Cauda equine syndrome (CES) is a neurological situation brought on by compression of the cauda equine. Right here, we show a case of CES as the first symptom of leptomeningeal metastases from non-small cell lung carcinoma with out mind metastases. A 59-year-old male suffered progressive decrease extremity motor dysfunction, urinary dysfunction, and decrease extremity sensory dysfunction. He was clinically identified with CES. Nuclear magnetic resonance imaging demonstrated a number of imprecise nodules within the space of conus medullaris and cauda equine, with out lumbar or thoracic herniated discs. The serum carcinoembryonic antigen focus was 191.20 ng/mL. The conclusion following positron emission tomography-computed tomography was a proper higher lung malignant tumor with mediastinal lymph node metastasis and cauda equina metastasis. Pathologic prognosis was of main adenocarcinoma of the lung by bronchoscopic biopsy. EML4-ALK fusion and EGFR mutations had been absent, and thus the affected person acquired chemotherapy. Nonetheless, signs of intracranial hypertension arose 1 month later, and the affected person died three months postadmission. Rising CES could also be an indication of metastasis of a malignant tumor, presenting a particularly difficult situation, particularly for sufferers with lung most cancers. Positron emission tomography-computed tomography is a reasonably efficient method to make the prognosis.
