Angiomyolipoma is a type of what?
Hamartoma (i.e normal tissue in the wrong order)

Incidentally
Are renal cysts single or multiple?
Can be either (more commonly single)
What are most benign asymptomatic renal lesions?
Renal cysts
How are renal cysts investigated?
USS Contrast CT (define whether there's enhancement)
Which types of tissue compose of angiomyolipoma?
Blood vessels
Muscles
Fat
How is angiomyolipoma investigated?
CT
What is the issue with angiomyolipoma?
Blood vessels are very fragile so haemorrhage risk
What is Wunderlich’s syndrome?
Risk of spontaneous haemorrhage in angiomyolipoma 4-6cm causing systemic collapse due to retroperitoneal bleeding
How are angiomyolipomas treated?
Embolization

What is von hippel-lindau syndrome?
Familial syndrome causing multiple renal tumors
How is renal cell cancer diagnosed?
USS (not diagnostic but initial investigation of mass)
CT (triple phase contrast) - diagnostic
Biopsy (high false negative phase)
How is renal cell carcinoma staged?
Robson: 1 - within capsule 2 - invasion into perinephric fat 3 - involvement of regional lymph nodes +/- veins 4 - local spread or distant metastases
