Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by the presence of multiple gas containing thin walled cysts in the intestinal wall and mesentery. It is sometimes associated with chronic obstructive pulmonary disease, but has been described most often in patients with gastrointestinal disorders including duodenal and gastric ulceration, small bowel obstruction, regional enteritis and gastrointestinal malignancy. Its association in the patient described below with severe systemic sclerosis is of particular interest. There have been occasional previous reports of this association which should be considered in any patient with systemic sclerosis who develops abdominal symptoms suggestive of acute or sub-acute intestinal obstruction, not readily explicable by other causes.

Pneumatosis cystoides intestinalis is an uncommon disease characterized by submucosal or subserosal collections of gas in the gastrointestinal tract and its peritoneal attachments. The literature suggests that the clinical course of this illness may be benign and self-limited. Clinical manifestations range from nonspecific gastrointestinal complaints to life-threatening complications of intestinal obstruction or pneumoperitoneum. Radiographic evidence of pneumoperitoneum in relatively asymptomatic patients suggests pneumatosis cystoides intestinalis. Correct radiographic diagnosis may avoid unnecessary surgery. In this unusual case, a patient with apparent subdiaphragmatic free air on radiograph was diagnosed as having pneumatosis cystoides intestinalis that involved the submucosa of the stomach and was related only to severe gastric dilatation. The case was managed expectantly, resulting in resolution of all radiographic findings and complete symptomatic recovery.

Pneumatosis coli is a rare condition in which gas filled cysts occur in the wall of the intestines. Most symptomatic patients can be managed conservatively but those who fail medical management or who develop bowel obstruction will require surgery. Surgery usually involves a limited colectomy with a potential for recurrence. We describe a case of pneumatosis coli managed successfully by restorative proctocolectomy and ileal pouch-anal anastomosis.

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.

Pneumatosis cystoides intestinalis involving the left side of the colon has been infrequently described. The condition was recognized 234 years ago when it was discovered in a cadaver. It was not until 1946, however, that a description of this lesion appeared in the radiological literature of North America. Pathologically, it is characterized by the presence of subserosal or submucosal cysts, varying from one millimetre to several centimetres in diameter. The complications of this process are pneumoperitoneum and intestinal obstruction. Three patients are described, the first of whom had partial bowel obstruction. Radiolucent gas-filled cysts along the bowel wall were observed on the radiographs. An additional radiological sign noted by the authors was fixation and elongation of the sigmoid colon with loss of pliability of the bowel wall which persisted on the evacuation film.

Pneumatosis cystoides intestinalis is an uncommon condition characterized by gas filled cysts within the bowel wall. We present a case of a 40-year old male who complained of abdominal pain and distension. The clinical diagnosis was intestinal obstruction and intraoperative impression was intestinal lymphangioma. The resected segment of the bowel showed multiple thin walled, tense, air-filled cysts on the serosal surface, which collapsed with a popping sound when pricked. The histologic diagnosis was pneumatosis cystoides intestinalis. Pneumatosis cystoides intestinalis has varied clinical manifestations, course and outcome depending on its benign or fulminant form. There are varying theories regarding its pathogenesis and it is seen in association with a variety of diseases. Hence it should be interpreted with relevance to its entire clinical context, as it may not be a disease in itself but a sequel to other conditions.

Pneumatosis cystoides intestinalis (PCI), with an unknown etiology, is an uncommon disease characterized by the presence of multiple gas-filled cysts within the submucosa or subserosa of the intestinal wall. Intestinal obstruction and/or perforation are relatively uncommon complications associated with PCI. The patients are often prone to misdiagnosis or mistreatment. The diagnosis of PCI is based on plain radiography or endoscopy. Multidetector computed tomography (MDCT) provides data on other intra-abdominal pathologies. Therefore, it is an important modality for the diagnosis of PCI. We present a case of PCI in a 58-year-old man affected by peritoneal free air with multidetector computed tomography imaging findings. We performed the plain film of the abdomen, and MDCT studies that showed numerous, diffuse, bubble-like intramural gas collections into the jejunum, ileum, and colon walls at the left-upper quadrant of the abdomen. MDCT findings were confirmed by surgical exploration.

Pneumatosis intestinalis is a rare condition that affects 0.03% of the population. Pneumatosis cystoides intestinalis (PCI) is characterized by the presence of multiple gas-filled cysts in the intestinal wall and the submucosa and/or intestinal subserosa. It is usually a secondary finding caused by a wide variety of underlying gastrointestinal or extragastrointestinal diseases. Here, we present the case of a 47-year-old man who was referred to our gastroenterology department with a history suggestive of intermittent small bowel obstruction associated with abdominal pain. Abdominal computed tomography demonstrated PCI of the small bowel. The mesentery and branches of the superior mesenteric artery and superior mesenteric vein were twisted with minimal pneumoperitoneum. Exploratory laparotomy was performed, and demonstrated segmental small bowel PCI secondary to hypermobile mesentery. The affected segment of the ileum was resected, and jejunoileal anastomosis was performed. Here, we report a rare case of segmental PCI probably due to repeated twisting of hypermobile mesentery. The clinical and imaging features of this disorder may mimic those of visceral perforation or bowel ischemia. PCI can be a cause of severe abdominal pain that may require surgical intervention.

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple gas-filled cysts of varying size in the wall of gastrointestinal tract. PCI may idiopathic or secondary to various disorders. The etiology and pathogenesis of PCI are unclear. Treatment is usually conservative, and includes oxygen and antibiotics therapy. Surgery is reserved for cases of suspected inconvertible intestinal obstruction or perforation. Eleven patients who were diagnosed with PI between 2005 and 2015 were reviewed. We report three cases of PCI and describe causes and complications. The most important point in the treatment of PCI is to determine whether the patient needs surgery. Conservative care should be considered first if the patient is stable. If any complication is observed, such as ischemia in the intestine, surgery is needed. It is important to choose the best treatment based on prognostic factors and CT findings.

A 54-year-old woman underwent colonoscopy for colon cancer screening. Colonoscopy showed multiple cysts in the sigmoid colon, with the largest being 4 cm in diameter. One of the cysts was biopsied. Cyst walls were observed; during biopsy, the gas was released and the cyst collapsed. Computed tomography of the abdomen confirmed a diagnosis of pneumatosis cystoides intestinalis. Pneumatosis cystoides intestinalis is a rare disease characterized by the presence in the intestinal submucosa or subserosa of multiple cysts filled with gas (nitrogen, oxygen, carbon dioxide and hydrogen). This condition occurs more often in males than in females, with cysts most frequently located in the colon. Causes may include elevated intraluminal pressure, pulmonary diseases, bacterial gas production, malnutrition, chemotherapy, connective tissue diseases, among others. Symptoms of pneumatosis cystoides intestinalis include abdominal pain, diarrhea, bloating and gastrointestinal bleeding. This condition is diagnosed by endoscopy or computed tomography of the abdomen. Conservative treatment is successful in 93% of patients. However, 3% of patients develop complications such as intestinal obstruction or perforation.
