Splenosis simulating an intramural gastric mass.

Area of Science:

• Gastroenterology
• Surgical Pathology
• Diagnostic Imaging

Background:

• Splenosis is the autotransplantation of splenic tissue after splenic capsule injury.
• It can occur following splenectomy due to trauma or iatrogenic causes.
• Splenosis can present as a mass lesion, sometimes mimicking other pathologies.

Purpose of the Study:

• To present a case of splenosis simulating a gastric mass.
• To emphasize the diagnostic considerations of splenosis in patients with a history of splenectomy.

Main Methods:

• Case report presentation.
• Review of clinical presentation, imaging findings, and histopathological examination.

Main Results:

• A patient with a history of splenectomy presented with a fundal intramural gastric mass.
• The lesion was diagnosed as splenosis, which mimicked a leiomyoblastoma.
• The absence of the spleen was a key factor in considering splenosis.

Conclusions:

• Splenosis should be included in the differential diagnosis of intramural or exogastric lesions.
• A history of splenectomy is crucial for considering splenosis as a diagnostic possibility.
• Radiological and pathological evaluation is essential for accurate diagnosis.
