Eosinophilic
gastroenteritis is an unusual
disease that is associated with various clinical gastrointestinal manifestations. Its severity depends on the area involved as well as the wall layer involved. Eosinophilic
gastroenteritis often causes
abdominal pain,
nausea,
vomiting and
diarrhea. To date, there has been an extremely rare case of eosinophilic
gastroenteritis with systemic symptoms, such as
fever or
lymphadenopathy (LAP). We experienced a case of a 68-year-old-
woman with
fever and
abdominal pain. Abdominal computed
tomography revealed diffuse wall thickening of the
gastric antrum as
linitis plastica. Multiple hot uptakes of
lymph nodes were visualized on fludeoxyglucose-
positron emission tomography. The gastric
biopsy pathological
report demonstrated eosinophilic infiltration without malignant
cells. We could not exclude
malignancy and performed an exploratory
laparoscopy. A
lymph node specimen showed reactive
hyperplasia, and her illness was finally diagnosed as eosinophilic
gastroenteritis. Herein, we
report the case with a brief
review.
