# Paraneoplastic Cerebellar Degeneration Revealing Non-Small Cell Lung Cancer: A Case Report

## TL;DR

A case report shows how a neurological condition revealed an underlying lung cancer in a 61-year-old patient.

## Contribution

This case highlights the importance of early diagnosis of paraneoplastic cerebellar degeneration to improve cancer detection and outcomes.

## Key findings

- Subacute cerebellar degeneration led to the discovery of non-small cell lung cancer in a 61-year-old patient.
- Early detection of paraneoplastic neurologic symptoms can improve both neurological and oncological outcomes.
- Paraneoplastic cerebellar degeneration is a rare but significant subset of paraneoplastic neurologic degeneration.

## Abstract

Paraneoplastic neurologic degeneration (PND) manifests as a sudden or subacute neurological syndrome often linked to underlying cancer, either overt or subclinical. Within the spectrum of PND, subacute paraneoplastic cerebellar degeneration (PCD) represents a distinctive subset. While rare, prompt diagnosis holds the potential to ameliorate both neurological and oncological outcomes. Herein, we present the case of a 61-year-old patient diagnosed with subacute cerebellar degeneration, ultimately unveiling non-small cell lung carcinoma.
