a, c A 9-year-old girl was admitted to the pediatric emergency department with complaints of black stool and fatigue. She had several admissions to various gastroenterology departments during the last 2 years due to recurrent melena and fatigue. In the laboratory tests; Hb was 7.8 gr/dL (normal range 11.7–15.5 gr/dL) and ferritin was 8.3 ng/mL (normal range 20–336 ng/mL). Meckel’s diverticulum scintigraphy was normal. Esophagogastroduodenoscopy and ileocolonoscopy showed a normal appearing mucosa. Abdominal US was normal. a Axial T2-weighted MRI shows heterogeneous mass with intratumoral cystic portion at proximal jejunum (arrows). b Diffusion-weighted image (b = 800 s/mm2) and (c) apparent diffusion coefficient (ADC) map show diffusion restriction of solid portion of the tumor (arrows). Segmental resection was performed and the histopathological diagnosis was jejunal gastrointestinal stromal tumor
