Brunner's gland hyperplasia is a
tumor arising from the
Brunner's gland and the lesions account for 10.6% of benign duodenal
tumors. These lesions are usually asymptomatic and detected incidentally by
endoscopy or by a UGI
barium study. In the case of severe and atypical forms, these lesions cause
bleeding,
intestinal obstruction or intussuception. However,
Brunner's gland hyperplasia causing an annular duodenal
stricture and subsequent
intestinal obstruction has been rarely reported. We
report here a very rare case of
Brunner's gland hyperplasia presenting as an annular
stricture and obstruction.
