Q

Idiopathic interstitial pneumonia generally denotes inflammation of what?

Study These Flashcards
A

Alevolar septa

23
Q

interstitial pneumonia has what differential list?

Study These Flashcards
A 
Idiopathic
Eosinophilic
Systemic lupus
Allergic
Toxins (smoking)
Neoplasia
24
Q

What needs to be excluded to make the diagnosis of idipathic pulmonary fibrosis?

Study These Flashcards
A

Drugs/Toxins
Environmental exposures
Collagen vascular diseases

25
What is the histopathologic difference between idiopathic pulmonary fibrosis in cat/humans and dogs?
Dogs deposit collagen with no fibroblastic foci.
26
Pulmonary fibrosis requires a what for definitive diagnosis?
Biopsy.
27
Predominant carcinomas of the lungs?
Adenocarcinoma Bronchoalveolar carcinoma SCC
28
How can primary lung tumors cause anemia?
Erode the vessels and cause bleeding.
29
Pulmonary hypertension is what?
Pulmonary systolic pressure >30mmHg - needs cardiac catheterization for definitive diagnosis
30
Doppler echocardiography can estimate pulmonary artery pressure where?
Pulmonary or tricuspid valvular insufficiency
31
Three ways to cause pulmonary hypertension?
Venous obstruction Increased pulmonary blood flow by congential lesion Increased vascular resistance.
32
Increased vascular resistance can happen due to?
Response to V/Q (ventilation and perfusion) mismatch. Chronic lung disease PTE HW Endothelial dysfunction Vascular remodeling - VenoOcclusive disease
33
What does A-a gradient mean?
Alveoli-arteriol gradient. The amount of oxygen in the alveoli vs in the blood. It tells you how well the transfer of blood is happening. Ex. High A-a gradient when there is a PTE or right to left shunt. High Alveoli concentration of O2 but low arteriol.
34
What is V/Q mismatch?
When ventilation does not match perfusion... ex PTE, chronic lung disease.
35
Why are the lungs a common place for PTEs?
Slow flow area.
36
Etiologies that predispose animals to PTE?
``` Trauma Surgery Hyperviscosity Neoplasia Cushings IMHA Hyperlidemia Glomerulopathies Pancreatitis Cardimyopathies. ```
37
Where do most PTEs occur?
Caudal lungs
38
Radiographic signs of a PTE?
``` Blunted arteries Wedge shaped alveolar or interstitial patterns Hyperlucent lungs Right sided heart enlargement Mild pleural effusion ```
39
Etiologies for pulmonary edema
``` Hypoalbuminemia Toxins - Cisplatin in cats, snake venom Uremia Pancreatitis PTE Neurogenic - Seizures and head trauma. ```
40
What other clinical signs are seen with ciliary dyskansia?
Sperm motility Earing loss Hydrocephalus
41
What is Kartaganders consist of?
Ciliary dyskansia rhinosinusitis Bronchiectasis Situs inversus
42
MPA to Aorta ratio for hypertension on CT?
>1.6 is considered hypertension
43
Other weird reason for pulmonary hypertension?
Chronic PTE
44
Where are most PTEs located?
Caudal lungs
45
Specific thrombus window and level is?
100 WL and 700WW
46
What is another reason for airtrapping and dilated bronchi see on CT besides bronchial disease?
PTE
47
Tracheal in cats is rare and likely secondary to what?
Other obstructive disease.... trauma, FB
48
Oslerus osleri is seen in what age of dog?
YOUNG 2 yo or less
49
What are the common mycotic diseases?
Blastomycosis Histoplasmosis Coccidiodmycosis
50
What CT sign is indicative of pulmonary fibrous?
Honeycombing
51
What is the number 1 mediastinal mass in cats?
Lymphoma Others include Thyroid carcinoma thymoma parathyroid carcinoma
52
Common cause for pyothorax?
idiopathic
53
When to check a pyothorax on rads?
1-2 days to ensure chest is empty. The day of removal of chest tube 1 week after removal and 1 month after removal.
54
Easy ddx for panting or tachypneic dog?
Systemic hypertension
