The occurrence of bone metastases (BM) in gastric cancer without prior gastrointestinal (GI) symptoms is a rare phenomenon that has been sporadically documented in the existing literature. We report a case of a 27-year-old male presenting with chief complaints of severe backache for one month. After an upper gastrointestinal endoscopy and biopsy, the primary source of cancer was identified as a solitary gastric adenocarcinoma, supporting the diagnosis of bony metastases on the magnetic resonance imaging (MRI) of the spine. The patient was planned to start on palliative chemotherapy (5-fluorouracil, leucovorin, oxaliplatin, and docetaxel {FLOT} regimen) with palliative radiotherapy of 20 Gy in five fractions to bony metastasis. The patient denied treatment and was discharged against medical advice.
