with a history of pleural tuberculosis was diagnosed with pulmonary amyloidosis.
- CT-guided biopsy confirmed the diagnosis of pulmonary amyloidosis.
- The patient's follow-up has been unremarkable.

## Abstract

Amyloidosis is a rare disease in which abnormally folded proteins form accumulations called amyloid fibrils that accumulate in different tissues and organs, sometimes leading to organ dysfunction, organ failure and death. Rarely, pulmonary involvement can take one of three forms: nodular, diffuse alveolar-septal, or tracheobronchial. We report the case of a 60-year-old woman previously treated for confirmed pleural tuberculosis. She was admitted with progressive dyspnea for three months and a chest CT scan revealed a pulmonary nodule in the middle lobe. She underwent CT-guided biopsy and diagnosis of pulmonary amyloidosis was retained by histology. Follow up has been unremarkable.
