Objectives: After studying the article titled “Splenic Abscess Detection and Monitoring Using Sonography,” you will be able to:
Describe the common pathogenic mechanisms for splenic infections.
Discuss the sonographic features of a splenic abscess.
Develop a sonographic follow-up protocol for assessing the treatment of a splenic abscess.
Possible pathogenesis for splenic infections resulting in splenic abscess is typically defined by how many categories?
Two Three Four Five
The most frequent gram-negative bacillus causing splenic abscess is
Pseudomonas aeruginosa
Helicobacter pylori
Klebsiella pneumoniae
Escherichia coli
What percentage of the time are splenic abscesses caused by infectious sources external to the spleen?
70% 75% 80% 85%
Early sonographic features of a splenic abscess include the following except
Inflammatory rim Well-defined borders Oval shape Posterior enhancement
Late sonographic features of a splenic abscess include the following except
Rounded shape Iso/hypoechoic interior Well-defined borders Posterior enhancement
Splenic abscesses in children are most likely to appear as a
Unilocular abnormality Multilocular abnormality Singular abnormality Hyperechoic, irregular abnormality
If not treated early and aggressively, the mortality secondary to splenic abscess can be as high as
35%–40% 45%–50% 55%–60% 65%–70%
For every hour of delay in the onset of treatment for a splenic abscess, morality increases by
3% 5% 7% 9%
The most common complication of sonography-guided prostate biopsy is
Pelvic discomfort Hematuria Rectal bleeding Dysuria
Urosepsis occurs with approximately what frequency following sonography-guided prostate biopsy?
2% 1% 0.5% 0.25%
