The Authors describe a case of double jejunal diverticulum, characterized by the presence of a leiomyosarcoma in one diverticulum and ectopic pancreatic mucosa in the other. The rarity of the occurrence of a leiomyosarcoma in the diverticular area is outlined; only few cases have been reported in Literature, excluding those originating, from Meckel's diverticulum. Barium X-rays of the small intestine allowed the neoplasia to be discovered, while an Echo-Color-Doppler examination suggested the histological type given the high vascularization typical of leiomyosarcomas.

Meckel's diverticulum (Md) is the most common congenital anomaly of the gastrointestinal tract. It results from an incomplete obliteration of the omphalomesenteric duct during fetal life. It is frequently located on the antimesenteric border of the ileum at 80 cm from the ileum-cecal valve. It contains heterotopic mucosa in 30% of the cases and in 70% of these the mucosa is of the gastric type. The most common complication in childhood is represented by hemorrhage. Preoperative diagnosis is often difficult. Barium enema, Tc-99 scintigraphy and selective mesenteric angiography usually can permit diagnosis. In adults occlusion, perforation, diverticulum infection, Littre's hernia and tumors represent the complications of Meckel's diverticulum. A case of Md is reported because of the unusual clinical presentation.

Meckel's diverticulum is a common anomaly of the GI tract that is known to cause small intestinal obstruction. A 17-yr-old male who had no history of previous surgery was admitted with intermittent abdominal pain. A barium enema showed extraintestinal compression of the ascending colon, suggesting the existence of a congenital band. Laparoscopy revealed that the ascending colon was lifted up and compressed by the intestinal end of a Meckel's diverticulum with a fibrous band connecting to the umbilicus. The portion of the ileum including the Meckel's diverticulum was resected. This is the first case of stenosis of the colon caused by a Meckel's diverticulum.

A 71-year-old woman was admitted to hospital because of malaise and bloody stool. Laboratory findings consistently showed anemia (Hb 9.2 g/dl) and occult blood in the stool. Although barium series and endoscopy of the upper and lower intestinal tructs were carried out, there was no evidence of bleeding from the gastrointestinal tract 99mTcO4- scintigraphy, which was performed to exclude bleeding from Meckel's diverticulum, also did not locate a significant lesion. Angiographic imaging of the superior mesenteric arteries (SMA) was performed to exclude lesions such as small intestine tumors with extraluminal growth and vascular abnormalities such as A-V malformation and it revealed the round encasement of arteries in the peripheral SMA region, strongly suggestive of a small intestine tumor. Surgery was performed and an extraluminally protruding tumor was found in the small intestine. The excised tumor was 4 x 3 x 3.5 cm in size, are was diagnosed histologically as aberrant pancreas. The postoperative laboratory findings showed that the anemia had improved and occult blood was not detected in the stools. Although aberrant pancreas of the small intestine is a common benign tumor, it is a very unusual cause of bleeding from the alimentary tract.

We report a case of Meckel's diverticulum in a 6-month-old girl who presented with a 5-month history of chronic screaming but no symptoms or signs of intestinal obstruction. Infantile colic was the presumptive diagnosis. Abdominal sonography at 6 months of age demonstrated an abdominal mass with an anechoic center and a double-layered wall, surrounded by bowel loops. Abdominal CT and barium enema x-ray studies demonstrated nonspecific findings of a cystic mass with compression of adjacent bowel loops. Histologic examination of the resected mass revealed a Meckel's diverticulum with a perforation sealed off by the neighboring bowel and mesentery to form an inflammatory mass.

Meckel's diverticulum is the most common anomaly of the gastrointestinal tract and usually produces no symptoms, although the classic symptom is painless rectal bleeding in a child. Because most symptomatic diverticula in children contain ectopic gastric tissue, radionuclide imaging using a technetium 99m pertechnetate scan is considered to be the method of choice. However, a bleeding Meckel's diverticulum may not be detected by pertechnetate imaging despite the presence of ectopic gastric mucosa. When the scan is negative, visceral angiography is an alternative procedure for detecting Meckel's diverticulum. We encountered a case of pathology-proven Meckel's diverticulum whose angiography result was diagnostic, while upper gastrointestinal panendoscopy, colonofibroscopy, barium enema studies, and repeated radionuclide scans were all negative. We report on this case to emphasize the potential role for angiographic detection of Meckel's diverticulum.

Meckel's diverticulum is the congenital anomaly of the gastrointestinal tract affecting about 2% of the population. It is a true diverticulum containing all layers of the ileum wall. Heterotopic tissue is frequently present (25%): gastric mucosa, duodenal mucosa, jejunal mucosa and pancreatic tissue. Meckel's diverticulum is localized about 50 cm from the ileo-colic valve on the external border of the ileum. Most of Meckel's diverticula are clinically silent; clinical symptoms (19%) are in cases of complications such as: strangulation of the bowel in a ring formed by the diverticulum, intussusception of the diverticulum into the ileum, volvulus, incarceration of the diverticulum in hernia, tumour originating in the diverticulum. The diagnosis of Meckel's diverticulum is very difficult. The most useful in the diagnosis are plain abdominal radiographs, barium studies, CT, sonography and scintigraphy Abdominal sonography shows a tubular fluid structure localized far from the coecum. The wall of the diverticulum is swollen and in the lumen are chyme or fat.

A 32-year-old man presented with severe abdominal pain located in the mesogastrium and right hemi-abdomen. A barium transit study showed a tubular structure of 6 cm arising from a bowel loop in the distal ileum, with an intraluminal polypoid mass near the bottom. Diagnosis of a benign lesion within a Meckel's diverticulum was made. Anatomopathology confirmed a Meckel's diverticulum and demonstrated that the polypoid mass was caused by an unusual great ectopic island of gastric mucosa.

An 11-year-old boy presenting with serious rectal bleeding had a negative Meckel scintigraphy. On a barium small bowel followthrough, a small accumulation of contrast was seen outside the contour of the ileum, caused by a Meckel's diverticulum after all.

Chronic intussusception as a cause of persistent abdominal pain in children is often an overlooked diagnosis. Here we present an eight-year-old boy, who at the age of three years had an acute intussusception reduced hydrostatically with barium and who subsequently had been extensively investigated both in Wales and in Switzerland, for persistent colicky abdominal pain. He was found to have chronic intussusception, with a Meckel's diverticulum being the cause of his symptoms.
