A 53-year-old male presented with upper abdominal pain of 3 months duration. On clinical examination, a vague lump was palpable in the epigastric region. Contrast-enhanced computed tomography (CECT) of the abdomen revealed a large cystic lesion measuring 8 cm near the tail of the pancreas [Figure 1]. It had an enhancing solid component in the periphery of the cyst [Figure 2]. Upper gastrointestinal endoscopy revealed normal gastric mucosa. A possibility of cystic pancreatic neoplasm was kept and the patient underwent endoscopic ultrasound (EUS). The EUS revealed a heteroechoic lesion arising from the stomach wall with solid and cystic areas [Figure 3]. There were small anechoic areas in the solid component of the lesion suggestive of necrosis [Figure 4]. The lesion could be seen arising from the muscularis propria. EUS-guided fine-needle aspiration (FNA) was performed from the solid component and the cytology revealed features suggestive of a spindle cell tumor [Figure 5]. The patient underwent surgical excision of the tumor and the histopathological examination confirmed the presence of gastrointestinal stromal tumor (GIST). {Figure 1}{Figure 2}{Figure 3}{Figure 4}{Figure 5}

GISTs are mesenchymal tumors, which usually arise from the stomach, small intestine, large intestine, or esophagus. They usually present as solid masses and cystic degeneration of a GIST is very rare. [1],[2] The cystic degeneration is usually seen in larger tumors because of liquefaction and hemorrhage. EUS-FNA may provide an opportunity to obtain the tissue for preoperative diagnosis. [3],[4] EUS findings are variable and may include complex cystic lesions with hyperechoic debris or hypoechoic rounded lesion. [2],[3],[4],[5]
