Acute gastritis
Updates to Article Attributes
Body
was changed:
Acute gastritis is a broad term that encompasses a myriad of causes of gastric mucosal inflammation.
Epidemiology
Depends on the aetiology (see below).
Clinical presentation
- asymptomatic
- epigastric pain/tenderness
- nausea and vomiting
- loss of appetite
Pathology
Aetiology
- infection: H. pylori (most common)
- systemic illness: trauma and burns
- pharmacological/medication:
NSAIDSNSAIDs - autoimmune
- caustic ingestion
- acid/alkali ingestion
- immunosuppression/AIDS-related
- cytomegalovirus
-
candidaCandida albicans - histoplasmosis
- cryptosporidiosis
- toxoplasmosis
- eosinophilic gastritis
Radiographic features
CT
CT findings can suggest gastritis and detect complications such as gastric perforation, however, often gastritis and tumours cannot be easily differentiated on CT. Moreover, causes of gastritis cannot be determined on CT. Both circumstances require clinical/lab correlation, probable endoscopy examination and tissue biopsy 1-2,2.
CT findings suggestive of gastritis include:
- gastric wall oedema: measuring the HU may be useful to differentiate oedema from low attenuation neoplastic lesion
- halo sign: mucosal enhancement surrounded by submucosal and gastric wall oedema
