Gastrosplenic fistula is a rare clinical condition that occurs mostly in association with splenic or gastric lymphomas [1]. We report a case of a gastrosplenic fistula that formed secondary to a diffuse large B-cell splenic lymphoma and presented as upper gastrointestinal bleeding with hematemesis.

A 68-year-old man was admitted to our hospital due to hematemesis. Endoscopy revealed a large cavitary lesion with necrotic material at the posterior gastric fundus ([Fig. 1]), and histological examination of biopsy specimens taken from the cavity showed diffuse large B-cell non-Hodgkin’s lymphoma ([Fig. 2]). Computed tomography (CT) revealed a large splenic mass with a fistulous tract between the gastric lumen and an air-filled necrotic splenic cavity ([Fig. 3]). Surgical treatment with en bloc resection was preferred as initial treatment rather than chemotherapy, to avoid the risk of recurrence of bleeding. Chemotherapy was started 30 days postoperatively. The patient continues to remain under evaluation.

In cases of splenic lymphoma, close proximity of the gastric fundus to the spleen and the presence of the gastrosplenic ligament facilitate the union of these organs and the formation of a fistula as a result of growth and spread of the tumor cells, as well as tumor necrosis or infection. The gastrosplenic fistula may occur either spontaneously or secondary to chemo- or radiation therapy, with the possibility of massive hematemesis secondary to erosion of the splenic vessels by the gastric contents [2] [3]. Endoscopy usually aids direct visualization of the fistulous tract opening, which is seen as a cavitary lesion, and abdominal CT provides the definite diagnosis. Although there are reports of gastrosplenic fistula resolving with chemotherapy, early radical surgical resection seems to be the best initial treatment approach to avoid re-bleeding. Gastrosplenic fistula should be suspected in patients with splenic lymphoma and upper gastrointestinal bleeding. Definitive surgical treatment is warranted in such cases to avoid massive gastrointestinal bleeding [4] [5].
