Schwannomas of gastrointestinal tract are very rare mesenchymal tumors. They constitutes about 0.2% of abdominal tumors and are originating from Schwann cells. These types of tumors presents generally very slow growing mass, which is mostly benign. The treatment of choice is surgical resection with wide resection margins. In our case report an MRI was performed in a 60-year-old female patient by non-specific back pain. To the other findings belong also a gastric abdominal tumor and a mass in retroperitoneum at the side of the right iliac vein. A surgical intervention was recommended. The patient underwent a Wedge-resection of the gastric tumor and excision of the mass in retroperitoneum through a midline lower abdominal laparotomy. The histopathologically and immunohistochemically corresponded both tumors to a schwannoma. There is no reccurence with follow up of 2 year.
