Intramural gastric abscess
Background:
Fever and abdominal pain are common symptoms with many possible differential diagnoses.
Case Presentation:
An otherwise healthy man in his twenties was admitted to hospital with fever and epigastric pain. On admission he was febrile. The physical examination revealed nothing abnormal except epigastric tenderness. Laboratory data showed elevated white blood cell count and C-reactive protein level. Abdominal CT scan demonstrated a large mass in the gastric antrum. The patient underwent upper endoscopy revealing a submucosal tumour-like expansion. Puncture of the mass resulted in drainage of pus, and biopsies additionally confirmed the diagnosis of gastric wall abscess. Follow-up scans eight weeks after drainage showed complete resolution.
Interpretation:
Gastric wall abscess is a rare but important differential diagnosis in patients presenting with fever and abdominal pain. As shown, the condition can also occur in younger patients without any known risk factors.

01:23Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
