Dot-dash calcifications
Associated with ductal carcinoma
Dermoid (ovarian) Rx
Surgery, due to risk of torsion and rupture, also small malignant risk
Renal artery stenosis doppler

MRS in prostate cancer
Raised choline

Reduced citrate
Relevance of density of calculus on CTKUB

Benign metastasizing leiomyoma
Unusual variant of fibroids with tumours in the lungs, lymph nodes or peritoneal nodules

Vesicoureteric reflux
Ix for solid, <1cm, enhancing renal lesions
Repeat CT 3-6 months
Sporadic aniridia
Abscence of the iris, associated with nephroblstomatosis and Wilms

RCC more likely to distort the renal contour
Peutz-Jehgers syndrome
Mucocutaneous pigmentation,
GI Hamartomatous polyps,
Mucinous tumours of the ovary,
Minimal deviation adenocarcinoma of the cervix
Parathyroid adenoma on sestaMIBI
Increased uptake in delayed phase only
Localized renal cystic disease vs multilocular cystic nephroma
