Gastrointestinal stromal tumors (GISTs) are the most common gastrointestinal mesenchymal tumors. Computed tomography (CT) often shows exophytic gastrointestinal masses with cystic changes, necrosis or fistula formation, and heterogeneous enhancement. After Gleevec therapy, the primary tumor, its metastases, and its recurrences can develop cystic changes and decrease in size, these findings can be satisfactorily monitored by CT. We report on 42 patients with proven GISTs, five presenting with metastases and nine patients with recurrence or development of metastases after surgery and chemotherapy.

Anti-vascular endothelial growth factor-associated thrombotic microangiopathy (aVEGF-TMA) was recently discovered in patients with malignant tumors. Four aVEGF-TMA patients diagnosed by renal biopsy between 2018 and 2022 were identified, and all were females aged 30-62 years (mean age, 47 years). Two patients with malignant gastrointestinal stromal tumors who received sunitinib were analyzed.

Gastric schwannoma is a relatively rare submucosal mesenchymal tumor with low probability of metastasis and arises from Schwann cells of the gastrointestinal nervous plexus. Surgical therapy is the main treatment of gastric schwannoma with symptoms or malignant tendency. Gastroparesis is a potential complication following gastrointestinal surgery, which is a clinical syndrome caused by gastric emptying disorder and characterized by nausea, vomiting, and bloating, resulting in insufficient nutrient intake.
