Title: The Azygous Fissure – The Migrating Vein
Title: The Azygous Fissure – The Migrating Vein
(Verse 1 – The Anatomy)
This song is about the Azygous Fissure
An anatomic variant to measure
Found in the right upper lobe
An inverted comma shape appearing on the plane
It separates the apical segment part
A unique design of anatomical art
(Chorus – The Teardrop)
The azygous vein sits at the bottom of the fissure line
A classic and distinctive sign
It forms the Azygous Lobe lying medial to the fissure
But in fact it is not a true lobe to be sure
(Verse 2 – The Mechanism)
The vein travels through the lung tissue deep
Instead of medial where it should be
It drags the pleura down in its track
Four layers of pleura front to back
Two visceral and two parietal layers meet
To make the fissure complete
(Outro)
The Azygous Fissure is the name
A benign variant in the imaging game
No disease or pathology to fear
Just the vein and the fissure here
Poem: The Four-Layered Fold
The vein migrates through the upper lobe
A path distinct around the globe
Dragging pleura, four layers deep
A comma shape the x-rays keep
Not a true lobe, but a medial zone
Where the azygous vein stands alone
