CR&R Final Flashcards
What is shown here in this photo? What may it increase the risk of?
Ventricular fibrosis (likely secondary to MI, dead tissue -> replaced with fibrotic tissue)
It can increase the risk of systemic thromboembolism (dead tissue doesn’t contract, leading to blood pooling)
What additional anatomic abnormality is found in 5% of patients with a bicuspid aortic valve?
Coarctation of the aorta
How can aortic stenosis and a bicuspid aortic valve be differentiated?
How can rheumatic fever and rheumatic heart disease be differentiated?
What are these three histological features from left to right? What disease are they associated with?
What acronym is used to describe the symptoms of infective endocarditis?
What are major differences between valve damage in RHD vs IE?
RHD- mostly along closure line, no chordae tindinae involvement
IE- More clumped, can destroy, vegetate CT
What type of cardiomyopathy can be precipitated by ethanol?
Dilated cardiomyopathy
*Anthracyclines (doxorubicin) are another common cause of DCM
Identify the diferent CM and their features using this chart:
Good job!
What is cystic medial degeneration? What 3 CT disorders is it seen in? What additional two pathologies? What is the main cause of myxoid degeneration?
Where are arterial plexiform lesions seen?
Pulmonary hypertension
What finding is characteristic of the exudative phase of ARDS?
Alveolar hyaline membranes
Which respiratory tract structure is most affected by emphysema due to smoking?
Respiratory bronchiole (centriacinar pattern affects respiratory bronchiole more than alveolar duct, which would be more affected in panacinar pattern from a1anti-trypsen deficiency)
What are major differences between centriacinar and panacinar emphysema?
What are the two notable subtypes of NSIP pattern?
Cellular (left)
Fibrotic (right)
What characteristic of end stage lung disease is seen here?
Honeycomb lung
Which arrow represents subepithelial space? Which represents subendothelial space (for deposits)?
Blue- Subendothelial
Purple- Subepithelial
What patient population would be at highest risk for a BK polyomavirus infection?
A kidney transplant patient (immunocompromised)
Which of these pictures of acute pyelonephritis? Which is chronic?
Chronic pyelonephritis (left)- Not as many WBC casts, mostly lymphocytes in interstitium
Acute pyelonephritis (right)- Neutrophils in the tubular lumen (contributing to WBC casts)
What type of pyelonephritis is visible here?
Chronic pyelonephritis
*Note prominant scarring
What type of renal artery stenosis is seen here?
Fibromuscular dysplasia
*Most commonly seen in young to middle-aged women
What is the most common disease cause of full house immunofluorescence?
Systemic lupus erthematosus
What tumor is characteristic of a triphasic appearance? What are the three layers? What do abnormally large, hyperchromatic cells (right) indicate about that particular Wilm’s tumor?
Wilm’s tumor (epithelium, blastema, stroma)
Anaplasia: Most common in P53 mutations. resistance to chemotherapy
Irregular spikes on silver stain are most indicative of what pathology?
Membranous glomerulonephropathy
How does the gross presentation help to differentiate between oncocytoma and chromophobe carcinoma?
The classic brown color of the renal tissue
Glycosuria can be associated with what two conditions?
Diabetes mellitus
Fanconi syndrome
What effect will NE have on HR, BP, and SVR?
BP and SVR: Increased
HR: Decreased due to reflex bradycardia
Will the urine Na+ be high or low in SIADH?
Normal Na+ in urine (just ADH secreted abnormally, not aldosterone)
What syndrome can directly result from a bad PE?
ARDS
