Colorectal mass lesions masquerading as chronic inflammatory bowel disease on mucosal biopsy.

AIMS: We bring to the attention of diagnostic pathologists a further cause of mimicry of chronic inflammatory bowel disease on mucosal biopsy, namely intramural and subserosal colorectal mass lesions. METHODS AND RESULTS: In a 10-year prospective study in one centre, we describe 26 cases in which the initial colonoscopic biopsies suggested a diagnosis of chronic inflammatory bowel disease, whereas subsequent information indicated that the mucosal changes were due to underlying mass lesions, without evidence of chronic inflammatory bowel disease. These mass lesions included underlying primary adenocarcinoma, metastatic carcinoma, pneumatosis, endometriosis and complicated diverticular disease. CONCLUSIONS: In the colon and rectum, intramural and subserosal mass lesions are a significant cause of chronic inflammatory bowel disease mimicry. Possible pathogenic mechanisms include mechanical effects, lymphatic obstruction by underlying tumour, relative mucosal ischaemia and mucosal prolapse. Since the changes seen on mucosal biopsies are a secondary phenomenon, we tentatively suggest that 'secondary colitis' may be an appropriate appellation.

[Pneumatosis cytoides coli. Conservative treatment with oxygen breathing (author's transl)].

Investigations in a 51-year old female patient suffering from severe tenesmus and therapy resistant diarrhoea led to a diagnosis of pneumatosis cystoides coli. After 4 days of treatment with continuous oxygen breathing there was dramatic clinical improvement and an incomplete radiological remission. This new method is an important step forward in the treatment of pneumatosis coli. The only potential side effect is pulmonary oxygen toxicity. Thus limitation of oxygen treatment to the shortest time necessary for abolishing symptoms is recommended. Oxygen breathing is a safe, simple and effective treatment of pneumatosis coli and may replace the currently performed surgical resection of the involved intestinal segments.

[Sonographic detection of gas in the vascular system of the liver: an image essay].

Gas within the vascular system of the liver was demonstrated sonographically in 5 patients. In contrast, plain films of the abdomen in these patients failed to demonstrate this serious finding. 3 patients presented with gas within the hepatic portal venous system, 1 patient with gas in the liver veins. In these patients, gas formation was probably caused by sepsis with gas-producing bacteria. In the last patient, air within the hepatic arterial system was caused by insufflation of air thru a port-a-cath catheter located in the main hepatic artery. The characteristic sonographic appearance of intravascular gas are highly echogenic particles flowing within the vessels. Different pathophysiologic mechanisms of gas formation in the hepatic portal venous system include sepsis with gas forming organisms, gastrointestinal necrosis of various origin in combination with elevation of intramural pressure and alteration of gas solubility of blood. The significance of sonography as a very sensitive and specific modality is outlined.

Pneumatosis cystoides coli: a rare complication of colonoscopy.

A case of colonic pneumatosis cystoides intestinales (PCI) which occurred three days after a routine colonoscopy is presented. A review of the literature revealed only two other cases of PCI following colonoscopy. The close temporal association to the colonoscopy supports the mechanical hypothesis as the probably mechanism leading to intramural PCI.

[The corroborative capacity and value of imaging diagnosis and duplex sonography in newborn infants with necrotizing enterocolitis].

In this prospective study 101 sonographic examinations of superior mesenteric artery blood flow velocities, indices and blood flow volume were consecutively performed in 41 newborn to diagnose necrotising enterocolitis (NEC). Intramural and portal venous gas was also estimated. The artifacts of air in the AMS and the portal system were examined in an experimental study. The results of sonography and abdominal radiography were equivalent in the case of definitely established NEC, portal venous gas being more sensitive to detection by sonography. Abdominal radiography was indicated as the primary examination in case of a clearly identified clinical course. Sonography should be performed so that fewer radiographs will be required in the following course of disease.

[Disseminated pneumoperitoneum during the therapy of lymphoma with methotrexate and cytosine arabinoside].

HISTORY AND CLINICAL FINDINGS: A 58-year-old man was treated for abdominal and inguinal recurrence of a centroblastic non-Hodgkin lymphoma with high doses of methotrexate and cytosine arabinoside. A chest radiogram, taken on the 18th day of chemotherapy to exclude pulmonary infiltration, revealed pneumoperitoneum. The patients's complaints were merely of abdominal fullness and persisting diarrhoea. His general state was hardly impaired, the abdomen soft on palpation with active peristalsis. INVESTIGATIONS: There was aplastic anaemia (haemoglobin 9.9 g/dl, erythrocytes 3.4 x 10(6)/microliters, white cells 1000/microliters, platelets 20,000/microliters. Plain film of the abdomen and abdominal computed tomography confirmed pneumoperitoneum. Intraluminal air had caused wall dissection in the ascending and transverse colon (pneumatosis coli as cause of the pneumoperitoneum). TREATMENT AND COURSE: There was complete absorption of the free abdominal air by the 29th day of chemotherapy under parenteral nutrition and metronidazole (3 x 500 mg daily).

[Pneumatosis coli--a rare complication of cytostatic therapy].

Recurring paroxysmal abdominal pain developed in a 19-year old woman suffering from acute lymphatic T-cell leukaemia, during induction chemotherapy with cyclophosphamide, cytarabine and mercaptopurine. Both the plain radiograph and CT of the abdomen showed pathognomonic intramural gas accumulations and free air below the right diaphragm, pointing to pneumatosis coli. There was marked pancytopenia (leucocytes 800/microliters,haemoglobin 7.6 g/dl, thrombocytes 10,000/microliters). Whereas the abdominal pain subsided rapidly under oxygen therapy and liquid nourishment, the radiological changes receded gradually. However, fever and diarrhoeas occurred subsequently. Fever persisted for 3 weeks despite treatment with antibiotics (three times 60 mg/d gentamicin, three times 2 g/d mefoxitin and three times 500 mg/d metronidazole, and later 30 mg/d amphotericin B) and subsided only after completion of the induction chemotherapy and an increase of leucocyte count.
