Case Report: Rare case of secondary gastric body tuberculosis-diagnostic challenges arising from the insidious spread of abdominal tuberculosis.

BACKGROUND

Gastric body tuberculosis is extremely rare and easy to be missed or misdiagnosed.

CASE PRESENTATION: A 62-year-old female with tuberculous peritonitis was receiving formal antituberculosis treatment, the peritoneal and perihepatic nodules were absorbing during her regular follow-up, but contrast-enhanced CT scan of the abdomen revealed a solid mass on the anterior gastric wall that had penetrated the gastric wall, review her previous enhanced CT scans, we found the gradual extension of an abdominal tuberculous lesion into the gastric wall, which was almost ignored. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed, and finally confirmed by pathology as gastric body tuberculosis.

CONCLUSION

For patients with perigastric tuberculous lesions, regular follow-up with CT scan is crucial. When necessary, combining gastroscopy with EUS-FNA can help establish an early diagnosis.
