|
Gastric fold thickening
|
Gastritis (H. pylori, NSAIDS)
Gastric Ca Lymphoma |
Mets (breast, lung)
Menetrier - hypersecretory gastropathy, increased risk for gastric ca |
|
|
Cecal mass
|
Appendicitis/appendiceal abcsess
Cecal/appendiceal ca (typically large) Mucocele of the appendix (rupture can lead to pseudomyxxoma peritonei) |
Lymphoma (direct spread from TI)
Adnexal mass |
|
|
Mesenteric mass
|
Mets
-direct (pancreatic, colon) -hematogenous (breast, lung) -lymphoma -peritoneal seeding (gastric, ovarian) Carcinoid tumor -primary commonly in appendi or ileum -calcification Desmoid tumor / fibrosing mesenteritis -assoc w/ FAP and cranial osteomas (Gardner Syndrome) -fibrosing adenisitis is dx of exclusion |
Reactive LAD with central low attenuation
-Whipple disease -MAI -TB Abdominal mesothelioma -hx of asbestos esposure -ascites and serosal ST masses |
|
|
Terminal ileal wall thickening
|
IBD - Crohn's
-fistulas/strictures are hallmarks secondary to transmural inflammation -"creeping fat" causes cause bowel loops to look separated on SBFT Infection -Salmonella, campylobacter, TB -CMV or cryptosporidium in HIV Lymphoma (NHL) |
Ischemia
Mets |
|
|
Short Segment Esophageal Stricture
|
Reflux Esophagitis
Drug Induced stricture -tetracycline, doxycycline - usually superficial ulceration that heals without stricture Esophageal ca (squamous cell) |
|
|
|
Long Segment Stricture
|
Iatrogenic (NG tube)
Caustic ingestion -months to years after initial injury Radiation changes |
|
|
|
Cystic pancreatic mass
|
Pancreatic pseudocyst
Mucinous cystadenoma -benign -female -tail -large -can't differentiate from mucinous cystadenocarcinoma Serous cystadenoma -benign -middle-aged women -head -small cysts -central calcs -followed with imaging -associated with von-Hippel Lindau |
Intraductal papillary mucinous neoplasm (IPMN)
-communicate with panc duct -men=women -fill with contrast on ERCP Solid and paillary epithelial neoplasm (SPEN) -young women -tail -malignant (resection) |
|
|
Hypervascular liver mass
|
Hemangioma
-initial dicontinuous nodular peripheral enhancment -delayed central filling FNH -central scar (hyperintense on T2) -fills in on delays -composed of hepatocytes so demonstrates uptake on sulfur colloid scans (in 50%) HCC -fibromallelar HCC is a rare variant in young pts with peripheral arterial phase enhancement with a central low-density scar that does not fil in on delays -central scar is hypointense on T2 |
Hepatic adenoma
-multiple in glycogen storage ds -increased frequency with OCs Hypervascular mets -melanoma, RCC, thyroid, chorioca, pheo, islet cell, sarcomas |

Multiple splenic infrarcts |
|
|

|
Primary sclerosing cholangitis
-assoc. with UC -string of beads Ascending cholangitis -bacterial infection of an obstructed biliary system -choledocolithiasis and strictures from surgery cause biliary obstruction AIDS cholangiopathy -CMV or Cryptosporidium -multiple intraheptaic biliary strictures -distal ampullary stenosis -cholecystitis -on MRCP, alternating pattern of high signal biliary ductal dilation and intraheptaic and extrehepatic biliary strictures |
Neoplasm
-cholangioca -mets (colorectal, lung, breast, lymphoma) Post-transplant arterial ischemia |
