What are the imaging features of malignant gastric ulcers?
Malignant gastric ulcer generally refers to gastric cancer in peptic ulcers. When imaging is performed, it usually has features such as irregular morphology and blurred edges.
1. X-ray barium swallow imaging
1. Irregular morphology: due to the rapid growth of tumor cells, a large mass will form in a short period of time, resulting in uneven stomach wall, and it will also be accompanied by the expansion of the ulcer surface and the infiltration of surrounding tissues.
2. Blurred edges: If the patient's condition is more serious, the gastric mucosa may be seriously damaged, resulting in local necrosis, which will lead to unclear boundaries and obvious boundaries with the surrounding normal tissues.
2. CT examination
For patients with early-stage gastric cancer, abdominal CT scan can detect a hypodense area in the stomach, which is accompanied by abdominal lymph node metastasis. As the disease progresses, ascites, liver enlargement and other conditions may also occur.
3. Endoscopic ultrasound
When the patient undergoes endoscopic ultrasound, the gastric wall is thickened, the gastric cavity is narrowed or deformed, the gastric wall is stiff, peristalsis is weakened or even disappears, and the tumor invades the perigastric organs, such as hepatic portal vein compression and obstruction, pancreatic atrophy, and mesenteric vasodilation.
4. Magnetic resonance imaging
When the patient undergoes MRI, the limited enhancement of the gastric wall can be seen, which is manifested as "target ring sign" and "map sign", and can also show structural changes in the external invasion of the gastric wall and adjacent organs.
Patients are advised to seek medical treatment in a timely manner to avoid delaying the condition. In daily life, we should pay attention to a reasonable diet and avoid eating spicy and stimulating foods, such as chili peppers and peppers. At the same time, you should also pay attention to rest, ensure enough sleep time, and avoid staying up late.
