Pneumatosis intestinal

Christoph Kloth, Konstantin Nikolaou, Stephan Clasen
History and clinical findings: We present the case of a 63-year-old male patient free of complaints with oncological follow up examination after renal cell carcinoma (RCC) who presented extent air in the intestinal wall. Investigations and diagnosis: The computed tomography showed a pronounced pneumatosis intestinalis with punctum maximum in the part of left and less right colon flexure. Free air as a sign of perforation was not found. Treatment and course: Retrospectively, the pneumatosis intestinalis was found in fluctuating extent in several preliminary CT and MRI investigations...

Pneumatosis cystoides intestinalis (PCI) is an uncommon disease that generally lacks symptoms and is rarely associated with intussusception. A 29-year-old man visited our hospital for right upper abdominal pain. Computed tomography (CT) scan revealed multiple air-filled cysts along the intestinal wall and a pseudokidney sign in the transverse colon. A gastrographin enema examination showed a so-called crab finger appearance and multiple elevated translucency in the transverse colon. From these findings, the diagnosis of intussusception associated with PCI was made...

Objective The purpose of our study was to differentiate the imaging findings of patients with spontaneous intramural intestinal hemorrhage (SIIH) from those with acute mesenteric ischemia (AMI) after abdominal computed tomography (CT) survey in the emergency department. Methods We retrospectively included 83 patients diagnosed with SIIH or AMI after abdominal CT. Results The mean ages of 30 SIIH patients and 53 AMI patients were 74.4±14.6 years and 75.8±11.2 years, respectively. Patients with SIIH had significantly thicker maximal intestinal wall thickening (14...

BACKGROUND: Pneumatosis intestinalis (PI) is defined as the presence of gas in the bowel wall and is a relatively rare finding. PI has been associated with various pathological conditions and medications. Although several chemotherapeutic agents and molecular targeted therapy agents are reported to be associated with PI, there have been few reports describing the association between the anti-epidermal growth factor receptor agent gefitinib, a tyrosine kinase inhibitor (TKI), and PI. The present report describes a case of PI secondary to gefitinib therapy...

BACKGROUND: Pneumatosis intestinalis (PI) is known as a sign of a life-threatening bowel ischemia. We aimed to evaluate the utility of intestinal fatty acid-binding protein (I-FABP) in the diagnosis of pathologic PI. METHODS: All consecutive patients who presented to our emergency department with PI were prospectively enrolled. The diagnostic performance of I-FABP for pathologic PI was compared with that of other traditional biomarkers and various parameters. RESULTS: Seventy patients with PI were enrolled...

Emergency operations are associated with increased morbidity, mortality, and cost compared to elective operations. Palliative and emergent surgery for patients with advanced malignancies is associated with additional risk and remains controversial. Emergent or palliative interventions can be broadly categorized according to indication. Tumor related complications (bleeding, obstruction, or perforation) merit specific consideration, as do specific presentations such as pneumoperitoneum, pneumatosis intestinalis, or peritonitis from other causes that may arise during active therapy for malignancies...

Pneumatosis intestinalis (PI) is a rare disorder characterized by the gas within the intestinal mucosa. This is the first report methotrexate (MTX) induced PI under hemodialysis (HD) patient. A 46-year-old man suffered rheumatoid arthritis and underwent HD at local HD center. After the initial induction of MTX, the patient showed epigastralgia and diarrhea. He was referred to our hospital and abdominal computed tomography showed significant large intestinal edema and free intraperitoneal air consistent with PI...

INTRODUCTION: Pneumatosis intestinalis (PI) and hepatic portal venous gas (HPVG) are typically associated and are likely to represent a spectrum of the same disease. The causes of both entities range from benign to life-threatening conditions. Ischaemic causes are known to be fatal without emergency surgical intervention. PRESENTATION OF CASE: In this case a 93year old male experienced acute abdominal pain radiating to his back, with nausea and vomiting and a 2-week history of altered bowel habit...

A 77-year-old man on maintenance dialysis developed hypotension, nausea and abdominal pain one hour after beginning to undergo hemodialysis. Abdominal computed tomography (CT) showed gas shadows in the intrahepatic portal vein and the small intestinal wall, but no signs indicating intestinal necrosis. Three days later, the gas shadows on abdominal CT disappeared by conservative therapy. In cases with both pneumatosis cystoides intestinalis and hepatic portal venous gas, intestinal necrosis should therefore be suspected and surgical therapy should also be considered, particularly in hemodialysis patients with a risk of intestinal ischemia...

INTRODUCTION: Pneumatosis intestinalis (PI) and hepatic portal venous gas (HPVG) are radiographic signs of questionable bowel ischemia. Pneumatosis intestinalis can be associated with possible benign conditions such as obstructive airway disease. We present a patient who demonstrated clinical signs of overt sepsis with corresponding radiological findings of PI and HPVG concering for possible small or large bowel ischemia. However at exploration, no sign of small or large bowel injury or ischemia could be detected...

We herein report a case of pneumatosis intestinalis (PI), a condition characterized by the presence of gas within the wall of the digestive tract, associated with juvenile dermatomyositis (JDM). A 16-year-old girl, diagnosed with JDM at the age of 10, presented with abdominal pain and distention. She developed PI based on radiological findings that also included a dilated large intestine, extraluminal gas, and secondary diaphragmatic elevation. She was observed with medical therapy including bowel rest and hyperbaric oxygen therapy...

Cerebral air embolism is a rare, yet potentially fatal condition. We present a case of retrograde cerebral venous air emboli arising from the hepatic portal venous system, secondary to a mesenteric infarction. A 69-year-old man with a history of gastrointestinal amyloidosis presented with fever and lethargy. Computed tomography of the brain detected multiple foci of air in the right frontal, fronto-parietal, and left lateral frontal sulci consistent with cerebral venous air emboli. Computed tomography of the abdomen and pelvis revealed moderate thickening and dilatation of the small bowel with diffuse scattered intestinal pneumatosis suggestive of mesenteric infarction with resultant extensive intrahepatic portal venous air...

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...

OBJECTIVES: To evaluate the clinical significance of pneumatosis intestinalis (PI) including the influence on treatment and outcome. METHOD AND MATERIALS: Two radiologists jointly reviewed MDCT-examinations of 149 consecutive emergency patients (53 women, mean age 64, range 21-95) with PI of the stomach (n = 4), small (n = 68) and/or large bowel (n = 96). PI extension, distribution and possibly associated porto-mesenteric venous gas (PMVG) were correlated with other MDCT-findings, risk factors, clinical management, laboratory, histopathology, final diagnosis and outcome...

We aimed to histologically observe portal venous gas (PVG)-causing intestinal pneumatosis (IP) and evaluate pathogenic mechanisms and therapeutic strategies, including decisions on whether emergency surgery should be performed. Autopsy was performed in two cases of nonocclusive mesenteric ischemia (NOMI). We directly histologically observed the pathogenic mechanisms of IP caused by gas-producing bacteria and IP considered to be caused by mechanical damage to the intestinal mucosa. IP can be classified hypothetically into the following types according to pathogenesis: (1) infection, (2) rupture (damage) of the intestinal mucosa + increased intestinal intraluminal pressure, and (3) mixed type...

AIM: The role of ischemia in the pathogenesis of necrotizing enterocolitis (NEC) remains unclear. We used immunohistochemical markers of hypoxia to identify presence/absence of ischemia in NEC and spontaneous intestinal perforation (SIP) with clinical correlation. METHODS: Immunohistochemical staining was performed on 24 NEC and 13 SIP intestinal resection specimens using 2 hypoxia markers, hypoxia inducible factor 1α (HIF-1α) and glucose transporter 1 (GLUT1) and inflammatory markers, leukocyte common antigen (LCA) and myeloperoxidase...

A case of transient pneumatosis intestinalis with gastric pneumatosis and hepatoportal venous gas following blunt abdominal trauma is described. The presence of intramural gas mostly implies intestinal necrosis, which needs emergent surgical exploration. This case demonstrates that conservative management with close clinical observation and follow-up computed tomography scan can be safely applied in selected cases of pneumatosis intestinalis with gastric pneumatosis and hepatoportal venous gas.
