Pneumatosis cystoides intestinalis, a rare case in a pediatric patient following allogeneic hematopoietic stem cell transplantation: CT findings and literature review. Radiol Case Rep 2021; 16:3120-3124.

Abstract
Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by the presence of gas-filled cysts in the subserosa or submucosa of the bowel wall. It is associated with various disorders including chronic obstructive pulmonary diseases, autoimmune disorders, and organ transplantation. PCI has also been observed following Hematopoietic Stem Cell Transplantation (HSCT), associated with chemotherapy, acute Graft versus Host Disease (GvHD), immunosuppression, and infections. Computed tomography (CT) provides an easy diagnosis because it highlights the presence of air bubbles in the intestinal wall and possible pneumoperitoneum. We report the case of a patient with severe acquired medullary aplasia undergoing allogeneic HSCT with subsequent development of cutaneous GvHD and an incidental finding of PCI during a CT scan of the chest in absence of gastrointestinal symptoms. Our work aims at clarifying a possible complication in pediatric patients undergoing HSCT to guide young or non-pediatric radiologists in the identification of this rare condition, helping the clinician in the correct conservative management of these patients and reserving the surgical treatment only to specific complications.

Abstract
Pneumatosis intestinalis (PI) consists of multiple, thin, gas-filled cysts in the wall of the gastrointestinal (GI) tract. It is an uncommon entity that can involve any gastrointestinal site from the stomach to the rectum. Isolated stomach involvement is rare. PI can represent a broad spectrum of diseases with variable prognoses. We present the case of a patient who was admitted with gastroenteritis-like symptoms. He remained hemodynamically stable, and on further imaging with contrast-enhanced computed tomography of the abdomen and pelvis, air was found in the portal vein and gastric wall, with minimal thickening of the proximal small bowel concerning for emphysematous gastroenteritis. Further workup results were negative, including blood cultures, stool studies, Clostridium difficile toxins, and lactic acid levels. The patient was managed nonoperatively and recovered without serious complications. Our case is unique in terms of the presence of air in the portal vein, which would otherwise suggest the possible spread of infection across the bowel wall.

Abstract
AIM Pneumatosis intestinalis (PI) is uncommon in school-age children. We studied a cohort of neurologically impaired school-age children with PI to formulate an optimum management plan. METHODS We retrospectively studied all school-age children who were referred to paediatric surgeons with radiological evidence of PI identified between 2011 and 2015. We analysed data on patient demographics, medications, feeding, associated comorbidities, presentation, investigations and treatments. RESULTS Five patients (3F:2M) with a median age of 7 years (range 5-9) were referred for surgical opinion with the evidence of pneumatosis on their abdominal X-rays. Four of them had associated pneumoperitoneum. All children had neurological impairment significant enough to make them unable to communicate clearly. Four patients were gastrostomy fed, one was jejunally fed. Four children had recurrent episodes of pneumatosis. Four patients had surgery at the initial presentation where colonic pneumatosis was detected; however, there was no evidence of bowel ischaemia or perforation despite of the presence of pneumoperitoneum. Recurrent episodes were successfully managed conservatively even in the presence of pneumoperitoneum. CONCLUSION In neurologically impaired school-age children, the presence of pneumatosis and pneumoperitoneum does not mandate bowel ischaemia or perforation and therefore could be successfully managed conservatively without the need for surgery.

Abstract
This case series describes our experience in managing 4 children with complex neurodisability, feed intolerance, and pneumatosis coli. In all of the 4 patients, symptoms and feed tolerance were substantially improved by the formation of a laparoscopically assisted defunctioning ileostomy. We describe our present management strategy and believe this is a promising treatment for those patients who can reduce long-term dependence on parenteral nutrition, although we acknowledge that there is a long-term risk of disuse colitits in the defunctioned bowel.

Abstract
INTRODUCTION Pneumatosis cystoides intestinalis (PCI) is an uncommon condition. This following article describes a case of primary PCI presenting as acute abdomen due to perforation of a small bowel cyst. PRESENTATION OF CASE This following article describes the case of an 88 year-old woman admitted at the hospital with peritonitis and consequently operated for a presumed bowel ischemia and perforation. However surgical exploration revealed perforated PCI. DISCUSSION The pathophysiology of secondary PCI is poorly understood. Gas produced by Gas-forming bacteria may enter the mucosal barrier due and consequently this gas accumulates within the bowel wall. Also malnutrition can prevent the digestion of carbohydrates, which leads to increased bacterial fermentation, and production of large volumes of gas leading to distention and ischemia and subsequently the submucosal dissection of gas. Colonoscopy is helpful in excluding other colonic lesions and it shows the submucosal cysts that have a typical dual appearance: multiple white small cysts coupled to a sub-atrophic mucosa or larger cysts (up to 3cm) with a reddened overlying mucosa. CONCLUSION The treatment unless complicated should be conservative even in the presence of pneumoperitoneum, after excluding complications.

Abstract
Pneumatosis cystoides intestinalis (PCI) is a rare condition that may be associated with a variety of diseases. The presenting clinical picture may be very heterogeneous and represent a challenge for the clinician. In the present paper we describe both a common and an uncommon clinical presentation of PCI and review the pertaining literature. Our cases confirm that, apart from asymptomatic cases, the clinical presentation of PCI may be widely different and suggest that a new onset of stipsis might be the presenting symptom. Diagnosis might be suggested by a simple X-ray of the digestive tract showing a change in the characteristics of the intestinal wall in two-thirds of these patients. However, one third of the patients do not have a suggestive X-ray and require a computed tomography (CT) scan/nuclear magnetic resonance that may reveal a thickened bowel wall containing gas to confirm the diagnosis and distinguish PCI from intraluminal air or submucosal fat. CT also allows the detection of additional findings that may suggest an underlying, potentially worrisome cause of PCI such as bowel wall thickening, altered contrast mucosal enhancement, dilated bowel, soft tissue stranding, ascites and the presence of portal air. Our results also point out that clinicians and endoscopists should be aware of the possible presentations of PCI in order to correctly manage the patients affected with this disease and avoid unnecessary surgeries. The increasing number of colonoscopies performed for colon cancer screening makes PCI more frequently casually encountered and/or provoked, therefore the possible endoscopic appearances of this disease should be well known by endoscopists.

Abstract
Pneumatosis intestinalis (PI), defined as gas within the bowel wall, is an uncommon radiographic sign which can represent a wide spectrum of diseases and a variety of underlying diagnoses. Because its etiology can vary greatly, management of PI ranges from surgical intervention to outpatient observation (see, Greenstein et al. (2007), Morris et al. (2008), and Peter et al. (2003)). Since PI is infrequently encountered, clinicians may be unfamiliar with its diagnosis and management; this unfamiliarity, combined with the potential necessity for urgent intervention, may place the clinician confronted with PI in a precarious medical scenario. We present a case of pneumatosis intestinalis in a patient who posed a particularly challenging diagnostic dilemma for the primary team. Furthermore, we explore the differential diagnosis prior to revealing the intervention offered to our patient; our concise yet inclusive differential and thought process for rapid evaluation may be of benefit to clinicians presented with similar clinical scenarios.

Abstract
Intraperitoneal free air in a child with acute lymphoblastic leukemia (ALL) treated with induction chemotherapy is an ominous sign suspective of gastrointestinal perforation. We report a case of pneumatosis cystoides intestinalis (PCI) with free intraperitoneal air without bowel perforation in a child with Down syndrome during ALL induction treatment. PCI is a physical sign characterized by gas-filled cysts of the submucosa or subserosa of the bowel that can lead to pneumoperitoneum. Clinical management of this case in respect to reported literature on PCI and specific characteristics of patients treated with ALL induction chemotherapy are discussed.

Abstract
Objective Pneumatosis intestinalis has been increasingly detected in recent years with the more frequent use of computed tomography for abdominal imaging of the intestine. The underlying causes of the gas found during radiographic studies of the bowel wall can vary widely and different hypotheses regarding its pathophysiology have been postulated. Pneumatosis intestinalis often represents a benign condition and should not be considered an argument for surgery. However, it can also require life-threatening surgery in some cases, and this can be a difficult decision in some patients. Methods The spectrum of pneumatosis intestinalis is discussed here based on various computed tomographic and surgical findings in patients who presented at our University Medical Centre in 2003-2008. We have also systematically reviewed the literature to establish the current understanding of its aetiology and pathophysiology, and the possible clinical conditions associated with pneumatosis intestinalis and their management. Results Pneumatosis intestinalis is a primary radiographic finding. After its diagnosis, its specific pathogenesis should be ascertained because the appropriate therapy is related to the underlying cause of pneumatosis intestinalis, and this is sometimes difficult to define. Surgical treatment should be considered urgent in symptomatic patients presenting with an acute abdomen, signs of ischemia, or bowel obstruction. In asymptomatic patients with otherwise inconspicuous findings, the underlying disease should be treated first, rather than urgent exploratory surgery considered. Extensive and comprehensive information on the pathophysiology and clinical findings of pneumatosis intestinalis is provided here and is incorporated into a treatment algorithm. Conclusions The information presented here allows a better understanding of the radiographic diagnosis and underlying aetiology of pneumatosis intestinalis, and may facilitate the decision-making process in this context, thus providing fast and adequate therapy to particular patients.

Abstract
While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis.

Abstract
The presence of intraperitoneal free air signals perforation of a hollow viscus in over 90% of the patients. Rarely, however, the presence of pneumoperitoneum may not indicate an intra-abdominal perforation and thus may not require laparotomy. This condition, which poses a dilemma to the surgeon faced with this problem, is termed "nonsurgical", "spontaneous" or "idiopathic" pneumoperitoneum. Six cases of nonsurgical pneumoperitoneum admitted over a 2-year period to our institution are reported, and the etiological mechanisms and the pathophysiology of the appearance of intra-abdominal free gas are reviewed. Two of the six children with nonsurgical pneumoperitoneum underwent exploratory laparotomy when clinical examination suggested an acute abdomen; no intra-abdominal pathology was documented in one of these patients. In the other children, malrotation was found. Four patients, on ventilatory support, were managed conservatively after performing a diagnostic peritoneal lavage and/or contrast studies those were negative. An appreciation of the condition and its likely etiological factors should improve awareness and possibly reduce the imperative to perform emergency laparotomy on an otherwise well patient with an unexplained pneumoperitoneum.

Abstract
OBJECTIVES To describe fully pneumatosis intestinalis (PI) in non-neonatal pediatric patients and to characterize those patients with higher risk of poor outcome, including need for surgery and death. METHODS A retrospective chart review was conducted of all patients 30 days of age and older with PI in a tertiary care children's hospital during an 8-year period. Underlying medical condition, presenting signs and symptoms, radiologic grade of pneumatosis, and events that immediately preceded the onset of PI were reviewed, and their correlation with outcome was assessed. RESULTS Thirty-seven episodes of PI occurred in 32 patients. Seventy-eight percent of patients were male, and the median age was 29 months. Major patient diagnostic groups identified with PI included healthy children (22%), patients with organ and bone marrow transplant (22%), patients with decompensated congenital heart disease (12.5%), motility disorders (12.5%), gastroschisis (9%), and short bowel syndrome (6%). The most common events that immediately preceded the onset of PI were noninfectious colitis (32%), acute enteric infection or toxin (27%), bowel ischemia (20%), and gastrointestinal dysmotility (17%). Resolution of PI with medical management occurred in 78% of episodes (good outcome). Twenty-two percent of episodes resulted in a poor outcome: patient death (8%) or surgery (14%). The presence of portal venous gas and low mean serum bicarbonate concentration were the only clinical factors that correlated significantly with poor outcome. Only 25% of patients with pneumoperitoneum required surgery. Poor outcome was seen most commonly in 2 patient diagnostic groups: transplant patients (43% of patients) and decompensated cardiac disease (50% of patients). The event that preceded PI also had an impact on outcome. PI preceded by ischemia or graft versus host disease colitis was associated with poor outcome in 50% and 75% of cases, respectively. CONCLUSIONS PI is a radiologic sign that occurs in a variety of settings in non-neonates. PI preceded by bowel ischemia or graft versus host disease colitis has the worst prognosis, and the presence of portal venous gas and acidosis correlate with poor outcome. Not all patients with pneumoperitoneum require surgical intervention. Overall, outcome of PI in non-neonatal patients was better than that reported in neonates with necrotizing enterocolitis.pneumatosis intestinalis, necrotizing enterocolitis, non-neonatal.

Abstract
The authors describe a 3-year-old boy with pneumatosis cystoides intestinalis (PCI) and associated duodenal stenosis who came to them with abdominal pain, significant abdominal distension, large gastric residue, and pneumoperitoneum. PCI is a rare condition in children characterized by the presence of multiple gas-filled cysts within the wall of some part of gastrointestinal tract that may break and cause pneumoperitoneum without an intestinal perforation. Even if in most cases the standard treatment is surgical, to keep in mind this rare condition could be useful to adopt a most rational treatment approach and avoid unnecessary operation in case of "benign" pneumoperitoneum.

Abstract
BACKGROUND/PURPOSE Chronic intestinal pseudo-obstruction (CIP) in infants and children is a motility disorder without apparent mechanical cause. Nitric oxide (NO), an inhibitory neurotransmitter and c-kit cells, essential for the intestinal pacemaker activity, both play a key role in the intestinal motility function. In the current study, the authors investigated the distributive change in the intestinal nitric oxide synthase (NOS) and c-kit cells of patients with CIP. METHODS Tissues were obtained from 4 patients undergoing bowel resection or biopsy for CIP at laparotomy. For controls, the intestinal specimens were obtained from 4 age-matched cases of intestinal stricture, intussusception, and autopsy with no evidence of gastrointestinal disease. Immunohistochemical studies were performed on paraffin-embedded tissue cross sections with neuronal NOS and inducible NOS monoclonal antibody as well as a rabbit polyclonal antibody against the human c-kit receptor. RESULTS Under immunohistochemical staining, a greatly increased density of neuronal NOS immunoreactivity and an evidently increased number of intense NOS immunoreactive nerve fibers were observed in the myenteric plexus and circular muscle layers compared with the control sections. In the submucosal plexus and longitudinal muscle layer, there was no change in NOS immunoreactivity. Inducible NOS immunoreactivity was not detected in the control cases. However, in tissues of CIP, almost all the epithelial cells were positively and strongly labeled for inducible NOS immunoreactivity. For c-kit cells staining, the number of c-kit-positive cells in the myenteric plexus and circular muscle layers were greatly less than that in the controls, especially in the myenteric plexus region. CONCLUSION These findings suggest that sustained production of NO by an increased NOS activity and a deficiency of c-kit cells in the intestine may be related to the pathogenesis of CIP.

Abstract
For many patients, nutritional support and relief of symptoms remain the primary management goal of pseudo-obstruction. Specific pharmacological agents for this disorder are, in general, lacking. Given that the efficacy of many of the individual available agents is far from excellent, several centers have turned to combination therapy. Though there is at present no evidence from controlled studies to support this strategy, it is, at the very least, theoretically attractive as these agents act through a number of separate mechanisms. The combination of a prokinetic and an emetic may prove especially useful. As the pseudo-obstruction syndromes are, individually, rare, and experience with any given prokinetic agent in these disorders limited, it is difficult to develop strict guidelines for their use in this context. It stands to reason that a response to a prokinetic agent would seem unlikely in a patient with an advanced myopathic process; anecdotal evidence suggests, however, that some patients with severe scleroderma may derive some symptomatic improvement. Where oral therapy is tolerated, cisapride would appear the best choice among available agents. When this fails, subcutaneous octreotide may be added or substituted. In the acute situation, intravenous erythromycin may alleviate gastroparesis, but probably exerts little beneficial effect beyond the pylorus; parenteral metoclopramide may be tried, but, here again, convincing evidence of efficacy is lacking. The roles of endoscopy and surgery are largely confined to facilitating nutrition and providing decompression.

Abstract
Pneumatosis cystoides intestinalis is a rare condition characterized by multiple subserosal or submucosal gas filled cysts within the wall of a segment of bowel. It is associated with numerous conditions, both intra and extraabdominal in nature. The condition may be asymptomatic or may present clinically as nausea, vomiting, diarrhea or other signs of intestinal obstruction. With rupture of the cysts, pneumoperitoneum may be a finding. In a patient with vague clinical presentation, this finding radiographically may lead to a clinical dilemma as many of these patients have comorbid conditions which are also associated with intestinal perforation. The authors present the case of a 47-year-old obese black female found to have massive pneumatosis intestinalis of the tranverse colon with a small amount of free intraperitoneal air. This case highlights the importance of recognizing pneumatosis intestinalis as a possible mimic of free intraabdominal air as well as a possible cause of benign pneumoperitoneum.

Abstract
Pneumatosis intestinalis (PI) is characterized by subserosal or submucosal gas-filled cysts of the gastrointestinal tract. The course may be benign or may lead to the need for urgent surgery. Knowledge of the differential diagnosis, course, and treatment modalities are key in providing optimal care to patients who present with this entity. In this article, two cases of "benign" pneumatosis seen at our institution over a one-month period are presented, along with a retrospective review of the English literature from January 1985 to March 1995. Incidence, symptoms, gross and microscopic appearance, radiographic appearance, etiology, differential diagnosis and therapy are reviewed.

Abstract
Cystic fibrosis is most often the underlying cause of meconium ileus. We describe the diagnosis and treatment of a patient with chronic intestinal pseudo-obstruction, and not with cystic fibrosis, whose initial manifestation was meconium ileus.
