Ileal intussusception due to a parasite egg: A case report

Ileal intussusception is the invagination of the small intestine within itself and accounts for 1% of cases of acute obstruction. However, physicians do not initially consider intussusception as a possible diagnosis of obstruction due to its rarity in adults. Herein, we report the case of a 22-year-old male who was admitted to the Emergency Department with continuous abdominal pain. Ultrasonography and computed tomography revealed an ileal intussusception. The patient underwent surgical removal of the segment of the small bowel. Unexpectedly, pathology revealed that the invagination occurred due to a parasite egg, with features suggestive of Schistosoma species. Schistosomiasis, although considered a parasitic disease in tropical countries, is not absent from Europe and though it is highly improbable, it may be responsible for cases of intussusception in adults.

Adult intussusception caused by Meckel's diverticulum complicated by anisakiasis of the small intestine: report of a case

We report an extremely rare case of adult intussusception caused by Meckel's diverticulum complicated by anisakiasis of the small intestine. A 48-year-old female was admitted to our hospital with vomiting and abdominal pain 3 days after eating raw fish. The abdomen was distended with tenderness. Computed tomography demonstrated a target-shaped mass in the ileum and wall thickness of the distal ileum. We diagnosed intussusception and performed emergency surgery. At laparotomy, intussusception was already released. Since Meckel's diverticulum was observed at 40 cm and wall thickness was observed at 20 cm from the terminal ileum, we performed partial ileal resection including these lesions. On pathology, the anisakis body was found in the resected specimen of the ileum with wall thickness. The patient was discharged 8 days after surgery.

Chronic anisakidosis presenting with intestinal intussusception

OBJECTIVE

Anisakidosis is a parasitic infection caused by the ingestion of row or uncooked fish, containing larval nematodes from the Anisakidae family. Intestinal anisakidosis represents about 4% of all cases, the majority being localized in the small bowel, with rare colonic involvement. Here we present an infrequent case of chronic anisakidosis, presenting with intestinal intussusception.

CASE REPORT

A 52 years old woman, chronically treated with immunosuppressants, presented to our Institution with acute abdominal pain and vomiting, due to colocolic intussusception. Colonoscopy successfully reduced the intussusception and revealed the presence of a voluminous colonic submucosal mass, near the hepatic flexure. Therefore, the patient underwent laparoscopic right hemicolectomy. The diagnosis of anisakidosis was made when the histological examination of the surgical specimen revealed the infestation of the intestinal wall by a nematode of the Anisakidae family, with an intense erosive-inflammatory adjacent reaction.

Caecal-caecal intussusception caused by Trichuris trichiura in a young healthy adult

Trichuris trichiura is a worldwide problem affecting millions of people. We report an unusual case of intussusception caused by T. trichiura that mimics acute appendicitis. The literature on T. trichiura associated intussusception is reviewed.

Intussusception due to intestinal anisakiasis: a case report

This report describes our experience of intussusception due to intestinal anisakiasis which was treated by laparoscopy-assisted surgery. The unique sonographic findings of this complication were a pseudokidney sign and a target sign with an edema of Kerckring's folds in the intussusceptum. Surgeons should know about intussusception as a rare complication of intestinal anisakiasis. Sonography, computed tomography and laparoscopy are helpful in diagnosing and treating this complication.

Caecocaecal and caecocolic intussusceptions associated with larval cyathostomosis in four young horses

This report describes the clinical and pathological features of 4 horses affected by caecocaecal or caecocolic intussusceptions associated with larval cyathostomiasis. In each case, there was clinical and/or pathological evidence of concurrent larval cyathostomosis. They all demonstrated variable signs including diarrhoea, pyrexia, weight loss and subcutaneous oedema and cyathostome larvae were identified in the faeces of 3 of the horses. These cases highlight the need to consider caecal intussusceptions as a possible complication in horses affected by larval cyathostomosis, especially where signs of abdominal pain are severe or persistent.

Helminthic infestation complicated by intussusception in baboons (Papio hamadryas)

Two juvenile baboons presented with diarrhoea, which did not resolve completely following antibiotic therapy. Ileal intussusception was identified at autopsy in both cases. Trichuris was the only gastrointestinal pathogen for which evidence could be found. This helminth is well-recognized as a cause of intussusception in human infants, but the complication has not been reported previously in non-human primates. It is likely to be fatal if undiagnosed.
