2. Case 1

4. Dx: Round Atelectasis
•Always associated with chronic diseases and
adjacent pleural disease.
•Represents infolding of the viscreal pleura as
isolated area*.
•Development of fibrous adhesions suspending
the rounded atelectasis area in elevated and
tilited position.

5. •The vessels leading to the mass are crowded,
and they tend to diverge and arc as they reach
the mass giving the appearance of “comet tail
sign”.
•-May slowly resolved or remain unchanged on
serial CXR or CT scans.
•may have air bronchogram.

6. To confidently suggest the diagnosis of
“Round Atelectasis”:
•Three criteria must be met:
.1Contiguity with chronic pleural
effusion/thickening.
.2Typical appearance of crowded vessels and
bronchi sweep into the base of the
atelectatic lung.
.3Volume loss in the affected lobe.

7. Case 2

11. • Lumbar hernia occur through defects in the
lumbar muscles or the posterior fascia below the
12th rip and above the iliac crest.
• They usually occur after surgery or trauma
• There are two types of lumbar:
1. Grynflett-lesshaft “superior lumbar triangle.”
2. Petit “inferior lumbar triangle”
• Diffuse lumbar hernia may also occur usually
after flank incsion in kiney surgey

13. Case 3

15. • Bilateral Interfacetal dislocation, also called
“bilateral locked facet”
• Hyperflexion injury caused by complete
disruption of all spinal ligmanets and results in
anterior dilocation of the vertebra >50%
• Unstable c.spine injury with high risk of cord
damage.
• Typically occur in lower cervical spine.

16. • Facet dislocation can occur to varying degrees:
• subluxed facets
• perched facets
• locked facets
