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
Inflammation of the bile ducts
Cholangitis
Inflammation of the pancreas
Pancreatitis
Increased amylase and lipase
Pancreatitis
Inflammation of typically the terminal ileum and colon that affects all layers of the bowel
Crohn’s
Affects the colon and rectum, inflamed mucosa and submucosa layers
Ulcerative colitis
Presents as RLQ pain and tenderness, leukocytosis and peritoneal irritation
Acute appendicitis
Blind ended, non moving, non compressible tube >6mm in AP diameter
Sonographic appearance of appendicitis
Distension of appendix with mucous
Mucocele
Outpouching of bowel wall
Diverticula
Inflamed diverticula
Diverticulitis
Obstruction caused by twisting bowel
Volvulus
Most common splenic sonographic finding in patients with AIDS
Moderate splenomegaly
Pseudomembranous colitis is linked to what?
Antibiotic therapy
Underlying cause of acute appendicitis
Obstruction of the lumen
Sonographic appearance of acute pancreatitis
Hypoechoic and enlarged
Flank pain, fever, frequent/urgent urination, increased WBC, pyuria, hematuria
S/S of UTI’s
Inflamed renal tubules caused by E. coli
Acute pyelonephritis
Sonographic appearance of acute pyelonephritis
Usually normal, loss of CM junction, renal enlargement, compression of sinus, altered echotexture, +/- gas
Cortical scarring, asymmetrical changes, atrophy, dilated blunted calyces
Sonographic appearance of chronic pyelonephritis
Complication of pyelonephritis that may decompress into collecting system of perinephric space
Abscesses
Pus in the collecting system
Pyonephrosis
Causes a thick bladder wall and decreased bladder capacity
Cystitits
Loss of voluntary control of voiding
Neurogenic bladder
Enlargement of the prostate and night time urination (nocturia)
Benign prostatic hyperplasia (BPH)
Inflammation of the prostate and seminal vesicle
Prostatitis
Exudative pleural effusion is seen with…
Infections & neoplasms
Most frequent cause of LUQ mass
