Infectious & Inflammatory Diseases Flashcards
Fever, pain, leukocytosis
Clinical presentation for infection & inflammation
“-itis”
Indicates an inflammatory process
Localized collection of pus
Abscess
Inflammation of the liver
Hepatitis
Hepatitis routes for A, B, C, D
A: fecal-oral
B: blood and body fluids
C: transfusions
D: dependent on hep B
Hepatomegaly, decreased liver echogenicity, prominent portal vein walls, thickened GB
Acute hepatitis
Coarse liver parenchyma, increased echogenicity, portal HTN, cirrhosis
Chronic hepatitis
Simple to complex cyst in the liver, shaggy walls, internal septations, echogenic foci with posterior reverberation (gas)
Bacterial infection
Candidiasis
Yeast infection
Uniformly hypoechoic, “bulls eye” or “wheel in wheel” appearance
Candidiasis
Opportunistic infection
Pneumocystis carinii
Amebiasis
Parasitic disease
Hydatid disease
Parasitic tapeworm. Most common to occur in RT lobe
Schistosomiasis
Parasitic infection
Opportunistic infection that starts in the lungs and may affect many organs
Tuberculosis
Peritonitis
Inflammation of the peritoneum
Name some infectious and non infectious factors for peritonitis
Infectious: bacterial, fungal, etc
Non infectious: pancreatitis complications, reaction to foreign bodies
Most often due to impacted stones
Acute cholecystitis
GB wall >3mm, hyperaemia, gallstones, impaction at neck, GB hydrops, + Murphy’s sign
Sonographic appearance of acute cholecystitis
Lab values with acute cholecystitis
Serum bilirubin, ALP, WBC, AST, ALT
Necrosis of the GB
Gangrenous cholecystitis
Typically occurs at fundus of GB, free fluid in peritoneal cavity
Perforation
Emphysematous GB
Caused by gas forming bacteria and is more common in men and diabetics
Inflamed GB without stones
Acalculous cholecystitis
Appears as acute cholecystitis without stones
Acalculous cholecystitis
Most common form of symptomatic GB disease
Chronic cholecystitis
Lab values with chronic cholecystitis
AST, ALT, ALP, BILI
What is chronic cholecystitis associated with?
The development of GB carcinoma
Impacted stone in the cystic duct, GB neck or Hartmann’s pouch or compression of the CHD
Mirizzi Syndrome
Dilated ducts above level of obstruction but CBD normal
Sonographic appearance of Mirizzi
Xanthogranulomatous cholecystitis
Rare form of chronic inflammation of GB
Appears as a calcified GB wall
Porcelain GB
