Unusual presentation of gastrointestinal stromal tumor with early cerebral involvement

Gastrointestinal stromal tumor (GIST) is a rare tumor typically arising from gastrointestinal tract. GIST very rarely metastasizes beyond abdominal cavity. Metastatic spread to the brain is anecdotal. This is a case study describing metastatic GIST with early cerebral involvement and resistance to therapy with KIT tyrosine kinase inhibitor imatinib mesylate.
