Gastrointestinal sarcoidosis is rare, but CT scans increasingly identify liver, spleen, and lymph node involvement. Gastric sarcoidosis, often linked to lung disease, presents variably on imaging, sometimes mimicking other conditions.

Area of Science:

  • Gastroenterology
  • Radiology
  • Pathology

Background:

  • Sarcoidosis is a multisystem inflammatory disease of unknown etiology.
  • Gastrointestinal involvement is an uncommon manifestation of sarcoidosis.
  • Computed tomography (CT) aids in recognizing extrathoracic sarcoidosis, including hepatic, splenic, and adenopathic disease.

Observation:

  • Gastric sarcoidosis, though rare, is the most frequent gastrointestinal site affected.
  • Radiologic appearances of gastric sarcoidosis are highly variable.
  • Diagnosis can be challenging, with positive biopsies sometimes obtained from radiologically normal stomachs.

Findings:

  • Gastric sarcoidosis can manifest as ulcerations mimicking peptic ulcer disease.
  • Mucosal changes range from minor nodularity to significant enlargement, potentially resembling Menetrier disease.

  • In severe cases, gastric sarcoidosis can present as a linitis plastica pattern, mimicking scirrhous carcinoma.

    • Implications:

    • Increased awareness of variable gastric sarcoidosis presentations is crucial for accurate diagnosis.
    • Radiologists and gastroenterologists should consider sarcoidosis in the differential diagnosis of diverse gastric pathologies.
    • Early recognition and diagnosis of gastrointestinal sarcoidosis can guide appropriate management and improve patient outcomes.
