A case report of left paraduodenal hernia with a spontaneous reduction on follow-up: the rare demonstration on computed tomography

Abstract

Background Left paraduodenal hernia (PDH) makes for around 40% of all internal hernias. It is due to the prolapse of bowel through fossa of Landzert, an anatomic variant that is found in around 2% of the population. This hernia is presumed to be spontaneously reducible in many patients with recurrent symptoms. Case presentation The present report shows the case of this condition in a 65-year-old male presenting with recurrent abdominal pain and subacute intestinal obstruction who was unwilling for surgery and was managed conservatively. A follow-up scan after 11 months revealed complete spontaneous resolution of hernia. Conclusions This represents only the second demonstration of the oft-mentioned spontaneous reduction of this condition on computed tomography. The radiologists should be aware of this uncommon entity and in the event of clinical suspicion; the imaging should be performed when the patient is symptomatic.

A Case Report on Internal Hernia as an Unusual Cause of Small Bowel Obstruction: A Diagnostic Triumph Unveiled by Computed Tomography Scan

“…Internal hernias, although uncommon, are a well-recognized cause of intestinal obstruction. The most prevalent type, constituting approximately 53% of cases, is the PDH, which exists in two forms: right-sided PDH and left-sided PDH [ 6 ]. The mesentericoparietal fossa of Waldeyer is the aperture on the right, while the fossa of Landzert is located on the left, which accounts for three times as many cases [ 7 ].…”

A late presentation of a left paraduodenal hernia in an elderly patient admitted in emergency: A case report

“…However, when Gastrographin is not able to transit and in cases in which it is not effective, surgical intervention is recommended within 72 hours [20] . MDCT makes it possible to incidentally detect asymptomatic PDHs and in some cases PDHs could reduce spontaneously [21] .…”

Fatal Bowel Obstruction Due to Paraduodenal Hernia: A Case Report

“…5 Computed Tomography is the more relied upon radiologic method for these hernias. 8 CT may show cluster of small bowel loops behind the mesenteric vessels. 8,9 Patients are treated via surgical intervention whether the patient is asymptomatic or symptomatic as the risk for bowel obstruction or strangulation is very high in untreated hernias.…”

“…8 CT may show cluster of small bowel loops behind the mesenteric vessels. 8,9 Patients are treated via surgical intervention whether the patient is asymptomatic or symptomatic as the risk for bowel obstruction or strangulation is very high in untreated hernias. Open surgery and laparoscopic approaches have been used to treat these hernias.…”
