A case of arteriovenous malformation of the spinal canal in a 8 year-old girl is reported. This child complained of night abdominal pain for several months, without diagnosis. Plain X-ray showed an enlargement of the lumbar spinal canal. Magnetic resonance imaging diagnosed a spinal vascular malformation, which was confirmed by angiography. Interest of MRI in such a case is emphasized.

A 7-year-old girl with an unremarkable family history was admitted with complaints of diarrhea containing mucus and blood, abdominal pain, weight loss and fever for 10 months. Although her symptoms, physical examination and laboratory results were highly suggestive of inflammatory bowel disease, radiologic studies and colonoscopy demonstrated multiple colonic polyps. A bilateral and symmetric lamellar periosteal reaction and osteopenia were present on her extremity radiographs. The chest radiograph and thoracic CT scan were normal. The histologic nature of the polyps was determined as hamartoma. One month after subtotal colectomy, the patient's symptoms resolved and she gained 7 kg in weight. The association of generalized juvenile polyposis and hypertrophic osteoarthropathy has previously been described in five cases; arteriovenous malformations were present in four of them. In our case the polyps were hamartomatous and localized in the colon, without associated arteriovenous malformation.

We describe a case of a patient with previously diagnosed of ulcerative colitis, who was admitted to the hospital because of rectal bleeding and abdominal pain. A mild active colitis was reported by colonoscopy with biopsy. Rectal bleeding relapsed, and an arteriovenous malformation in the transverse colon compatible with angiodysplasia was located by early vascular scintigraphy with 99m-technetium-labeled red blood cells. This finding was confirmed by selective arteriography. Four months after hemicolectomy, the patient is free of rectal bleedings. Labeled red blood cell scintigraphy may be useful to differential diagnosis of lower digestive hemorrhage.

A 26 year-old female presented with progressive intermittent right upper quadrant pain. Hepatic arteriovenous malformation with small intrahepatic bilomas were found. She underwent hepatic artery ligation for control of her abdominal pain. Though the abdominal pain subsided after the hepatic artery ligation, the intrahepatic bilomas progressed. It is possible that the hepatic arteriovenous malformation (AVM) might reduce blood flow to the bile duct and then induce ischemia in the peribiliary capillary plexus, thus leading to bile duct necrosis and formation of bilomas, which could be further aggravated by hepatic artery ligation.

Arteriovenous malformation of the pancreas is a very rare entity. We describe a case involving the head of the pancreas associated with progressive hemobilia bleeding from the lower part of the common bile duct. The patient was a 50-year-old man with acute epigastralgia. Endoscopic retrograde cholangiopancreatography revealed hemobilia and cystic dilation of the common bile duct. Angiography demonstrated increased blood volume in the head of the pancreas and early filling of the superior mesenteric and portal veins. Abdominal pain and progressive anemia caused by hemobilia required surgical treatment. Histologic examination of the resected specimen revealed marked proliferation of the blood vessels in the pericholedochal area and the exact point of bleeding from the pancreaticobiliary arteriovenous malformation.

With the exception of angiodysplasia, vascular abnormalities of the intestines are unusual. We describe a florid benign vascular proliferation of the colon in five adult patients, three of whom presented with idiopathic intussusception. In all cases, the proliferation was sufficiently exuberant to raise the possibility of angiosarcoma as a diagnostic consideration. The group included 2 males and 3 females with a median age of 43 years. Two patients were HIV positive. Four patients presented with a colonic mass; other symptoms at presentation included abdominal pain, diarrhea, bleeding, and bowel obstruction. In all cases, a florid lobular proliferation of small vascular channels lined by plump endothelial cells extended from the submucosa through the entire thickness of the bowel wall. The endothelial cells showed minimal nuclear atypia, and mitotic figures were infrequent. The overlying mucosa showed ulceration with ischemic-type changes, and had features of mucosal prolapse. A possible underlying arteriovenous malformation was identified in two cases. All patients were alive and well at last follow-up (interval, 6 months to 5 years). The presence of intussusception or mucosal prolapse in all of the cases suggests repeated mechanical forces applied to the bowel wall as a possible etiologic factor. The role of HIV infection in the pathogenesis of these lesions remains to be determined.

Pancreatic arteriovenous malformation (PAVM) is a rare condition that may cause duodenal ulcer. A 36-yr-old man with PAVM associated with duodenal ulcer and H. Pylori infection is described. The patient had recurrent episode of upper abdominal pain despite healed ulcer and H. Pylori eradication. The preoperative diagnosis was confirmed by computed tomography and the patient was treated with a pancreatoduodenectomy. Histological examination of the resected pancreas revealed a pancreatic arteriovenous malformation involving the adjacent duodenal wall.

Arteriovenous malformation (AVM) of the pancreas is a rare condition that may cause severe gastrointestinal bleeding. We describe a 54-year-old man with a 7-year history of recurrent duodenal ulcer due to AVM in the pancreatic head. We recommended pancreatoduodenectomy because of recurrent haemorrhage from the duodenal ulcer, but the patient refused surgery on several occasions. He was admitted to our hospital complaining of severe upper abdominal pain radiating to the back and was diagnosed with acute pancreatitis. He agreed at that stage to the surgical treatment. The resected specimen contained a highly vascular malformation in the pancreatic head and ulceration in the adjacent descending duodenum. Histopathological examination revealed numerous vascular structures with dilated and tortuous vessels in the pancreatic head, confirming the presence of AVM. Moreover, oedema, inflammatory cell infiltration, haemorrhage and necrosis were evident, confirming the presence of acute pancreatitis.

In three patients with persistent blood loss from bleeding or abnormal renal vessels, kidney function was preserved by treatment with selective embolisation. The first patient, a 42-year-old woman, suffered from persistent haematuria after undergoing percutaneous nephrolithotripsy on the left side. Because conservative methods had failed and renal artery bleeding as a result of the lithotripsy was suspected, angiography with selective coil embolisation of a segmental branch of the lower pole artery of the kidney was performed. The second patient, a 40-year-old man with severe haemophilia A had been suffering from recurring macroscopic haematuria for a few months. CT showed an arteriovenous malformation in the right kidney. Angiography in combination with embolisation with two detachable balloons resulted in occlusion of the malformation. The third patient, a 23-year-old woman with tuberous sclerosis, presented with left abdominal pain, haematuria and decreasing haemoglobin concentrations. CT revealed a left renal angiomyolipoma, 10 cm in size, with a large internal haematoma. Three pathological branches of the upper pole renal artery were successfully occluded with Gianturco coils. At follow-up after 2, 2.5 and 2.5 years respectively, no recurrence of bleeding had occurred. Selective embolisation should be attempted as means of treatment for persistent renal bleeding if conservative treatment fails. Selective embolisation is minimally invasive and has the important advantage of preserving renal function.

We report a case of a 57-year-old male with a pancreatic arteriovenous malformation (AVM). The diagnosis was made by CT scan and angiography. In the reported case, bleeding from AVM into the biliary tract caused haemobilia and bleeding into the pancreatic head caused abdominal pain. Pancreatic AVM has been only rarely reported as a cause of haemobilia.
