Other Pathologies Flashcards
Are true cyst common
no, its rare
Multiple pan cyst are assoc with
adult polycystic kidney disease and von Hippel-Lindau syndrome
Exocrine gland disorder resulting in viscous secretions causing pancreatic dysfunction
cystic fibrosis
SF of cystic fibrosis
- increased pancreatic echogenicity
- gland atrophy
- fibrosis and fatty replacement
- cysts due to ductal obstruction
Common assoc with cystic fibrosis
meconium ileus
Cystic fibrosis pancreas is
hyper
Cystic fibrosis is common in
children
Failure of the dorsal and ventral pancreatic ductal systems to fuse during embryonic development resulting in smaller Santorini’s duct draining the pancreas
Pancreas Divisum
In pancreas divisum, inadequate pancreatic enzyme drainage may result in
pancreatic duct
Congenital anomaly where the ventral pancreas encircles the 2nd portion of the duodenum
annular pancreas
Annular pancreas may present as ____ sign
double bubble
- dilated stomach and duodenal bulb
Are serous cystadenomas cancerous
no, benign
pancreatic serous cystadenoma assoc with
von Hippel-Lindau disease
pancreatic serous cystadenoma formely called
microcystic cystadenomas
pancreatic serous cystadenoma sf
cluster of grape like cyst
external lobulation
pancreatic serous cystadenoma, when cyst are small, the mass may be
echogenic and appear solid with through transmission
Are mucinous cystic neoplasm common
no
mucinous cystic neoplasm formerly called
macrocystic cystadenoma or cystadenocarcinoma
mucinous cystic neoplasm malignant
yes or potenially malignant
mucinous cystic neoplasm sf
large multicystic mass with numerous septation and debris.
Is it difficult to distinguish mucinous or serour cystic neoplasm
yes
Increased Catcinoembryonic antigen in a pt with multicystc panc mass would suggest diagnosis of
mucinous cystic neoplasm
Tumor of the panc islet cells are common or uncommon
uncommon
Islet cell tumors (endocrine tumors)
Function tumors are
small and difficult to localize
Islet cell tumors (endocrine tumors) assoc with
multiple endocrine neoplasm
von hippel lindau disease
Islet cell tumors (endocrine tumors) insulinoma
- most common
- usually benign
- hyperinsulinemia: thus hypoglycrmia
- no predilection exists for a specific site within the pancreas
Islet cell tumors (endocrine tumors) Gastroinoma
- Zollinger-Ellison Syndrome
- 2nd mots common tumor
- gastric and hypersecretion
- gastric and duodenal ulceration
- frequently malignant
Other islet cell tumors
- glucagonoma
- vipoma
- somatiostatinoma
Where are Islet cell tumors (endocrine tumors) commonly located
body and tail
Multiple endocrine neoplasia is an
inherited endocrine disorder
MEN syndrome is catagorized into
type 1 and 2
MEN Most common site of involvement
Parathyroid
hyperparathyroidism
MEN Most common site of involvement
Pancreatic duct
gastroinomas
insulinomas
MEN Most common site of involvement
pituitary glands
prolactinomas
MEN Most common site of involvement
Adrenal gland
pheochromocystoma
MEN Most common site of involvement
Thyroid
medullary thyroid carcinoma
