Normal vasculature?
Big arteries and veins *Fluid overload*
26
Normal vasculature?
Big arteries and veins *Left to right cardiac shunt*
27
Normal vasculature?
Big arteries and veins *Left to right cardiac shunt*
28
What are causes of small arteries and veins?
Common: hypovolemia, shock Uncommon: Addison's disease, severe pulmonic stenosis, R to L cardiac shunt (tetralogy of fallot)
29
Normal vasculature?
Small arteries and veins
30
Normal vasculature?
Small arteries and veins
31
What are causes of big arteries, normal veins?
Pulmonary hypertension Heartworm disease Thromboembolism (rare)
32
Normal vasculature?
Big arteries, normal veins *Heartworm disease*
33
Normal vasculature?
Big arteries, normal veins *Heartworm disease*
34
What are causes of big veins, normal arteries?
Venous congestion due to left-sided heart congestion (mitral valve degeneration, cardiomyopathy)
35
Normal vasculature?
Big veins, normal arteries *HCM, L sided CHF*
36
What are causes of multiple nodules/masses in the lungs?
Metastatic neoplasia (most common) Granulomas (fungal disease, feline asthma)
37
What are causes of solitary nodules/masses in the lungs?
Primary lung tumor (esp if one mass) May be early metastatic neoplasia
38
Metastatic neoplasia *Large nodules*
39
Metastatic neoplasia *Miliary nodules*
40
Nodule
41
Nodule
42
What are some examples of things that mimic pulmonary nodules?
Pulmonary osteomas End-on vessels Dermal structures (nodules, nipples) Costochondral junction remodeling
43
Pulmonary osteoma Very common, benign **Mineral opaque, often point but can be round** Often in lung periphery
44
Pulmonary osteoma Very common, benign **Mineral opaque, often point but can be round** Often in lung periphery
45
Pulmonary osteoma Very common, benign **Mineral opaque, often point but can be round** Often in lung periphery
46
Pulmonary osteoma Very common, benign **Mineral opaque, often point but can be round** Often in lung periphery
47
Pulmonary nodules
48
How can you distinguish pulmonary osteomas and pulmonary nodules?
Nodules: usually round and smooth, soft tissue opaque, similar opacity as similar size vessel Osteomas: sharp edges/weird shapes, mineral opaque, will be visible at a smaller size
49
End on vessel *Same size as vessel, more opaque than a same-size soft tissue nodule*
50
End on vessel *Same size as vessel, more opaque than a same-size soft tissue nodule*
51
Compare the appearance of end-on vessels vs end-on airways
Vessels will be very opaque, in the path of a vessel Airways will be lucent because they contain stack of gas
52
End on vessel *Same size as vessel, more opaque than a same-size soft tissue nodule*
53
End on vessel *Same size as vessel, more opaque than a same-size soft tissue nodule*
54

Costochondral junction remodeling Old dogs *Mineral opaque, usually irregular, can be smooth/round*
