SummaryWe report a 26-year-old man with 6 years, history of duodenal gastrointestinal stromal tumor (GIST) with liver, peritoneum and lung metastases. He presented with left eye ptosis, diplopia, left facial numbness and a left temporal fossa mass that was confirmed to be GIST with left skull and left orbit metastases. Craniectomy with cranioplasty, tumor excision and decompression were performed. There was an improvement of his visual symptoms and facial numbness.
