A 46-year-old male presented with progressive paraparesis and sensory impairment in both lower limbs since 2 months. He had urinary and bowel incontinence. On examination he had flaccid paraplegia with a sensory level at 11(th) dorsal vertebral level. Magnetic resonance imaging (MRI) scans of the lumbosacral spine showed an enhancing intramedullary lesion in the conus. The patient underwent excision of the conus mass. Histopathology confirmed the tumor to represent a poorly differentiated metastatic carcinoma from an unknown primary. A positron emission tomography-computed tomography (PET-CT) scan of the whole body revealed hypermetabolic activity in the hilum of the right lung confirmed to be a lung carcinoma on a CT-guided biopsy. The patient was undergoing chemoradiation at 1 month follow-up. The author's literature search has yielded only four other case reports of conus metastasis of which only one is in English literature. The present case report and review of literature are presented.
