Anteriorly

4

A rt adrenal tumor will displace the rt renal vein ____

Anterior

5

Panc tail will displace the left adrenal ___

Posterior

6

What 3 arteries perfuse the adrenal glands

supra renal branch of inferior phrenic artery, supra renal branch of the aorta, and supra renal branch of the renal artery

7

The rt supra renal vein drains into

IVC

8

Lt supra renal vein drains into

left renal vein and then the IVC

9

Phenochromocytoma

In the adrenal medulla, organ of Zuckerkandl (near aortic bif), paravertebral sympathetic ganglia

Cause hypersecretions of catecholamines; dopamine, norepinephrine, and epinephrine.

Symptoms: headaches, palpitations, excessive perspiration.

10

Medulla secretes

Catecholamines which secrete epinephrine and norepinephrine

11

What 4 criteria define a non functioning cortical Adenoma

1. A unilateral mass
2. No history of malignancy elsewhere
3. No biochemical evidence of adrenal hyperfunctioning
4. Adrenal mass < 3 cm in diam

12

3 most common primary mets to adrenal

Lung, breast, and melanoma

13

Adrenal myelolipoma

Echogenic mass with propagation speed artifact

14

2 tumors that arise from medulla

Phenochromocytoma and neuroblastoma

15

Adrenals located in the

Anterior pararenal space

16

Adrenal gland

2 endocrine glands

Cortex and Medulla

17

Right adrenal pyramid lies ____ to IVC, ____ to rt liver lobe, ____ to diaphragm, and _____ to kidney

Post/lat to IVC
Medial to right liver lobe
Lateral to diaphragm
Sup to ant kidney

18

Right adrenal shape

Upside down Y or V shape

19

Left adrenal shape

Crescent shape or triangular

20

Left adrenal lies ____ to lesser sac, ____ to pancreas, ____ to kidney, ____ to diaphragm

Posterior to lesser sac
Post/lat to panc
Ant/medial to kid
Post on diaphragm

21

Blood supply

Suprarenal branch of inferior phrenic art
Suprarenal branch of Aorta
Suprarenal branch of Renal artery

Right supra renal vein empties into IVC
Left suprarenal vein empties into left renal vein

22

Cortex

Secretes steroids
medullocorticoid, menurolocorticoid: regulates electrolytes and secretes aldosterone)
Glutocorticoids
Cortizone
Hydrocortizone
Androgen
Estrogen

23

Medulla

Secretes catecholamines

Epinephrine, norepinephrine

Fight or flight response

24

Addisons Disease (adrenocortical hypo functioning)

Chronic primary hypoadrenalism, atrophic gland

Dec cortisol

Skin color changes, sodium & potassium retention, Renal impairment, dec blood volume, sugar, lipids, fatigue, weak, hypotension, GI distress

Enlg adrenal with possible necrosis

Steroid therapy treatment

25

Adrenogenital syndrome
Adrenal hyperplasia

Inc sex hormones, develop male characteristics muscle hair

Excess androgen production, ambiguous genitalia,

26

Conn's Syndrome (hyperaldosteronism)

Primary hyperaldosteronism, excessive secretion of aldosterone

Hypernatremia (inc sodium), hypokalemia (dec potassium),
Water retention
HTN***
Muscle weak, cramps
Altered renal function

Hyper aldosterone

27

Cushing's Syndrome (adrenocortical hyperfunctioning)

Hyperadrenalism
Hypercorticolism
Inc glucose production

Protruding abdomen, poor wound healing, prone to infection, thin skin bruise easy, moon face, buffalo hump

Upper body obesity, round moonface, inc fat around neck = buffalo bump, thinning of arms & legs

Osteoporosis, hyper pigmentation, htn, virilization

28

Waterhouse Friderichsen Syndrome / acute hypoadrenalism

Massive destruction of gland

29

Hemorrhage

MC in newborns bc large adrenal and inc vascularity
From hypoxia

Hemorrhage and liquefaction
Anechoic(older) to Echogenic, ca+
