# The More You See, the More Confusion: Two Cases of Pneumonia With Confusing Imaging Findings of Adenocarcinoma

## TL;DR

This paper discusses two pneumonia cases that were initially mistaken for lung cancer due to confusing CT scan results, highlighting the need for combining imaging with clinical context.

## Contribution

The paper emphasizes the importance of a multidisciplinary approach in diagnosing lung conditions with ambiguous imaging findings.

## Key findings

- CT scans of pneumonia can resemble lung adenocarcinoma, leading to misdiagnosis.
- A conservative approach in one case led to better outcomes compared to invasive interventions in another.
- Combining clinical context with imaging is crucial for accurate diagnosis.

## Abstract

Imaging studies are a helpful tool when facing pulmonary pathology. While a specific radiologic pattern suggests a diagnosis, a multidisciplinary approach is ideal. Pneumonia and lung adenocarcinoma (LADC) are among the leading causes of morbidity and mortality worldwide. LADC has many patterns on computed tomography (CT); when it manifests as parenchymal consolidation, it is often difficult to distinguish from pneumonia, leading to a delayed or erroneous diagnosis. To achieve a definite diagnosis, clinical information, imaging, and laboratory findings are required. We present two cases that illustrate the importance of applying image interpretation to clinical context. In the first case CT was suspicious for pulmonary malignancy, after a failed response to antibiotics, subsequent invasive interventions led to infection dissemination and complicated clinical course. In the second case, CT showed similar imaging findings to those observed in case one. In case two, however, a conservative approach led to optimal outcomes and improved quality of care.
