 | Media file 1: Characteristic appearance of small-bowel carcinoid. Plain abdominal radiograph in a 55-year-old man presenting with clinical features of bowel obstruction (same patient as in Images 2-5 in Multimedia). Small-bowel dilatation is confined to the upper abdomen. Speckled calcification is noted in a small, circular mass to the right of the mid lumbar spine. |
 | Media file 2: Characteristic appearance of small bowel carcinoid. Barium enema in a 55-year-old man presenting with clinical features of bowel obstruction (same patient as in Images 1 and 3-5 in Multimedia). Barium enema study shows no obstructive lesion within the large bowel, but the cecum demonstrates an extrinsic impression on its medial side (arrow). |
 | Media file 3: Characteristic appearance of small bowel carcinoid in a 55-year-old man presenting with clinical features of bowel obstruction (same patient as in Images 1-2 and 4-5 in Multimedia). Upper gastrointestinal barium series shows a smooth submucosal mass in the mid jejunum eccentrically placed and associated with thickened valvulae conniventes resulting from bowel edema and proximal small-bowel dilatation. Note the angulation of the bowel and kinking of the jejunum at the site of the submucosal mass. |
 | Media file 4: Characteristic appearance of small bowel carcinoid in a 55-year-old man presenting with clinical features of bowel obstruction (same patient as in Images 1-3 and 5 in Multimedia). Images from an indium-111 octreotide scintigraphic study (at 44 h) show the primary lesion (straight arrow, top left image), mesenteric metastases (curved open arrow, top left image), liver metastases (arrows, top right image), and a rib metastatic deposit (arrow, bottom right image); this was confirmed on postmortem study. Bladder activity, which is a normal phenomenon, is marked by a curved solid arrow (top left image). |
 | Media file 5: Characteristic appearance of small bowel carcinoid in a 55-year-old man presenting with clinical features of bowel obstruction (same patient as in Images 1-4 in Multimedia). Images from an indium-111 octreotide scintigraphic study (at 68 h) show the primary lesion (straight arrow, top left image), mesenteric metastases (curved, open arrow; top left image), liver metastases (arrows, top right image), and a rib metastatic deposit (arrowhead, bottom right image); this was confirmed on postmortem study. Bladder activity, which is a normal phenomenon, is marked by a curved, solid arrow (top left image). |
 | Media file 6: Characteristic appearance of mesenteric desmoplastic reaction from a carcinoid. Axial CT scan through the mid abdomen shows a mesenteric mass (long arrow) with shaggy borders and probable intratumoral punctate calcification (short arrow). |
 | Media file 7: Characteristic appearance of mesenteric desmoplastic reaction from a carcinoid. A 10-mm lower CT section shows stellate radiating and beaded mesenteric neurovascular bundles of the mesentery (arrows) associated with kinking (K) of the small bowel. |
 | Media file 8: Single-contrast-phase image of a barium enema study shows an eccentric narrowing of the splenic flexure associated with paucity of gas in the right hypochondrium resulting from a probable soft-tissue mass (see also Image 9 in Multimedia). |
 | Media file 9: Characteristic angiographic appearance of a carcinoid mesenteric invasion. Arterial/early capillary phase of a superior mesenteric angiogram (same patient as in Image 8 in Multimedia) shows the typical radiating configuration of the branches with tortuous peripheral vessels (curved arrows) in the region of the splenic flexure mass. Note the edge of the mesenteric mass (arrowheads) and arterial encasement (straight arrow). |
 | Media file 10: Characteristic appearance of carcinoid liver metastases with different imaging modalities. Axial sonogram through the liver shows multiple fairly well-defined echogenic liver metastases of varying sizes (see Image 11 in Multimedia for a right-sided image). |
 | Media file 11: Characteristic appearance of carcinoid liver metastases with different imaging modalities. Axial sonogram through the liver shows multiple fairly well-defined echogenic liver metastases of varying sizes (see Image 10 in Multimedia for a left-sided image). |
 | Media file 12: Characteristic appearance of carcinoid liver metastases. Contrast-enhanced axial CT scan through the upper abdomen shows early arterial enhancement of the liver metastases (see Image 13 in Multimedia for the portal venous phase). |
 | Media file 13: Characteristic appearance of carcinoid liver metastases. Contrast-enhanced axial CT scan through the upper abdomen shows portal venous phase. The metastases appear as negative defects against the normally enhancing liver (see Image 12 in Multimedia for the hepatic arterial phase). |
 | Media file 14: Characteristic appearance of carcinoid liver metastases. Gadolinium-enhanced axial MRI through the liver shows early arterial enhancement of multiple liver tumors (see Image 15 in Multimedia for the portal venous phase). |
 | Media file 15: Characteristic appearance of carcinoid liver metastases. Gadolinium-enhanced axial MRI through the liver shows portal venous phase enhancement of multiple liver tumors (see Image 15 in Multimedia for the hepatic arterial phase). |
 | Media file 16: Characteristic appearance of carcinoid liver metastases. Planar indium-111 octreotide scan shows the primary lesion (solid straight arrow), mesenteric metastases (open straight arrows), and multiple liver metastases. Bladder activity is indicated by a curved arrow (see also Image 17 in Multimedia). |
 | Media file 17: Characteristic appearance of carcinoid liver metastases. Planar indium-111 octreotide scan shows the primary lesion, mesenteric metastases, and multiple liver metastases. Bladder activity is indicated by a curved arrow (see also Image 16 in Multimedia). |
 | Media file 18: Characteristic appearance of carcinoid liver metastases. Single-photon emission CT scan obtained with indium-111 octreotide shows liver lesions in detail (see also Image 19 in Multimedia). |
 | Media file 19: Characteristic appearance of carcinoid liver metastases. Single-photon emission CT scan obtained with indium-111 octreotide shows the liver lesions in detail (see also Image 18 in Multimedia). |
 | Media file 20: Characteristic appearance of carcinoid liver metastases. Celiac-axis angiogram shows early enhancement of the liver metastases in the arterial phase (see Image 21 in Multimedia for the capillary phase). |
 | Media file 21: Characteristic appearance of carcinoid liver metastases. Celiac-axis angiogram shows persisting enhancement of the liver metastases in the capillary phase (see Image 20 in Multimedia for the arterial phase). |
 | Media file 22: Appearance of pancreatic carcinoid. Nonenhanced CT scan through the upper abdomen shows a 9-cm mass in the region of the tail of the pancreas with intratumoral pancreatic calcification and multiple mass lesions within the liver, suggestive of metastases (same patient as in Images 23-25 in Multimedia). |
 | Media file 23: Appearance of pancreatic carcinoid. Dynamic contrast-enhanced CT scan in the delayed portal venous phase shows enhancement of the pancreatic tail tumor (arrow) with central necrosis (same patient as in Images 22 and 24-25 in Multimedia). |
 | Media file 24: Appearance of pancreatic carcinoid. Right hepatic angiogram shows early enhancement of multiple liver tumors (same patient as in Images 22-23 and 25 in Multimedia). |
 | Media file 25: Appearance of pancreatic carcinoid. Left hepatic angiogram late capillary/early venous phase shows a large, left-lobe tumor with arteriovenous shunting (curved arrow). The pancreatic tumor also derives its blood supply from the left hepatic arterial circulation (straight arrows) (same patient as in Images 22-24 in Multimedia). |
