Gastrointestinal Stromal Tumor With a Rare Associated Meningioma: A Case Report

Gastrointestinal stromal tumors (GISTs) tend to be associated with other tumors. In certain familial cancer syndromes, GIST has been associated with breast cancer or other endocrine tumors. Multiple endocrine neoplasia syndrome along with certain other genomic mutations such as succinate dehydrogenase complex mutations described GIST as one of the potential tumors of the syndrome. There has not yet been a definite association between GIST and meningioma. We present a case of a patient with a GIST who was later found to have a meningioma on incidental brain imaging. Despite being a benign tumor not requiring additional intervention, it is quite apparent that providers need to have a low threshold to scan for other tumors if suspicious symptoms arise.
