A 26‐year‐old female with no significant past medical history
presented with non‐specific abdominal discomfort, which
had demonstrated a partial response to a trial of proton pump
inhibitor (PPI) therapy. A gastroscopy was performed which
showed a small (5‐6 mm in diameter) diverticulum in the an-
trum (Figure 1A,B).
Gastric diverticula are very rare with a reported preva-
lence of 0.01%‐0.11% at upper gastrointestinal endoscopy
and 0.03%‐0.3% at autopsy studies.1 The majority (75%) of
true gastric diverticula are located in the fundus, while in ex-
tremely rare cases they have been reported in the antrum.2
False diverticula (pseudodiverticula) are less common and
typically associated with other gastrointestinal disorders,
such as peptic ulcer disease or malignancy.1 Most cases are
asymptomatic, but symptomatic patients can present with a
variety of clinical manifestations, such as abdominal pain,

Key Clinical Message
Gastric diverticula are rare and may sometimes cause diagnostic confusion. Most
cases are asymptomatic and diagnosed incidentally. However, sometimes they can
cause a variety of clinical manifestations and may be complicated by bleeding, per-
foration, or malignancy. Therefore, clinicians should be aware of this unusual find-
ing and the available management options.

nausea, vomiting, dyspepsia, weight loss, bleeding, or even
perforation. The mechanisms by which gastric diverticula
can cause symptomatology are somewhat unclear but include
development of complications and food retention with bacte-
rial overgrowth (which can lead to dyspepsia, belching, and
halitosis).
Management of symptomatic patients is usually conser-
vative with PPI therapy, but in cases of gastric diverticula
complicated by bleeding, perforation, or malignancy, surgery
(open or laparoscopic resection) is recommended.
