# Necrotizing Pneumonia Mimicking Lung Tumour: A Case Report

## TL;DR

A case of necrotizing pneumonia mistaken for lung cancer shows the need for early diagnosis and multidisciplinary care to avoid misdiagnosis and improve outcomes.

## Contribution

This case emphasizes the diagnostic challenges of necrotizing pneumonia and the value of a multidisciplinary approach in preventing misdiagnosis.

## Key findings

- Necrotizing pneumonia can mimic lung cancer on imaging, leading to initial misdiagnosis.
- Contrast-enhanced CT scans and biopsies helped confirm the correct diagnosis.
- Antibiotic treatment led to significant improvement, highlighting the importance of timely intervention.

## Abstract

Necrotizing pneumonia, a rare but severe complication of community‐acquired pneumonia, can mimic lung tumours. This case report highlights the importance of early diagnosis using contrast‐enhanced chest CT scans and a multidisciplinary approach to prevent misdiagnosis that can increase morbidity and mortality. A 57‐year‐old male presented with severe respiratory symptoms, including haemoptysis and weight loss. The patient was initially misdiagnosed with lung cancer due to a necrotic mass based on imaging. Subsequent biopsies revealed no signs of malignancy. A multidisciplinary team concluded that the findings suggested necrotizing pneumonia rather than a lung tumour. The patient was successfully treated with antibiotics, leading to significant improvement. This case highlighted the importance of accurate and timely diagnosis in managing necrotizing pneumonia, particularly when it mimics malignancy. Early recognition, supported by appropriate diagnostic tools and targeted antibiotic therapy, is crucial for appropriate management of necrotizing pneumonia and achieving positive outcomes. A multidisciplinary approach is essential to ensure comprehensive care, prevent misdiagnosis and avoid unnecessary treatments. Prompt and precise intervention can significantly enhance patient prognosis and reduce the risk of complications associated with necrotizing pneumonia.

This case report describes a male patient with necrotizing pneumonia mimicking a lung tumour and highlights the importance of accurate and timely diagnosis in managing necrotizing pneumonia, particularly when it mimics malignancy.
