Chilaiditi Syndrome in Two Cases Presented with Respiratory Distress Symptoms

A Rare Presentation of Pseudo-Pneumoperitoneum Secondary to Chilaiditi Sign and Chilaiditi Syndrome in Two Pre-adolescent Females: A Case Series

Chilaiditi sign is defined as the interposition of the colon or small intestine between the liver and the right diaphragm in the absence of symptoms. Chilaiditi syndrome refers to the condition where the Chilaiditi sign is associated with symptoms including abdominal pain. In this series, we present the cases of two pre-pubescent patients with these rare conditions.  A 10-year-old female with a history of autism, IgA deficiency, and constipation presented for gastrointestinal studies due to weight loss and constipation. An abdominal X-ray revealed bowel gas under the right hemidiaphragm and colonic interposition between the diaphragm and the liver, raising concerns for the Chilaiditi sign. She underwent a bowel cleanout, with studies revealing colonic dysmotility and compartmentalization of the sigmoid colon and rectum with the absence of coloanal reflex. A nine-year-old female with a history of constipation, developmental delay, and hypotonia presented with abdominal pain, vomiting, constipation, and decreased appetite. She also manifested tachypnea, abdominal distension, and abdominal tenderness, with an abdominal X-ray revealing a dilated colon interposed between the liver and diaphragm, confirming Chilaiditi syndrome. Prior gastrointestinal studies showed dilated and redundant sigmoid colon and dyssynergia. The treatment entailed rectal irrigations and catheter decompression, which led to the improvement of symptoms. Conservative treatment is the treatment of choice for patients with Chilaiditi sign or Chilaiditi syndrome. It is important to distinguish Chilaiditi syndrome, a common cause of pseudo-pneumoperitoneum, from true pneumoperitoneum, as this diagnosis warrants immediate surgical intervention. Surgical treatment is indicated when there are signs of bowel obstruction or ischemia and for cases with recurrent Chilaiditi syndrome. Raising awareness about this condition is important to reduce the incidence of misdiagnosed surgical emergencies and resulting exploratory surgeries, as well as to avoid high-risk colonoscopies. Chilaiditi sign and Chilaiditi syndrome are relatively uncommon entities, and their prevalence is very rare in the pediatric population. Hence, we believe this case series will contribute to providing clinical awareness of these major complications and avoiding invasive interventions due to the inaccurate diagnosis of these conditions as pneumoperitoneum.

A Case Report of Chilaiditi's Syndrome With Sigmoid Volvulus

Chilaiditi's syndrome is the hepatodiaphragmatic interposition of the colon. It can be caused by any pathology of intestinal, hepatic, and diaphragmatic factors. Any anatomic variations or functional abnormalities can increase the development of Chilaiditi's syndrome. It is usually asymptomatic and is found indecently in radiological studies. It is treated conservatively as long as any complications do not arise. This case of Chilaiditi's syndrome was associated with sigmoid volvulus and multiple tubercles on its surface. A 35-year-old male patient presented to the outpatient department (OPD) with complaints of weight loss, bilateral flank pain, abdominal distention, decreased appetite, vomiting, and diarrhea. CT scan showed a grossly distended loop of the colon with sigmoid volvulus and Chilaiditi's sign. A laparotomy was done, sigmoid volvulus was relieved, a biopsy of tubercles was taken for histopathology, and a colostomy was done. The biopsy result showed abdominal tuberculosis. The colostomy was later reversed. Chilaiditi's syndrome is usually treated surgically because it is associated with other complications in the gastrointestinal tract. Previous studies showed the management of cases by colonic resection with primary anastomosis; however, there was one case that reported mortality due to an anastomosis leak. In this article, we present a case of Chilaiditi's syndrome associated with sigmoid volvulus and abdominal tuberculosis as seen on biopsy, which was managed surgically by colostomy followed by colostomy reversal on follow-up.

Chilaiditi syndrome in pediatric patients - Symptomatic hepatodiaphragmatic interposition of colon: A case report and review of literature

BACKGROUND

Chilaiditi syndrome is a rare disorder characterized by the hepatodiaphragmatic interposition of the intestine.

CASE SUMMARY

Here we report a case of a 12-year-old male who was admitted to the pediatric intensive care unit secondary to abdominal pain and severe respiratory distress. He was treated conservatively but the symptoms persisted requiring a surgical approach. While there have been several cases of Chilaiditi syndrome reported in adults, there is a scarcity of cases reported in the pediatric population. Our review of the literature found only 30 pediatric cases, including our reported case, with Chilaiditi syndrome, 19 (63%) of which were male. The median age of diagnosis was 4.5 years old with an interquartile range of 2.0-10.0 years. In our review, we found that the most common predisposing factors in children are aerophagia (12/30 cases) and constipation (13/30 cases). Ninety percent of the cases presented with complete intestinal interposition, in 100% of which, the colon was involved. Three of the 30 cases were associated with volvulus.

CONCLUSION

In the pediatric population, conservative (21/30 cases) and surgical (8/30 cases) treatment approaches have produced satisfactory outcomes for all the patients, regardless of approach.
