Reverse Common small parts pathology test Flashcards
smooth rounded edges do not invade surrounding tissue rounded or oval long axis parallel to the chest wall isoechioc with normal breasat tissue
appearance of benign lesions of the breast
Reverse deck
irregular walls often spiculated margins which are finger like extensions extending out in numerous directions from the mass disrupt normal breast tissue and cause nipple retraction and skin dimpling due to pulling on coopers ligament sharp angular margins microlobulations taller tan wide hypoechoic with weak internal echoes
appearance of malignant lesions of the breast
Reverse deck
fibroadenoma growth stimulated with estrogen develop due to failure of the fibrous and epithelial cells to regress during the 2nd 1/2 of the menstrual cycle
most common benign breast tumor
Reverse deck
large rounded lobulations oval, homogenious, wider than tall
appearance of fibroadenoma
Reverse deck
changes from oval to round echogenic hilum becomes more difficult to detect same shape when you turn on it
appearance of malignant lymph node
Reverse deck
graves disease
most frequent cause of hyperthyroidism
Reverse deck
women over 30
graves disease affects
Reverse deck
hypoechoic gland with diffuse enlargement no discrete nodules intense color doppler-thyroid storm inferno
appearance of graves disease
Reverse deck
bulging eyes agitation weight loss
patient with graves disease
Reverse deck
radioactive ablation with lifelong supplements of sinthroid
treatment of graves disease
Reverse deck
hashimoto’s disease
most common form of thyroiditis
Reverse deck
affects middle aged women autoimmune disorder
hashimoto’s disease
Reverse deck
enlarged homogeneous hypoechic thyroid texture discrete nodules less common acute stage has less vascularity chronic stage will have increased color doppler when TSH elevates atrophic stage depicts small, heterogeneous gland that is hypovasvular
appearance of hashimoto’s disease
Reverse deck
variable size homogenous not necessarily associated with thyroid enlargement range from anechoic to hyperechoic commonly have a peripheral halo hyperfunctioning adenomas can have increased blood flow
appearance of thyroid adenoma
Reverse deck
variable sonographic appearance, usually enlarged, irregular, nodular, heterogeneous,and often not symmetrical most have similar appearance to thyroid adenomas, including halos and homogenous echogenicity nodules may also have cystic areas, calcifications an colloid cyst formation
appearance of mutinodular goiter (nodular hyperplasia)
Reverse deck
nodular hyperplasia (multinodular goiter)
most common thyroid abnormality
Reverse deck
cavernous hemangioma usually asymptomatic and discovered incidentally
most common benign tumor of the liver
Reverse deck
hyperechoic and typically has posterior enhancement usually the right lobe and near the dome
appearance of cavernous hemangioma
Reverse deck
focal nodular hyperplasia women under 40 and asymptomatic
2nd most common benign mass of the liver
Reverse deck
most in right lobe hyper to iso echoic many have central scar
appearance of focal nodular hyperplasia
Reverse deck
fatty liver/fatty sparing
an acguired diffuse disorder resulting in an accumulation of triglycerides with the hepatocytes
Reverse deck
not always uniform and can present focal fatty liver (patchy distibution) focal sparing (mass like hypoechoic regions in and echogenic liver) often near the GB @ the porta hepatis, caudate lobe, and left lobe
appearance of fatty liver/fatty sparing
Reverse deck
liver echogenicity compared to right kidney
most important in making diagnosis of fatty liver
Reverse deck
riedels lobe
congenital varient of liver
Reverse deck
anterior projection of the liver extending to near the iliac crest not merely an elongated inferior posterior segment extending over the right kidney
appearance of riedels lobe
