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

## TL;DR

A rare case of gastric body tuberculosis was diagnosed through regular CT scans and endoscopic ultrasound-guided biopsy in a patient with abdominal tuberculosis.

## Contribution

Highlights the importance of regular CT follow-up and EUS-FNA in diagnosing secondary gastric tuberculosis.

## Key findings

- Gastric body tuberculosis can develop from existing abdominal tuberculosis and be missed if not monitored closely.
- EUS-FNA confirmed the diagnosis after CT scans showed a gastric wall mass.
- Combining gastroscopy with EUS-FNA improves early detection of gastric tuberculosis.

## Abstract

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

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.

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.
