OBJECTIVE. The aim of this study was to present the spectrum of clinic
al and radiologic manifestations of carcinomas that originate within h
iatal hernias, to emphasize their increasing prevalence among the elde
rly patient population, and to assess the reasons for radiologic misdi
agnosis. MATERIALS AND METHODS. Medical records and radiologic studies
of 27 adult patients (15 men and 12 women; 54-83 years old [mean, 71
years old]) with surgically proven adenocarcinomas in the herniated pr
oximal part of the stomach were reviewed. RESULTS. A hiatal hernia wit
h intrinsic abnormalities suggestive of carcinoma was shown by upper g
astrointestinal tract examination obtained before surgery in all 27 pa
tients, A diagnosis of malignancy was reported at the time of examinat
ion for 24 patients (89%); for the remaining three patients, diagnosis
was made by endoscopy. The predominant feature, seen in 15 patients (
56%), was an infiltrative process that caused deformity and rigidity o
f the hiatal hernia in conjunction with thickened, nodular mucosa, The
intrahernial tumor appeared as a well-demarcated sessile polyp or lob
ulated mass in nine patients (33%) and as ulcerations and eccentric wa
ll thickening in three patients (11%), All errors were perceptive in n
ature, On review, we saw minimal evidence of infiltration or small pol
ypoid masses. CONCLUSION. Although some of the radiologic abnormalitie
s were minimal, our review of 27 cases in a biphasic upper gastrointes
tinal tract series resulted in detectable radiographic findings of car
cinomas associated with hiatal hernias for all cases, Meticulous asses
sment of the herniated fundus and gastroesophageal regions is crucial
for the detection of such tumors.
