Striated hypo post to kidneys

Quadratus lumborum

1

Kidneys lie in

Perirenal space

2

Peri aorta several hypo meas > 2 cm adj to the celiac trunk and SMA. Most likely

Para aortic lymph nodes

3

Ab pain, inc serum amylase, fluid pocket in left pararenal space. Most likely

Pancreatic pseudocyst

4

Aorta

5

See lymph nodes adj to Abd aorta. Should include

6

Patient has pheochromocytoma. Evaluate

Adrenals

7

Hx of lung cancer. MC mets from lung is ___ evaluate

Adrenals

8

Right adrenal gland location

Post to IVC

9

Looking for lymphadenopathy search

Splenic hilum, porta hepatis, renal hilum, and para aortic area

10

Striated posterior medial to kidney

Psoas muscle

11

Differentiating renal vs adrenal mass

Scan patient during deep inspiration and expiration. Adrenals are fixed. Kidneys will move.

12

Simulates adrenal mass

Thick diaphragmatic crus
Accessory spleen
Gastric Diverticulum
Retroperitoneal lymphadenopathy

13

Anatomic relationship of left adrenal gland

Lateral to the Abd aorta and diaphragmatic crus

14

Location of right diaphragmatic crus

Posterior to ivc and right renal artery

15

Criteria asses Nodular disease

Only lymph nodes meas > 1 cm are abnormal

16

Palp mass post renal tx anechoic mass with multiple septations lateral to midline

Lymphocele

17
