Abstrakt:	Early detection and treatment are critical for improving the prognosis of patients with leptomeningeal metastasis. However, heterogeneous clinical manifestations, non‐specific imaging, and limited sensitivity of cerebrospinal fluid cytology posed challenges to identifying leptomeningeal metastasis in the early stage. Here we reported a case of lung adenocarcinoma complaining of rapid cognitive decline, whose magnetic resonance imaging showed interstitial brain edema. Under the circumstances of negative cerebrospinal fluid cytology, metagenome next‐generation sequencing and copy number variations analysis were applied, which indicated leptomeningeal metastasis and was confirmed in the subsequent cytology.
