focal nodular hyperplasia
adenoma
liver cysts
haemangioma more lkely in males than females t/f
false
how is haemangioma typically diagnosed
US (echogenic spot, well demarcated)
CT - venous enhancement from periphery to center
MRI - high intense area
no need for biopsy
treatment for haemangioma
none
name given for benign nodule formation of normal liver tissue
Focal Nodular Hyperplasia (FNH)
classical clinical feature of FNH
central scar contaooning a large artery, radiatin branches to periphery
FNH is usually symptomatic, however what may be a symtpom
ab pain
FNH diagnosed through ultrasound t.f
true

true
10:1 ratio female - male
hepatic adenoma diagnosed by
US (filling defect)
Ct nd MRI used also
t/f biopsy required for hepatic adenoma
true
rule out malignancy
treatment for males for hepatic adenoma
surgical excision (higher risk of malignancy) q
treatment for woman for hepatic adenoma
stop hormones, weight loss
<5 - annual MRI
>5 - surgical excision
differences between adenomaa and FNH
only hepatocytes, FNH contains all liver structre (bile ducts ect)
adenoma - may lead to malignancy
