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.
